Bukkit.getScheduler().runTask(BattlePlugin.getPlugin(), () -> {
                            var config = TeamConfigWrapper.toTeamConfig(TeamConfigSerializer.loadData());
                            var battleData = getBattleData(name, category);
                            Bukkit.getPluginManager().callEvent(new BattleStartedEvent(config, battleData));
                        });

The event

#


    @Override
    public void onEnable() {
        // Plugin startup logic
        Bukkit.getLogger().info("HookPlugin - started!");
        Bukkit.getPluginManager().registerEvents(this, this);
    }



    @EventHandler
    public void listenTest(BattleStartedEvent ddos) {
        Bukkit.broadcastMessage("Received start");
    }```

The foreign plugin

#

I also had a separate event listener class but same result of not being present on the server as registered listener.

BlockPlaceEvent for example is called fine from this class

#

can you show the error ?

west ember Jul 17, 2023, 1:37 PM

#

There is no error logged as far as I am aware, at least not into console. It is just not present

silent tendon Jul 17, 2023, 1:38 PM

#

then i dont understand the problem rightr

west ember Jul 17, 2023, 1:40 PM

#

The listener from TestPluginHook is not called at all, which is a separate plugin. Only Listeners from the plugin that calls the event are called.

#

This prevents me from being able to create addon plugins for my main plugin that are easily expandable

silent tendon Jul 17, 2023, 1:41 PM

#

how does the extend plugin looks like ?

west ember Jul 17, 2023, 1:41 PM

#

#1130491625748058162 message It's just this atm

silent tendon Jul 17, 2023, 1:42 PM

#

and the plugin runs correctly ?

west ember Jul 17, 2023, 1:42 PM

#

it is called, the on enable is logged into the server

silent tendon Jul 17, 2023, 1:42 PM

#

and in the schedular calling the event works too ?

west ember Jul 17, 2023, 1:42 PM

#

yes

#

other listeners to the event are notified

#

https://github.com/JoKrus/dj-battle-plugin/blob/master/src/main/java/net/jcom/minecraft/battleplugin/handler/BattleApiHandler.java

This one as an example, and I don't do anything different there

GitHub

dj-battle-plugin/src/main/java/net/jcom/minecraft/battleplugin/hand...

#

So my guess was/is that the reason that the TestPluginHook one is in a separate jar and I need to do something different there

you can take a look here: https://www.spigotmc.org/wiki/using-the-event-api/

#

That's exactly what I do

#

But for some reason TestPluginHook Handler is not present as registered listener when calling the event even though registerEvents is called and no error gets logged

silent tendon Jul 17, 2023, 1:47 PM

#

you could check the Handler List if it gets modified or smth added to it

west ember Jul 17, 2023, 1:48 PM

#

how would I do that exactly? I tried a breakpoint there but got overwhelmed by the amount of calls

silent tendon Jul 17, 2023, 1:48 PM

#

there are methods on HandlerList-Obj tto chheck how many things are registered i guess

west ember Jul 17, 2023, 1:56 PM

#

It gets registered also... but there is also only 1 listener registered

#

so it seems that for some reason my class has 2 existences since BattleStartedEvent.getHandlerList() returns different handlerslors map on each plugin

silent tendon Jul 17, 2023, 1:58 PM

#

do you have 2 classes of the same name?

#

BattleStartedEvent.getHandlerList() should not return different handler maps

west ember Jul 17, 2023, 2:01 PM

#

seems like it, trying to compare the class objects of the eventClass of the executor right now

#

both log the exact same class, getHandlerList and getHandlers return the same static HandlerList field

#

I have no clue anymore

#

For some reason the events are still registered separately

silent tendon Jul 17, 2023, 2:08 PM

#

dependency correct ?

#

import correct ?

#

what if you remove the event-owening plugin

west ember Jul 17, 2023, 2:09 PM

#

silent tendon what if you remove the event-owening plugin

No difference sadly

silent tendon Jul 17, 2023, 2:11 PM

#

can you create the event at onEnable on the extending plugin ?

#

this should at least work or throw exception

west ember Jul 17, 2023, 2:12 PM

#

Found the issue

#

It was indeed 2 instances

#

I provided the reproducable thingy the api with <scope>provided</scope> and now it works

#

so there really seemed to exist 2 different classes, maybe ecause they were living in different modules and then the add on plugin matched this instead?

#

Not that deep into java logic

#

Thanks a lot for your help mate!
