How do you add it into classpathm

[wintry plover]

do u mean build.gradle?

[slow charm]

Yea

[wintry plover]

dependencies {
    implementation 'com.github.pemistahl:lingua:1.2.2'
}

buildscript {
    repositories {
        maven {
            name = "forge"
            url = "https://files.minecraftforge.net/maven"
        }
    }
    dependencies {
        classpath 'net.minecraftforge.gradle:ForgeGradle:2.1-SNAPSHOT'
    }
}

do i need to add another classpath for it

in my buildscript

[minor sandal]

it sais caused by NullPointerException

Can you show that part of the stack trace as well?

and the corresponding code

is there a static block?

[wintry plover]

No

[wintry plover]

yes 1sec

this is everything it says when it errors

final Language english = Language.ENGLISH;

this is the code that makes the error

because its trying to access the Language class

import com.github.pemistahl.lingua.api.Language;
import com.github.pemistahl.lingua.api.LanguageDetector;
import com.github.pemistahl.lingua.api.LanguageDetectorBuilder;

[minor sandal]

Are there really no logs after that?

[wintry plover]

yes

[minor sandal]

Can you show the Language class?

[wintry plover]

the full code of it?

[minor sandal]

And can you also show checkCmd and mark where line 39 is?

oh, it's Kotlin

[minor sandal]

Can you add the following try-catch instead of that line for testing?

Language english;
try{
  english = Language.ENGLISH;
}catch(Throwable e){
  e.printStackTrace();
  throw e;
}

[wintry plover]

yes ill do that

[minor sandal]

that should probably result in more logs

Can you please show them here?

[wintry plover]

this time it gave class not found error before I ran the command

[minor sandal]

oh so it seems like System.err is set to something else

WTF is Minecraft doing

[wintry plover]

idk 😭

[minor sandal]

try that instead:

Language english;
try{
  english = Language.ENGLISH;
}catch(Throwable e){
  try(PrintStream ps = new PrintStream("PATH/TO/SOME/FILE.log")){
    e.printStackTrace(ps);
  }
  throw e;
}

where you should replace PATH/TO/SOME/FILE.log with the path to some nonexisting file that you can open.
The code should then create that file and write the actual stack trace to that file.

(I edited the code, I forgot something important)

I think it doesn't like something in the Language class but the stack trace is weird so I'd want to see what exactly is there

[wintry plover]

i dont think I can do PrintStream

im stuck on language level 6

its giving me a lot of errors

it does NOT like that code

[wintry plover]

earlier I built the jar and checked the latest.log file when it errored but it gave the same stack trace

[minor sandal]

PrintStream was there before Java 6

[slow charm]

wow FG 2.1

[minor sandal]

oh you are throwing CommandException

[slow charm]

thats like prehistoric modding xd

[minor sandal]

try replacing the Throwable e with Error e

Language english;
try{
  english = Language.ENGLISH;
}catch(Error e){
  try(PrintStream ps = new PrintStream("PATH/TO/SOME/FILE.log")){
    e.printStackTrace(ps);
  }catch(IOException e1){
    e1.printStackTrace();//we are throwing the original exception anyways 
  }
  throw e;
}

Note that this code is just for testing/diagnosing the issue

[minor sandal]

I have no idea what that means or about Minecraft modding in general. If you know how to solve this, feel free to say so xd

[wintry plover]

😭

im modding 1.8.9

idk if that relates to what language levels im allowed to use

but ive tried upgrading it before but it just resets it back to 6

when I build

Language english;
        try{
            english = Language.ENGLISH;
        }catch(Error e){
            try {
                PrintStream ps = new PrintStream("PATH/TO/SOME/FILE.log");
                try {
                    e.printStackTrace(ps);
                } finally {
                    ps.close();
                }
            } catch(IOException e1){
                e1.printStackTrace();//we are throwing the original exception anyways
            }
            throw e;
        }

does this look right?

well once I change the path

[minor sandal]

yes

[minor sandal]

Didn't that run on Java 8?

[wintry plover]

yes im using java 8

[minor sandal]

I think you probably need to change it in your pom.xml/build.gradle

[minor sandal]

Java 8 <==> language level 8

[wintry plover]

ohh

wait lemme try that then

[minor sandal]

But I think you configured something else in your pom.xml/build.gradle

Because if you want to change the language level/Java version, you need to do that there

[wintry plover]

<bytecodeTargetLevel target="1.6" />

is it this?

[minor sandal]

yes

Are you using ant?

(this would be the case with a build.xml)

[slow charm]

they should be using gradle

[wintry plover]

im using gradle

[slow charm]

the forge tooling is literally called ForgeGradle

[slow charm]

can you post your buildscript

[wintry plover]

buildscript {
    repositories {
        maven {
            name = "forge"
            url = "https://files.minecraftforge.net/maven"
        }
        mavenCentral()
    }
    dependencies {
        classpath 'net.minecraftforge.gradle:ForgeGradle:2.1-SNAPSHOT'
    }
}

[slow charm]

buildscript i mean the entire build.gradle

[wintry plover]

oh ok

// For those who want the bleeding edge
buildscript {
    repositories {
        maven {
            name = "forge"
            url = "https://files.minecraftforge.net/maven"
        }
        mavenCentral()
    }
    dependencies {
        classpath 'net.minecraftforge.gradle:ForgeGradle:2.1-SNAPSHOT'
    }
}
apply plugin: 'net.minecraftforge.gradle.forge'

version = "1.0"
group= "com.yourname.modid" // http://maven.apache.org/guides/mini/guide-naming-conventions.html
archivesBaseName = "modid"

minecraft {
    version = "1.8.9-11.15.1.2318-1.8.9"
    runDir = "run"
    mappings = "stable_20"
}

dependencies {
    implementation 'com.github.pemistahl:lingua:1.2.1'
}

processResources
{
    inputs.property "version", project.version
    inputs.property "mcversion", project.minecraft.version

    from(sourceSets.main.resources.srcDirs) {
        include 'mcmod.info'

        expand 'version':project.version, 'mcversion':project.minecraft.version
    }

    from(sourceSets.main.resources.srcDirs) {
        exclude 'mcmod.info'
    }
}

[slow charm]

hmm this doesnt work?

try using compile configuration

[minor sandal]

idk about that Minecraft stuff but changing <bytecodeTargetLevel target="1.6" /> is probably a good start - and there's probably also a source level you need to change

[slow charm]

instead of implementation

[minor sandal]

Oh I just realized that Language isn't even your class

[slow charm]

its a library

they probably provided it wrongly to the toolchain

also

to change java version

[wintry plover]

ill try that

i remember having it compile before but it told me to change to implementation

[slow charm]

hmm?

okay then show me the error

also to specify java version, you should be able to this inside the buildfile

[minor sandal]

Ok that more information. It tells you that the NPE occurs in LaunchClassLoader, specifically line 182

[wintry plover]

okay I changed it to compile

and it didnt error this time

[slow charm]

great

[wintry plover]

let me try printing the language.name

[wintry plover]

just checking, that lets me go to a higher language level?

[slow charm]

well you set it to 1.8 iirc

try it

look into some example mod configs

https://github.com/Alexdoru/ExampleMod1.8.9/blob/master/build.gradle

[wintry plover]

yea i think it worked

it didnt reset it back to 6

tysm!

[slow charm]

glad i helped

[wintry plover]

crazy how just changing implementation to compile fixed the entire problem

[slow charm]

well the reason is that forgegradle is checking for all libraries marked as compile to include in jar

implementation isnt being checked on by FG, therefore it was not included and caused ClassNotFound on runtime

[wintry plover]

ah ok

what does FG stand for

forge gradle

[slow charm]

yes

the toolchain forge uses

[wintry plover]

thats weird because the whole reason i changed it from compile to implementation in the first place

was because it told me to

ages ago

[slow charm]

are you sure you didnt put it into buildscript { dependencies { here } }

[wintry plover]

yes

[slow charm]

then idk

[wintry plover]

unless im remembering wrong idk

im just glad its working now
