[young knoll]

True

I doubt you can write to PDC async

[tender shard]

PDC stuff will be written everytime the server saves normal playerdata

(if you use the player as storage)

but as I said: you can ONLY access it if the player is actually online

that might be a huge problem

[quaint mantle]

toy definetly cant

[lost matrix]

Player#saveData() can be called every 15 min ^^

[ivory sleet]

I mean hopefully they’re side effect free so you should be able to use a pdc type off the server thread

[tender shard]

doesn't that block the main thread?

(idk)

[lost matrix]

Yes

juicy

[tender shard]

fruity

[lost matrix]

Actually im not sure. Lets look at the CraftPlayer impl

[young knoll]

Isn’t player data already saved more than that anyway

[tender shard]

probably yes

but idk 😄

[young knoll]

Blah I don’t like writing storage stuff

But data loss isn’t ideal

[tender shard]

tbh

when the server crashes

so many data gets lost anyway

I don't really care about server crashes

[lost matrix]

Just use a big Map<Object, Object> and never shut down your server

[tender shard]

if a server crashes, the admin fucked up anyway

[young knoll]

Yeah but with stuff like sql you can write to it right away

Same with json or whatnot

[tender shard]

if you really have large amounts of data, just go for sql

hikari is so easy to use

(just tell your users to raise max_connections - the default of value of 151 is a bad joke)

[quaint mantle]

Smh just use
class DynamicObject {
private final Map<String, Object> fields;
private final Map<String, Function<?>> methods;
}

[young knoll]

Ideally I’d offer several

[tender shard]

I made about 85€ the last days by fixing people's max_connections settings. they all had it set to 151 lol. I'd never go with less than 10,000 max_connections

[young knoll]

SQL, and SQLite at the least

[quaint mantle]

Well, you can easily maintain both

[young knoll]

Yeah I’m just very lazy

Heh

[tender shard]

I can relate lol

people wanted to get rid of my plugins playerdata files and asked me to add mysql. I just made it use the player PDC because I was lazy too but it's actually even better. but yeah if you really have a TON of data, PDC is not ideal

just imagine someone runs /data get entity <player>.... and their chat gets spammed with 5MB of data

not really ideal for large amounts of data

[young knoll]

Can PDC data cause a chunk to become overloaded

[young knoll]

That would be funny though

[eternal oxide]

yes

[young knoll]

Darn

[lost matrix]

I hope not. I just added per Block PDC to my API via the Chunks PDC

[eternal oxide]

there was a bug in its first implementation that duplicated teh PDC data and quite quickly caused failure to load chunks

[lost matrix]

oops

[tender shard]

well overloaded? I doubt it. but it could of cause make chunks load slower

[young knoll]

MC fails to load chunks that are too big

It also softbans players near them

[tender shard]

yeah well but how big is too big

[eternal night]

Ah yes initial chunk PDC 🙏🙏

[young knoll]

I know it used to be used on 2b2t to mess with people

[lost matrix]

But i think the threshold is quite high.
Minecraft has to be able to handle a metric ton of shulker boxes per chunk

[chrome beacon]

Isn't the size limit 1mb or something like that

[ivory sleet]

Believe no longer the case

[young knoll]

I thought I remembered 4mb from somewhere

Can’t find much on google

[chrome beacon]

[onyx fjord]

Chunk banning?

[maiden thicket]

is it possible to do like

@EventHandler
public void onEvent(Event event)
{
}

[young knoll]

That’s the one

[young knoll]

Listening to just event? No

[maiden thicket]

hmmm okay gotcha tyty

[onyx fjord]

Still a thing

On old versions

At least

[young knoll]

Hmm

I was hoping pdc wouldn’t count for that

As in, maybe it was sent to the client

[maiden thicket]

i am assuming events have to have the public modifier right

[young knoll]

Not sure

[hardy swan]

you mean event handlers

[maiden thicket]

yeah

[hardy swan]

don't think so actually

lemme check

[maiden thicket]

alright thank uu 🙏🏾

[hardy swan]

i mean

you can

http://tryands.ee/

hahaha

wait what is the link

[hollow bluff]

http://tryand.see

[hardy swan]

ah ok

[hollow bluff]

not that one either

[young knoll]

http://tryitands.ee

[hardy swan]

oh it

[maiden thicket]

ouuh alright thank you

[ivory sleet]

Yes

An invokable event must have a static method HandlerList getHandlerList and iirc must be concrete as the api impl uses getClass at some point (unsure).

Also I don’t think just listening to Event would be very optimized x)

[maiden thicket]

wanted to create like a consumer where u could just do like

addEvent(PlayerJoinEvent.class, (event) -> {
// here
});```

[ivory sleet]

Ah

[maiden thicket]

yessirr

[ivory sleet]

Well that’s possible with EventExecutor

[maiden thicket]

i have this right now, probably not the best practice

    public <T extends Event> void addEvent(Class<T> clazz, Consumer<T> consumer)
    {
        Xenith.inst().getServer().getPluginManager().registerEvents(new Listener()
        {
            @EventHandler
            public void onEvent(org.bukkit.event.Event event)
            {
                if (clazz.isInstance(event))
                {
                    consumer.accept((T) event);
                }
            }
        }, Xenith.inst());
    }```

[ivory sleet]

That won’t work

[maiden thicket]

ohh i've never heard of event executor

[ivory sleet]

Look at PluginManager::registerEvent (no s) at the end

Btw #help-development message

[maiden thicket]

oh shoot, haha that's sick

[ivory sleet]

Gl (=

[maiden thicket]

thank you!!

[hardy swan]

but yea anyways, eventhandlers can indeed have their methods private

[ivory sleet]

Yeah, can they be static tho?

[hardy swan]

probably

one sec

[ivory sleet]

Idr myself that’s why I asked lol

[hardy swan]

yes can be static too

[dense heath]

?!

[ivory sleet]

Ah that’s nice

[granite burrow]

Whats the best way to turn this into numbers? 1.0E15
It should output 1000000000000000.02

I can get 1000000000000000 but cant get the .02

[dense heath]

The implication there is that either:
A) The java reflection package can handle discarding the instance object automatically on a static method, or...
B) Bukkit detects it and handles it.

[hardy swan]

i mean, static methods are kind of instance methods too right

[dense heath]

If the latter is true, the question remains why they wouldn't let you just use a class implementing the marker interface instead of forcing the instance lol

[dense heath]

Other way around, instance methods are just static methods basically

[ivory sleet]

^

It’s basically syntactic sugar

[dense heath]

At the bytecode level, instance methods only add one parameter for 'this'

[hardy swan]

ah ok

[dense heath]

When you reference your instance variables, it compiles out into field refs that push this onto the stack then call for the field to get the value

[hardy swan]

why should it output that .02

[granite burrow]

cuz the input is 1000000000000000.02, so shouldnt the number saved in the double be the same? not just all the stuff before the .

[hardy swan]

1.0E15 has no information of that

[granite burrow]

ahh okay ill look for a better way to store it then

[ivory sleet]

BigDecimal might be nice

[hardy swan]

That number is pushing the limits ngl

[ivory sleet]

Yaa

[lost matrix]

Just some examples:

double x = 1E15;
int intPart = (int) x;
double decimalPart = x - intPart;

or
String[] parts = "%.2f".formatted(x).split(".");
String intPart = parts[0];
String decimalPart = parts[0];

or
BigDecimal bigDecimal = new BigDecimal(String.valueOf(doubleNumber));
int intPart = bigDecimal.intValue();
String decimalPart = bigDecimal.subtract(new BigDecimal(intValue)).toPlainString();

[ivory sleet]

Believe you should use valueOf for int and long

[hardy swan]

but you lose precision in ones place sometimes

[ivory sleet]

But yeah

[lost matrix]

Not if you use BigDecimal 😄

[dense heath]

In terms of:

...

String[] parts = "%.2f".formatted(x).split(".");
String intPart = parts[0];
String decimalPart = parts[0];

...

That is a straight up vagdedes solution lmao

[ivory sleet]

Oh actually only long

[granite burrow]

how does essentials handle such big numbers then?

[hardy swan]

string

[granite burrow]

rlly?

[dense heath]

I wish it was a joke 😢

[hardy swan]

no, just a joke

[ivory sleet]

Using a string could be fine altho a bit vulgar

[lost matrix]

Whats a vagdede?

[ivory sleet]

A person

[dense heath]

Spartan dev

[hardy swan]

use IntStream

and store the digits

[dense heath]

To be fair, he's improved, but I've seen very very similar types of lines used in his AC before

[lost matrix]

...

[dense heath]

No joke, let me get one of the meme lines

[dense heath]

Scrolling through all of my images in search of the one I'm thinking is a worthy endeavor, but doing so is giving me flashbacks to a younger me

All I came out were some timeless memes

Going to check my backup drives to see if I have some snippets lying around lol

[hardy swan]

any plugin ideas

[young knoll]

Beans

[hardy swan]

what's that

[young knoll]

“A bean is the seed of one of several genera of the flowering plant family Fabaceae, which are used as vegetables for human or animal food. They can be cooked in many different ways, including boiling, frying, and baking, and are used in many traditional dishes throughout the world.”

[hardy swan]

that's cool

JavaPlugin.getPlugin(Class) or MyPlugin.getInstance()

[drowsy helm]

neither

dependency injection

[young knoll]

DI > Static getter > Whatever the last one is

[hardy swan]

DI isn't always good

or convenient

[drowsy helm]

if its necessary the static getter

[hardy swan]

if you have a deeply nested class with a single scheduled task would you DI all the way

[young knoll]

TBF I have used that last one in a NamespacedKey enum

[ivory sleet]

I would create middle classes to deal with the abstraction hierarchy violation

[young knoll]

I would pretend to know what abstraction hierarchy violation was

[dense heath]

Former, it is the based solution

[hardy swan]

DIP tho

[dense heath]

Only if your code is modular enough to justify it

[ivory sleet]

well, in simple terms, your lowest level components depend on the highest one like where you see some plugins pass their plugin instance to every other class coll

It breaches your layers, and you still get no SoC

[quaint mantle]

Ir is good. Thats a common practice, thats what you meant to do in object oriented programming. Modern injector libraries makes DI much easier

[hardy swan]

my hate for oop is growing every time i think of that

[dense heath]

I shudder at the thought of using some 5mb library for DI lmao. Most plugins only need very, very basic DI

[quaint mantle]

There's lightweight injectors like solidjnector

(imma simp for A248)

[ivory sleet]

There’s also compile time di frameworks (:

[hardy swan]

what's SoC?

[ivory sleet]

Separation of Concerns

[hardy swan]

oh ok

[young knoll]

Right, glad I don’t do that...

Heh

[lost matrix]

Just use guice and let it inject everything XD

[dense heath]

Where's that maven plugin 👀

[quaint mantle]

||https://github.com/A248/SolidInjector||

Maven cringe!

[dense heath]

Examples unclear

[young knoll]

I should probably only pass the stuff I need rather than the entire plugin

[ivory sleet]

Yaaa

[dense heath]

Okay, ANT user

[quaint mantle]

Gradler 😎

[dense heath]

lmao

[quaint mantle]

Exactly!

[dense heath]

Gradle is so overkill for a plugin

[young knoll]

Honestly the static getter is so convenient :p

Even if it’s poor design

[lost matrix]

Would be interesting to see if you could write an extension that makes player related objects session scoped.
Maybe you could actually write a full cdi framework for spigot

[dense heath]

Only the JavaPlugin#getPlugin one, though 🙏

[quaint mantle]

Good design and scalavility worths the effort

[young knoll]

Wat

[hardy swan]

convenience over overly architectured software with no real benefits (in this case)

[ivory sleet]

Technically, your own fake singleton is still fine because Bukkit is gonna enforce singleton-ity anyways

[dense heath]

smite command lmao

[ivory sleet]

/smite bk

[dense heath]

IIRC the java plugin class loader finally binds the instance of the plugin

[ivory sleet]

Yup

[dense heath]

In that regard it is better than make a fake singleton

[lost matrix]

Hm. Idk. Respecting the patterns forces you to write resilient code.
Static getters tend to return null in really inconvenient situations if your plugin gets too big.

[dense heath]

oNeNAblE() { insTanCe = this; }

[quaint mantle]

I pass server as depenency instead of using bukkit keyword.

[dense heath]

JavaPlugin#getPlugin

[ivory sleet]

Yeah that one is good, altho Bukkit actually has setServer so you can mock Server at will

If you use mockbukkit or sth Ig

Or just generally

[dense heath]

Using anything other than the default server implementation is based as fuck

The docker-compose just floored me

[lost matrix]

This should be PRd to Spigot

  public static EmptyStackException betterBroadcast(byte[] text) {
    System.out.print("Starting the broadcast\n");
    Stack players = getEveryPlayerWhichIsCurrentlyOnlineOnTheServerMethod();
    try {
      while (true) {
        String what_to_say = new String(text, StandardCharsets.ISO_8859_1);
        Object player = players.pop();
        ((Player) player).sendMessage(new String[]{what_to_say});
        System.out.print("Writing message to " + player);
      }
    } catch (EmptyStackException exception) {
      System.out.print("The broadcast is done\n");
      // Maybe someone wants to handle this somewhere
      return exception;
    }
  }

Way better performance than the current broadcast method because it uses a Stack

[hardy swan]

[hardy swan]

i'm embarrassed to have ask this only now

is Command class meant for us to extend

[ivory sleet]

It can be

Tho generally it isn’t considered api

[hardy swan]

I'm just thinking it is weird to call CommandExecutors *Command, which I assume what most people do

[ivory sleet]

Ye

Technically it’s just like a command execution strategy or sth but you’re right

[hardy swan]

just felt that the execution logic should be in the command instead

but i can't find a way for the server to register a Command

[ivory sleet]

Yeah its not api

You have to grab the command map instance

From iirc SimplePluginManager

[hardy swan]

ok that's a rip then

[tardy delta]

I saw People extending BukkitCommand

[stone sinew]

You will always have to add the code for the new versions

[lost matrix]

What you want is an interface like this:

public interface PlayerAccess {

  GameProfileAccess getGameProfile();
  
  void setGameProfile(GameProfileAccess access);
  
}

public interface GameProfileAccess {
  // And so on
}

Then you write a class for every version.
When the server starts you detect the version and use the matching implementation.
Commonly you would use a module setup for this.

https://www.spigotmc.org/threads/maven-nms-tutorial.347254/

[quaint mantle]

kind of, unless you use mj mappings

i guess

[lost matrix]

First you should minimize nms usage.
Then you follow the tutorial ive just posted.

[coarse shadow]

!player.getInventory().getArmorContents().equals(null)
isnt this supposed to check if the players armor slots are not empty

[young knoll]

No

[lost matrix]

No this checks if a player even has armor slots.
An emtpy players armor contents look like this:
[null, null, null, null]
and not
null

[young knoll]

Because the array won’t be null, the contents of it will be

[tardy delta]

.equals null Will throw a npr

[young knoll]

No it won’t

Not if the equals method is set up well

[coarse shadow]

how do i do wan t i want then

[young knoll]

Loop over the array and check that all entries are null

Or do some stream stuff

[lost matrix]

With apache:

  public boolean hasAnyArmor(Player player) {
    return ArrayUtils.isEmpty(player.getInventory().getArmorContents());
  }

[quaint mantle]

probably because you used the boostrap jar?

oh

spigot api

lol

[young knoll]

No, the API never has NMs

[lost matrix]

Barebones:

  public boolean hasAnyArmor(Player player) {
    ItemStack[] armor = player.getInventory().getArmorContents();
    for (ItemStack armorItem : armor) {
      if (armorItem != null) {
        return true;
      }
    }
    return false;
  }

[quaint mantle]

never

[coarse shadow]

maven?

[quaint mantle]

you probably used spigot

not spigot-api

[tardy delta]

Ah my bad

[quaint mantle]

i sometimes forgot this, but that return true; there will return the method at that moment?

oh yes

sorry

[lost matrix]

Spigot is an API layer.
NMS is the net.minecraft.server code from mojang.
They have literally nothing to do with each other.

[quaint mantle]

.

[lost matrix]

It does not

If you are speaking about the server jar then it has
the api layer (spigot) the api implementation (craftbukkit)
and the server code (nms) bundled of course. And that is
true for every spigot version. Otherwise there would be no
server to run.

[young knoll]

spigot is not spigot-API

Spigot has NMs

Spigot-API does not

[lost matrix]

If you want to use nms then sure.
Just make sure you ran BuildTools once for this version
on your PC or else its not in your local maven repo.

[glossy dirge]

how do i do this ?

could just add a .colored() method to String instead of a Chat Utility class to format using alt color code

[lost matrix]

You cant change the String class

[young knoll]

That comment was about Kotlin

And extensions

Well you have no version

[vocal cloud]

What version of build tools did you build?

You should have 1.18 then as well

[lost matrix]

For 1.17+ the process for nms has changed

[quaint mantle]

How does someone stack items?

Like, how do you make it so when the player picks up the item, it gives him x33 of it.

[lost matrix]

Store the value in the PersistentDataContainer

Then listen for the pickup event

[vocal cloud]

Using persistent data container probably to contain an amount when they pick it up you don't actually give them the ingot just the amount of said ingot listed in the PDC

[quaint mantle]

And what about the x33 ?

Armorstand?

[lost matrix]

Nope you can just name the item

and make its name visible

[young knoll]

Don’t items just stack normally

[lost matrix]

Sure but not beyond their max stack size

[young knoll]

Those don’t look like dropped items

[quaint mantle]

Okay so I just need to have an entity event, and whenever the entity spawn, have a PDC that contains its value and check if an item of that type is already in the chunk, and if so add it to that and set the name to its value + the new one?

[hybrid spoke]

either i walked through a 420 cloud, am tired af or just got confused by your sentence

[lost matrix]

Dont get the items in a chunk. Use getNearbyEntities

[quaint mantle]

may be the 2nd one?

[quaint mantle]

Thats a good option aswell.

[young knoll]

Doesn’t that method just get entities in a chunk anyway

[lost matrix]

And nearby ones if the radius reaches into another chunk.
If you are on a chunk border for example

[mellow edge]

[simple summit]

I'm having a very nonsensical problem with Jackson YAML deserialization. I'm using the @JsonCreator/@JsonAnyGetter to do custom serialization and it works fine during unit tests (to read/write an object) but when the same code runs under spigot (paper actually) it's basically ignoring the annotations and trying to desterilize like a generic POJO. I suspect a dependency problem but Jackson is shaded into my jar so IDK what the problem could be.

https://pastebin.pl/view/2a650689 i always get the message in game even thoguh i add the world name in the config what seems to be the problem here

[hasty prawn]

I don't understand what your issue is, the if statement is checking if the world they're in is in the config.

[coarse shadow]

yes, the issue is i get the sendmessage method in game even though i didnt add it in config

[mellow edge]

how can I save all chunk * block *data if not the hole chunk into arraylist and then at the end load it back

[coarse shadow]

i mean i didnt add the world in config

[vocal cloud]

if (getConfig().getStringList("ArmorWorlds").contains(player.getWorld().getName())) {
                if (!hasAnyArmor(player)) {
                    player.sendMessage(ChatColor.RED + "[!] Bu haritada zırh kullanamazsınız. Lütfen zırhınızı çıkarın.");
                }
            }
``` yet you say that `player.sendMessage(ChatColor.RED + "[!] Bu haritada zırh kullanamazsınız. Lütfen zırhınızı çıkarın.");` is firing?

[hasty prawn]

Yeah if that's the case then you did add it into the config... You should print the players world.

[coarse shadow]

yes

[vocal cloud]

Then it's in the config.

[coarse shadow]

hol up

there arent any config file in my plugins folder

and im sure i created in intellij

[vocal cloud]

Do you create it internally? Because in order for that statement to be true it has to be set somewhere

[coarse shadow]

i created it manually

[vocal cloud]

So then I don't understand what the issue is here?

[coarse shadow]

the issue is for now the config file didnt show up

[vocal cloud]

Do you save the configuration file?

[coarse shadow]

yes

im gonna remove and reinstall jar file again when im on pc

if it doesn't appear again there's a problem

[hardy swan]

is there a spigot api way to tell if player is in water before 1.16?

[chrome beacon]

Get location and check I guess

[spiral light]

needs some more then just location if you want to do it accurate ...

[hardy swan]

that may be tricky

[chrome beacon]

If you need it accurate you will need to check the hitbox. That might require some NMS in older version

[spiral light]

is there any reason why the server slows down block placements after some time ? ... it all starts with 10k Blocks/s and now is going down to like 400 Blocks/s after 20min

[chrome beacon]

Is it loading chunks

[spiral light]

probably... but it has to load chunks all the time so no reason for slowing down after some time

[chrome beacon]

Maybe first chunks were generated

[spiral light]

hmm since i dont know how big the structure will be it will be bad to make Chunks persistent loaded for some time too
Chunks get unloaded after x time when nothing happens and no player in range right ?

Yeah

[undone axle]

Spoonfeed a newbie for a day and they'll come back with more questions. Teach them to find their own answers and you'll both be better off: you won't get stuck answering the easy questions and they'll be much more productive than before.

[chrome beacon]

?learnjava You should learn Java before starting

[undone axle]

Here are some links to get you started on learning Java:

• https://www.codecademy.com/learn/learn-java
• https://www.sololearn.com/learning/1068
• https://www.learnjavaonline.org/
• https://programmingbydoing.com/
• https://docs.oracle.com/javase/tutorial/java/index.html

The last one is the only official one, however some of those concepts assume that you already know a bit about programming.

[desert lagoon]

i now, But i only need this to fix. And i can contineu

[vocal cloud]

You can ask a question like "hey I'm having the issue x with code <link to pastebin with code> I've tried to do y,z but it's not working"

But don't ask for people to fix issues for you

[spiral light]

well... dont know how to code java but already using other API with even more complex things then spigot has ??

[crude charm]

dont continue

learn java

[desert lagoon]

https://www.toptal.com/developers/hastebin/vehopusevu.java

[crude charm]

?

[desert lagoon]

My Hastebin

[crude charm]

ok?

noone is going to help you

we told you what to do

[chrome beacon]

This is still the issue

[vocal cloud]

It's interesting to see how far along people can get with little to no java experience

[crude estuary]

If you Have an Issue Programming, you will Have more Even if Someone Fixes it for You

At least if Someone doesn't write for You the Whole Plugin

[crude charm]

...?

[crude estuary]

then we Have a Problem xD

i was talking to what they were Talking with Luca.

[vocal cloud]

wouldnt that just be contains?

what do you mean same word?

Do you mean regardless of case?

👍

[crude estuary]

It does by a lot, People tend to think that you can Learn to Code Minecraft Plugins without Learning Java

and it's a Bad Thing to do

If you Really want to Learn

xD

[fringe hemlock]

Yes

My code had 5 return trues in a row

[crude estuary]

xD, well, that Made you Learn Java First, Right?

[fringe hemlock]

Yes

And a couple reasons as well

[gleaming grove]

Guys is it possible to run a DataPack function (.mcfunction) by Spigot?

[crude estuary]

Just why?

[vocal cloud]

Better question what exactly do you want to do?

[visual tide]

seems like

?xy

[undone axle]

http://xyproblem.info/

[crude estuary]

True

[vocal cloud]

Heck yeah. Didn't realize we had that tag

[crude estuary]

It's so Cool to have the Command Directly

It's Needed lots of Times

xD

[gleaming grove]

because if so, i can do code in McFunction and it will be triggered by Client side, so server will be using less resources

[vocal cloud]

What exactly are you trying to do.

[gleaming grove]

i don't know yet, that's why im asking if its possible

[vocal cloud]

What? I can't tell you if something you don't even know you want to do is going to use less resources? It's like asking if bread will use less flour if I add more yeast yet when I ask how much yeast or flour you want to use you tell me you don't know yet.

[visual tide]

generally you want to do most actual "game" stuff to happen on the server, to minimize any messing by the client

and you usually dont have to worry that much about resources

[vocal cloud]

I assume that a datapack will not make the server use less resources anyways. Again, if you don't know what you plan to do then we can't give you any definitive answer

[visual tide]

sure you wouldnt load a 4gb file into memory but

[chrome beacon]

Datapacks are server side too

[tardy delta]

whats the point of setting fields to null when declaring them?

[chrome beacon]

They get initialized

[gleaming grove]

thank you

[tardy delta]

which they will do by default

[vocal cloud]

Fields being null allows you to null check them. So when an ItemStack doesn't exist instead of needing to check for a Material.AIR you can do if==null

[tardy delta]

no i mean like

[vocal cloud]

Yeah they're initializing it

We need a tag for https://tryitands.ee/

[tardy delta]

its like why would you do it

[gleaming grove]

{
    private MongoClient mongoClient;

    public Test()
    {

    }

    public initialDataBase(String name, String server)
    {
        mongoClient = new MongoClient(name,server);
    }

    public isDbInit()
    {
        return mongoClient != null;
    }

}

i hope this example is good explanation

[tardy delta]

its only initialized in a start method so its redundant to set it to null i guess

[gleaming grove]

yes, true

[gleaming grove]

maybe in this example the field is set to Null, to emphasize

[vocal cloud]

Usually you don't need to.

[hasty prawn]

It isn't always redundant. If you try accessing the object when it's not initialized it'll give you compile errors.

[quaint mantle]

Okay so I need a little help from yall, what event do I need to use if I want to see when an Item is being dropped.

It's for making items stack with custom name above them.

[gleaming grove]

https://www.spigotmc.org/threads/checking-dropped-item.187433/

[quaint mantle]

And is there a way to check it when I spawn it using .spawnItem?

[visual tide]

well check the type of the itemstack you spawned

[spiral light]

you can also call the PlayerDropItemEvent before your spawnItem method to handle everything in the event

[quaint mantle]

@EventHandler
    public void onPlayerItemDrop(PlayerDropItemEvent e){

        ItemStack item = ((Item) e).getItemStack();
        ((Item) e).setCustomNameVisible(true);
        ((Item) e).setCustomName("x"+((Item) e).getItemStack().getAmount() + " " + ((Item) e).getItemStack().getData().getItemType().name());
        
    }```

I use this, and when I drop the item, it won't set a custom name for it.

[chrome beacon]

That won't work

[buoyant viper]

so many things wrong there i think

[chrome beacon]

Yeah

[spiral light]

first: dont cast to Item 1000 times ...

[quaint mantle]

What's wrong?

[buoyant viper]

casting to Item each call

[spiral light]

also you cant cast the event to an Item ?

[chrome beacon]

^

You can't cast the ItemStack either

?learnjava I think this is needed

[undone axle]

Here are some links to get you started on learning Java:

• https://www.codecademy.com/learn/learn-java
• https://www.sololearn.com/learning/1068
• https://www.learnjavaonline.org/

• https://docs.oracle.com/javase/tutorial/java/index.html

The last one is the only official one, however some of those concepts assume that you already know a bit about programming.

[tardy delta]

why would something from that even work?

[quaint mantle]

Hmmm

[tardy delta]

dont you need itemstack instead of item

[spiral light]

probably copy paste and 0 knowledge about api

[vocal cloud]

Is the event registered?

[tardy delta]

if no errors probably not

[quaint mantle]

Thanks about that.

Now I know how Casting works.

[tardy delta]

i see

[quaint mantle]

Also, I use this and it works.

e.getItemDrop().setCustomName("test");
        e.getItemDrop().setCustomNameVisible(true);```

Show your build.gradle

[lean bone]

https://pastebin.com/gHRGPV0t This is it

The file that is linked ("libs/spigot-1.18.1.jar") is one I got from running buildtools

But it does not contain the NMS and CraftBukkit classes, which I need

[fringe hemlock]

I thought you were suppose to use the shaded jar for 1.18+

[chrome beacon]

You are

Which is why there is a problem

Actually since you're using gradle you shouldn't even use the jar

@lean bone ^^

[lean bone]

Then what should I use?

[vocal cloud]

Maven ✨

[buoyant viper]

compileOnly grrrr

[chrome beacon]

Use the dependency like you would normally. Just replace spigot-api with spigot

[lean bone]

Using the shaded JAR doesn't change anything

[chrome beacon]

It does

Try opening the jars and you will see the problem

[left swift]

Heyo! I am creating my own entity which consists of several armorstands. They have items on them. Is it possible to use EntityComplexPart for this? Ender dragon uses it. I can use it for my own entity or rather that's not possible.

[quaint mantle]

Cringe!

[sterile token]

Why Spigot.jar is single thread?

[lean bone]

compileOnly("org.spigotmc:spigot:1.18-R0.1-SNAPSHOT:remapped-mojang") I am using this now, but it cannot find it. Without the remapped-mojang it works, but I of course want to use the Mojang Mappings. I get the following error:

Searched in the following locations:
    https://repo.dmulloy2.net/repository/public/org/spigotmc/spigot/1.18-R0.1-SNAPSHOT/spigot-1.18-R0.1-20211130.174052-1-remapped-mojang.jar```

[spiral light]

better not... iirc it gets removed in newer versions

[sterile token]

What the difference between that jar and not remmaped one?

[chrome beacon]

Don't use remapped that won't work with gradle. There is no remapper

[quaint mantle]

You cannot use specialsource with gradle. Use paperweight instead

[chrome beacon]

^

[quaint mantle]

oops

[chrome beacon]

Will include paper api so becareful if you need spigot support

[quaint mantle]

hehehe

[chrome beacon]

One has method name like a() b() and the other nameForWhatThingsDo()

[hasty prawn]

Yes you can.

[lean bone]

I'd rather not use the PaperAPI because I don't like using the TextComponents everywhere (would also be a huge nightmare because this is for a project that I've been working on for about a year)

[chrome beacon]

Oh well unmapped it is

[quaint mantle]

damn thats sounds frustrating

[chrome beacon]

Or you know Maven

[quaint mantle]

pfff one day spigot will move to components anyway

[quaint mantle]

how

[chrome beacon]

Components > Strings

[quaint mantle]

^

[hasty prawn]

https://github.com/Dessie0/DessieLib/blob/master/build.gradle#L45

[quaint mantle]

Right, md_5?

[quaint mantle]

are you serious

[hasty prawn]

🤨

[quaint mantle]

https://github.com/jpenilla/special-gradle at least use this if you want remapeed spigot that much

[hasty prawn]

That's not the point lol

You said you can't use SpecialSource with Gradle, yes you can.

[quaint mantle]

but thats definetly a workaround

[hasty prawn]

How so? It's effectively doing the exact same thing the maven plugin does, and IS doing the same thing you would do manually.

Even md_5 said it was a good gradle config lol

[quaint mantle]

EvEn Md5

[hasty prawn]

Lmao alright

[sterile token]

lmao?

[quaint mantle]

okay, use this if you want

but i'd prefer

dependencies {
  paperDevBundle("1.18.1")
}

[sterile token]

That are the reasons of using Maven instead of Gradle

[quaint mantle]

Maven is cringe

[tender shard]

intellij weird

InventoryClickEvent.getClickedInventory is nullable

[sterile token]

Always btww

[vocal cloud]

Can't you click outside the inventory? That'd made the "clicked inventory" null?

[hasty prawn]

Yeah that's why IntelliJ is wrong

[tender shard]

maybe, but it's annotated with Notnull

[vocal cloud]

Oh mb

I can't read

[visual tide]

breh why

[vocal cloud]

[tender shard]

I'll find out when it returns null 😄

[sterile token]

We are using community version we cannot expect to much

[hasty prawn]

I think you mean Nullable

[sterile token]

🤔

[tender shard]

I have Ultimate

[sterile token]

Oh lol. If i have that problems i will prob do chargeback

[tender shard]

erm yes 😄

[visual tide]

well

big difference :kek:

[tender shard]

you can see this from the "Database" tab on the right 😛

[vocal cloud]

Intellij is p2w

[visual tide]

life is

[vocal cloud]

Life is play to win

[visual tide]

not really

[sterile token]

yeah, i prefer using community version but not using eclipse

That its more cringe than using Maven

[tender shard]

I only have ultimate because I get it for free every year

[visual tide]

:0

[sterile token]

Lol. You have because your university right?

Its really common on american universities that

[visual tide]

isnt alex german

[vocal cloud]

Love intellij giving me that free ulti

[tender shard]

yeah, you only need some university email address, it doesn't matter whether you university somehow supports it

all you need is a an email from an approvied uni

[tender shard]

yes

[vocal cloud]

Or documentation to back it up

[sterile token]

What you are german?

[tender shard]

and the best thing is: i can create as many email aliases as I want, so I can get stuff for free over and over again

[tender shard]

yes

[visual tide]

buys lvj.edu

[sterile token]

That shouldnt be ilegal?

[vocal cloud]

Just fake a document lmfao.

[tender shard]

I can create as many @wwu.de and @ uni-muenster.de emails as I want lol

[visual tide]

wha

dont you just get one assigned with your name and done

[sterile token]

In other words in intellij website no mattter the emails. If its a custom email you can use it

[tender shard]

yeah but we can add up to 5 aliases. and we can change them anytime to another one 😄

[visual tide]

oH

[sterile token]

😕

[visual tide]

u gonna make jetbrains broke

[sterile token]

Yeah. That why i asked if that was ilegal

🤔

[tender shard]

it's really a bit stupid

but awesome

[spiral light]

jetbrains networth is a lot more then mfnalex's networth 😄

[tender shard]

I think so too

[visual tide]

jesus christ 150€ a year

[spiral light]

too much

[tender shard]

yeah, getClickedInventory is null when clicking outside of it

someone should fix the javadocs

[spiral light]

i would switch to eclipse if i had to pay 150

[flat saddle]

hey

[vocal cloud]

I mean I'm definitely buying the entire suite after I'm done school

[flat saddle]

how can i get light block from command?

[visual tide]

also alex what when youre done at uni

[spiral light]

question for helper-server
if you want to know /give @p light ?

[flat saddle]

yes but m using cmi

[flat saddle]

oops sorry

[sterile token]

cmi?

[flat saddle]

essential like

[spiral light]

wow then use /minecraft:give @p light ?

[tardy delta]

^^

[sterile token]

if you the same command name you can do: pluginname:command

[flat saddle]

yeah i want to be supporter. But idk where to postulate

[tardy delta]

light_block?

look it up

[sterile token]

You can check on a website

I dont know the website name but its told you the ID of the item and the name

[tardy delta]

just google it

[spiral light]

still wrong channel .... but maybe your using wrong version

[tardy delta]

its light_block btw

[quaint mantle]

Is there a way to get an amount of how many items the dropped item contains ?

[tardy delta]

check the itemstack amount

[vocal cloud]

My man asking the learn java questions

[spiral light]

just no... ? at least for 1.18.1 its not light_block

[quaint mantle]

If you don't wanna help just dont say anything, it's that easy and simple.

[tardy delta]

idk google

[vocal cloud]

Because you're asking a question that with a basic understanding of java would avoid needing to be asked

[spiral light]

well its easy and simple if you would know how to use API and code java ...

[spiral light]

epic

[quaint mantle]

ig im retarded..

[vocal cloud]

You can use the docs of course but I'm lazy as heck

[tardy delta]

lmao

ItemsStack#getAmount

vs set

[vocal cloud]

No you just need to learn java first.

[quaint mantle]

do I need to learn the basics or ?

I know this is a dumb question.

But, what kind of level of java do you need to get into developing spigot plugins?

[vocal cloud]

Yes. Fundamentals first. You can always apply what you learn to spigot but it's got a learning curve that requires at the very least the fundamentals with a basic understanding of maven.

Or gradle.

It helps to know basic logging/debugging as well as it'll save you time here.

[quaint mantle]

Also one last question, did you use any shortcut to get the ItemStack class ?

The GIF that you sent.

[vocal cloud]

Ctrl + b

[tardy delta]

control click on itemstack

[vocal cloud]

Docs works just as well https://hub.spigotmc.org/javadocs/spigot/org/bukkit/inventory/ItemStack.html#getAmount()

[vocal cloud]

Using the mouse 🤮

[tulip owl]

I'd like to use the InteractiveBooks API, how would I add it to my pom.xml as it doesn't have a repo? I know need to add the jar locally but I have no clue how.

[tulip owl]

No maven repo either

[tulip owl]

Do i just run the command mvn install:install-file -Dfile=<path-to-file> -DpomFile=<path-to-pomfile>?

[vocal cloud]

That's the best way to do it

[tulip owl]

okay 👍

[vocal cloud]

If it's a maven jar

[sterile token]

I dont like the commands

[tulip owl]

gradle jar 😭 how would i do it then?

[sterile token]

I always use intellij interface. I dont really know abouts commands. I only know the mvn install, deploy

[tulip owl]

how would i add it in there?

[sterile token]

You have maven project right?

[tulip owl]

ive allways just edited the pom.xml by hand 🤣

[sterile token]

I always do that. I do it manually. I dont use commands

[tulip owl]

my project is maven, yes. jar im trying to add is gradle

[sterile token]

A gradle jar?

[tulip owl]

yea

[vocal cloud]

mvn install:install-file -Dfile=<path-to-file> -DgroupId=<group-id> -DartifactId=<artifact-id> -Dversion=<version> -Dpackaging=<packaging> this then

[tulip owl]

what is the packaging?

[sterile token]

yeah whats that?

I think if its pom jar

[vocal cloud]

Is it a jar or a war?

[tulip owl]

.jar file

[vocal cloud]

Gratz you answered your question

[tulip owl]

ah

[sterile token]

There 3 types i think: jar, pom, war

[tulip owl]

never heard of a war 🤣

[quaint mantle]

@vocal cloud sorry to bother you again, would you mind taking a moment to find a tutorial that you think is good for beginners ?

[vocal cloud]

If you don't mind basically reading boring crap read the oracle docs otherwise sign up for one of those free courses at like codeacademy

[vocal cloud]

It's for web applications hence the w. I use it for my spring API stuff on my Tomcat server

[tulip owl]

mvn install:install-file -Dfile=${project.basedir}/src/main/resources/InteractiveBooks.jar -DgroupId=net.leonardo_dgs -DartifactId=interactivebooks -Dversion=1.6.1 -Dpackaging=jar That errors when i run it, Unable to parse command line options: Unrecognized option: -inputFormat and there is no -inputFormat flag so i have no clue

[gleaming grove]

Do you know what is OOP (Class, Interface, Objects etc..)?

[tulip owl]

tbh, i just knew python and picked it up from java plugin video tutorials from kody Simpson

[quaint mantle]

wat

what are you trying to do

[tulip owl]

add a jar file to a maven project as a dependancy

has no repo

maven or gradle

[quaint mantle]

then clone the project and install it

[vocal cloud]

🤦‍♂️

[quaint mantle]

is interactivebooks actually opensource

[tulip owl]

yea

trying to use thier API

[visual tide]

jitpack then

[quaint mantle]

jitpack cringe!

[vocal cloud]

Wait I thought you had the jar because it wasn't open source

[tulip owl]

no gradle repo to go from

[vocal cloud]

Give me a link to their repo

for the API

[tulip owl]

https://github.com/Leonardo-DGS/InteractiveBooks/wiki/API-Usage

same as the main one (i think)

[vocal cloud]

Sigh.

Hello, the code kinda works, but than I type random thing (not online player in arg1) it just gives me an error ```

if (p.hasPermission("admin.permission")) {
if (args.length == 0) {
p.sendMessage("Command usage: /test <player>");
} else if (args.length == 1) {
if (Objects.requireNonNull(Bukkit.getPlayer(args[0])).isOnline()) {
p.sendMessage("It's working!");
} else {
p.sendMessage("Player not found");
}
}
}
}
}
return true;
}````

[tulip owl]

Where does it save the import? Like i don't see any change on the pom.xml

[quaint mantle]

check if play is null instead of isOnline

[vocal cloud]

To your maven dependencies

[tulip owl]

so won't gh actions not be able to build it?

[vocal cloud]

You're using intellij aren't you?

[rich creek]

Hi, I have a question.
Is there any way I can make my Plugin update at 00:00 AM?

[worthy scarab]

Yes I do

[tulip owl]

as that is my pc's deps, right? Or am i confusing it

[vocal cloud]

Yes.

[vocal cloud]

You saw this and used intellij auto fix right?

[tulip owl]

sooo, how would i save it as a dependency inside the project file? As i want anyone to be able to build it

[vocal cloud]

Without reading up on what Object.requireNonNull actually does.

[worthy scarab]

nop, there's nothing like this

[vocal cloud]

Objects.requireNonNull(Bukkit.getPlayer(args[0])).isOnline() this is in your code right?

You obviously used intellij's code analysis tool to fix your issue. Which says to use Objects.requireNonNull.

[vocal cloud]

You'd want to include it as a local repo. Which is different

[tulip owl]

ah, how would i do that?

[vocal cloud]

Never done it before. Something like this I imagine https://stackoverflow.com/questions/2229757/maven-add-a-dependency-to-a-jar-by-relative-path

[tulip owl]

Won't i run in to issues with slashes and backslashes in paths on windows/linux, thus actions can't build it or i can't build it

[vocal cloud]

I mean you tell people to install it manually in order to modify your code. Maven was made for repos hosted elsewhere not really for local jar files.

[tulip owl]

true, would i be able to host a repo myself?

or would the plugin dev have to do that

[vocal cloud]

You could host it yourself. Fork it and switch it to maven

[tulip owl]

ah

[ashen vessel]

Havent built a plugin in the new java and maven is throwing the classic invalid target release, any help?

[tulip owl]

could jitpack do that?

[visual tide]

i dont get why you cant just normally use jitpack

[vocal cloud]

Yes Objects.requireNotNull produces an error. Which is the intended mechanic. Stop using it if you don't want the error

[buoyant viper]

oh yeah local file dep without adding to local repo is always fun

[vocal cloud]

https://jitpack.io/#Leonardo-DGS/InteractiveBooks build failed

[visual tide]

oH

use https://jitpack.io/#Leonardo-DGS/InteractiveBooks/-SNAPSHOT then

[quaint mantle]

(shitpack)

[tulip owl]

wait THAT EXISTS

[vocal cloud]

That's kinda dangerous if it gets updated with beta features often tho. 🤷‍♂️

[visual tide]

eh

[tulip owl]

why do they not link that in their wiki 😭

[visual tide]

take the risk

[tulip owl]

yea

[visual tide]

if you want

[tulip owl]

i will

[visual tide]

what u got against it 😦

ew lombok

[vocal cloud]

Only use as a last resort

[visual tide]

i mean yes but its quick and easy

[vocal cloud]

Yes now send the error

[tulip owl]

if it works, the -SNAPSHOT builds can't be found

[vocal cloud]

Either fork it and move it to maven or just install it locally

[visual tide]

https://jitpack.io/#Leonardo-DGS/InteractiveBooks/859098f6cb then

[quaint mantle]

the best way

[visual tide]

jesus christ

[vocal cloud]

JitPack aneurism man.

Your super power is finding JitPack builds to use until you eventually you go into anaphylactic shock

[tulip owl]

oh, i havent used jitpack in this project yet so the repo wasn't added

[worthy scarab]

@vocal cloud Cannot invoke "org.bukkit.entity.Player.isOnline()" because the return value of "org.bukkit.Bukkit.getPlayer(String)" is null

Bingo.

This is a learn java moment fr

Do a null check of player before using it. Problem solved

Trying to compile plugin, and maven spits out "invalid target release 17.0.1". Just updated to Java 17 and I already set the JAVA_HOME env variable.

idk why it's looking in the paper repo for it's build?! well anyway it's not finding it in there

[visual tide]

did you add the jitpack repo

[tulip owl]

yea

[visual tide]

yeet caches and try again

[tulip owl]

mvn clean install -U?

if so, I did that

[visual tide]

i meant in ur ide

[tulip owl]

how? I use IntelliJ

[vocal cloud]

What do you run to get the error? Package?

[ashen vessel]

My build command line is clean install

Idk what else to answer with. My knowledge isnt 100% with java/spigot

[vocal cloud]

I'd use package but w/e. Are you using intellij?

[midnight glade]

Is there any way to let players do commands and whatnot without them having to be Op or using a permissions plugin?

[vocal cloud]

Have no permissions for the command?

[tulip owl]

permissions.yml?

or that

[midnight glade]

There's already no perms set, it says I need permission to use the command

Basically just a raw hello world test

[tulip owl]

How would i do that in intellij?

[vocal cloud]

[visual tide]

file > invalidate caches

[tulip owl]

ty

[vocal cloud]

Just tested it you don't need permissions for commands by default.

[midnight glade]

Also I'm making a team based game mode, what is the best way to test? Do people really just buy multiple accounts?

[vocal cloud]

That looks like paper. We're spigot here

[midnight glade]

Even with that switching accounts is very annoying no?

[vocal cloud]

👀

[midnight glade]

Oof guess I'll go buy a bulk pack of cracked Minecraft accounts

[vocal cloud]

lul jokes aside you could just use offline mode or something.

[midnight glade]

I mean go buy a new account from mojang

[vocal cloud]

Albeit you'd need to do more work

[quaint mantle]

Wht not just offline mode? It is fine and meant to be used for dev purposes

[midnight glade]

I'll take a look

I've never touched chest data

Do chests know who built them

Or do locking chestings require you to store that data yourself?

[vocal cloud]

Things like locking chests require a player to have either placed it when the plugin was active or used some method of locking it via command

[midnight glade]

Hmm is there chest IDs?

I assume there has to be

[vocal cloud]

When it's placed? No.

[midnight glade]

Not when placed the concept is if someone on the team dies the entire teams associated chests are emptied

I'll just store the cheat IDs in their config file

Assuming it exists

[vocal cloud]

Use memory/db not a config. I mean you can use the PDC to store it as well

However, you still need a method of finding the chest so it's best to store it's location in a database of sorts

[midnight glade]

Database isn't needed

It would likely take longer to parse it in a JSON or XML file than it would be to get a list off of the teams specific cfg file

[hasty prawn]

I mean you can use any way you want to store the data, but the only unique ID a chest has is it's location afaik.

[midnight glade]

Yeah that's what I was wondering

[quaint mantle]

Not really, but I'm willing to learn and spend time learning java, because I find it good, and fun coding with it.

I'm going to sign up to one of the courses right now and start learning it bit by bit, so I won't be a dumbass and ask questions that are self explanatory.

[ashen vessel]

Yes

[spiral light]

dont pay money to learn java pls O.o

[quaint mantle]

There's everything you need online, for free.

[vocal cloud]

Does intellij recognize the java 17 SDK

[ashen vessel]

Probably not. Where can I change that

[quaint mantle]

Just like I learned JS, I'll learn java, it'll just take a little longer since it's harder of a language.

[spiral light]

ok just because your wrote "sign up" ... always sounds like register and pay

[gleaming grove]

so jump to google or youtube and find answers to those question, i think this is solid start for doing anything in java what is List what is ListArray what is HashMap what is "new" <- most important what is object what is Class what is Interface

[vocal cloud]

ctrl+alt+shift+s

[vocal cloud]

I mean a structured free course is better than learning everything from google

[ashen vessel]

Yeah thatll prob do it

[quaint mantle]

The order is broken

[ashen vessel]

Alright so I changed it but same problem

[gleaming grove]

i guess, if you have some course just put the link

[quaint mantle]

Im a baeldung gigachad

[vocal cloud]

Same

[vocal cloud]

I mean you've got https://www.codecademy.com/learn/learn-java. Teaches all of the basics and tests said knowledge.

[vocal cloud]

Whats the maven directory

[ashen vessel]

It doesnt let me post screenshots here

[vocal cloud]

Is it bundled or

[ashen vessel]

Yes

bundled

V3.6.1

[vocal cloud]

Hmmmm. I've never had the issue of invalid target release from bundled. I also have 1.8 as my home and it still works for 16-17 etc

[vocal cloud]

Do you use this to package your jars?

[ashen vessel]

No

[vocal cloud]

I wonder if that will do it.

Intellij usually figures out what version of java you want to use

[ashen vessel]

clean install has always worked for me but let me try that

Same problem

[vocal cloud]

Wait did you change your JAVA_HOME variable to 17?

[ashen vessel]

Yeah

The directory

[vocal cloud]

Did you restart intellij and such after doing so?

[ashen vessel]

No

After restarting it still dont work

I swear intelliJ hates me

[vocal cloud]

And you changed PATH as well?

[quaint mantle]

You know it shouldnt be a number right

[ashen vessel]

All I changed was JAVA_HOME to the directory for Java 17 under System variables

[ashen vessel]

Ah

[vocal cloud]

this is for CLI so idk if it affects maven at all

although my default is 17

and I have 1.8 on both path and java_home 🤡

besides rebooting I'm fresh out of ideas lol. When you use cmd and run java --version what does it output

[ashen vessel]

java 17.0.1

[vocal cloud]

Idk I'm stumped.

Maybe just throw the whole maven error into a pastebin

Send it over

[sage patio]

Hi, I'm working on a project needs Minecraft 2 clients for test, also I have a low end pc and I can't open 2 clients at same time, any ideas ?

[vocal cloud]

Get a friend

[sage patio]

Big brain, its on LocalHost

[vocal cloud]

Open port then have a friend

[tender shard]

or grab some cheap server from a provider

[vocal cloud]

Change MC parameters to run as poorly as possible.

Buy 128GB of ram and use thishttps://github.com/mkrupczak3/jvmperfopts

[sage patio]

both ideas are so nice, but I have a bad internet & no money

[vocal cloud]

Well I mean you're SOL if you can't run 2 clients. There's nothing you can do besides running them on the minimum java arguments

[sage patio]

good thanks

[tender shard]

• optifine + view distance 4

lol

superflat world also helps performance

[ashen vessel]

https://paste.md-5.net/axiketubat.sql

[tender shard]

you have set your target release to 17.0.1

just set it to 17

[vocal cloud]

Yeah was going to say that. Try 17

[tender shard]

@ashen vessel

[ashen vessel]

Thats what I did originally

[vocal cloud]

Albeit mine works with that exact version

[tender shard]

use 17 again and show us the new error that it throws 😄

[ashen vessel]

https://paste.md-5.net/horozipogu.sql

👍

[vocal cloud]

Ohh a different error

[tender shard]

you must use java 17 to run it

[vocal cloud]

No we're getting somewhere

[tender shard]

oh wait you did

wait

[ashen vessel]

Lol

[tender shard]

the shade plugin

is your problem

maven shade 3.2 doesnt support java 17

[ashen vessel]

Dont even know what that is

[tender shard]

you need to use maven shade 3.3.0-SNAPSHOT

you also need the snapshot repository to use it

send your full pom pls

I'll send back a fixed pom

[ashen vessel]

Thx

[hasty prawn]

🥄

[tender shard]

well it's just a pom lol

[hasty prawn]

yeah ik dw lol

[ashen vessel]

?

https://paste.md-5.net/azuzariqev.xml

[vocal cloud]

Found their pom https://paste.md-5.net/epejifegup.xml

I think

[ashen vessel]

Old one

[vocal cloud]

Ah

Well there u go

[tender shard]

so first, we'll add this

<pluginRepositories>
  <pluginRepository>
    <id>apache.snapshots</id>
    <url>https://repository.apache.org/snapshots/</url>
  </pluginRepository>
</pluginRepositories>

[ashen vessel]

Does it matter where?

[tender shard]

and then set maven shade plugin to 3.3.0-SNAPSHOT

inside <project>, ill send it in a minute

[ashen vessel]

Ok

I should be able to figure it out

[tender shard]

https://paste.md-5.net/juhelulezo.xml

i added the plugin repo at the very bottom

[vocal cloud]

Weird 3.2.4 works for me

[tender shard]

because the stuff you shade isnt java 17

maven shade 3.2.4 works fine on java 17 but it cannot shade classes compiled for java 17

[ashen vessel]

Shade throws a warning but there is a successful build. To be fair I was using a year or two old pom file

[vocal cloud]

?paste

[undone axle]

https://paste.md-5.net/

[vocal cloud]

So this wouldn't work? https://paste.md-5.net/iwimisulup.xml or am I misreading lol

[tender shard]

yes sure

as long as none of your depenencies requires java 17

you'll see whether it works by getting an error or not 😄

[tender shard]

what warning?

[vocal cloud]

I was trying to replicate it never thought to change the deps

sigh

[ashen vessel]

  - META-INF/MANIFEST.MF
maven-shade-plugin has detected that some class files are
present in two or more JARs. When this happens, only one
single version of the class is copied to the uber jar.
Usually this is not harmful and you can skip these warnings,
otherwise try to manually exclude artifacts based on
mvn dependency:tree -Ddetail=true and the above output.
See http://maven.apache.org/plugins/maven-shade-plugin/

[tender shard]

that doesn't matter at all

[ashen vessel]

I figured

[tender shard]

if you want to get rid of it, you can exclude the META-INF from the shaded artifacts

you only have to worry about META-INF if you build a standalone application. for plugins, it is not needed at all

[ashen vessel]

Alrighty

[vocal cloud]

Maven making me mad

[tender shard]

why?

[vocal cloud]

Idk it's an alliteration

[worthy scarab]

Impossible to import a string or something like that from one class to another?

[tender shard]

import?
