ExampleMod.java file:

package com.Arnox.ExampleMod;

import net.minecraftforge.common.MinecraftForge;
import net.minecraftforge.fml.common.Mod;
import net.minecraftforge.fml.event.lifecycle.FMLClientSetupEvent;
import net.minecraftforge.fml.event.lifecycle.FMLCommonSetupEvent;
import net.minecraftforge.fml.javafmlmod.FMLJavaModLoadingContext;
import org.apache.logging.log4j.LogManager;
import org.apache.logging.log4j.Logger;

// The value here should match an entry in the META-INF/mods.toml file
@Mod("exmod")
public class ExampleMod
{
    // Directly reference a log4j logger.
    private static final Logger LOGGER = LogManager.getLogger();

    public ExampleMod() {
        // Register the setup method for modloading
        FMLJavaModLoadingContext.get().getModEventBus().addListener(this::setup);
        // Register the doClientStuff method for modloading
        FMLJavaModLoadingContext.get().getModEventBus().addListener(this::doClientStuff);
        // Register ourselves for server and other game events we are interested in
        MinecraftForge.EVENT_BUS.register(this);
    }

    private void setup(final FMLCommonSetupEvent event)
    {
        // some preinit code
    }

    private void doClientStuff(final FMLClientSetupEvent event) 
    {
        // do something that can only be done on the client
    }
}

 

As  you can see, there isn't anything here at all. Yet, even though there's only these two files, no matter what I do, I can't get it to run properly. There is no "examplemod" modid anywhere in these files, and yet, it still complains about it. For the love of everything, please help me get this to work. This is insanely frustrating. I haven't even written anything yet.

 

Working on 1.16.1, Forge version 32.0.106. Using the Eclipse Java IDE, AdoptOpenJDK 8.0.265.01-Hotspot, and JRE 1.8.

I also took the time to replace all instances of "examplemod" (lowercase only) as well with "exmod". Still no difference.

A small bit of good news. Looking through the console log, I found this:

 

Quote

[m[36m[10:27:33] [pool-2-thread-1/DEBUG] [ne.mi.fm.lo.mo.Scanner/SCAN]: Scanning C:\Users\User1\Desktop\minecraftTestMod\build\resources\main with language loader javafml

[m[36m[10:27:33] [pool-2-thread-1/DEBUG] [ne.mi.fm.ja.FMLJavaModLanguageProvider/SCAN]: Found @Mod class com.example.examplemod.ExampleMod with id examplemod

 

I have no idea where the hell it's finding that though. There's nothing in the above directory besides mods.toml and pack.mcmeta. The plot thickens too when I build the project and then look into the libs folder, open "modid-1.0.jar" and then I get this:

 

com

      Arnox

            examplemod

                  ExampleMod.class

      example

                  ExampleMod$RegistryEvents.class

Show the package explorer in your IDE please

Here you go:

 

[Beethoven92]

You should also change those in your build.gradle

Quote

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

to the values specific to your mod. If you use "exmod" as your modid, your package name also has to reflect that. So, your com.arnox.ExampleMod should become com.arnox.exmod (you should really put your package names all in lowercase). So change the 'group' and 'archivesBaseName' fields respectively with 'com.arnox.exmod' an 'exmod'. Setup your build.gradle again after changing anything inside it to refresh it with the new values

Refactored com.Arnox.ExampleMod to com.arnox.exmod.

 

Edited the specified part in the build.gradle file to this:

version = '0.0.1'
group = 'com.arnox.exmod' // http://maven.apache.org/guides/mini/guide-naming-conventions.html
archivesBaseName = 'exmod'

 

Executed the build setup "init" and "wrapper" gradle tasks.

 

Still erroring out with the same error.

 

Assembled jar file (exmod-0.0.1) now looks like this:

com

      Arnox

            exmod

                  ExampleMod.class

            examplemod

                  ExampleMod.class

      example

            examplemod

                  ExampleMod$RegistryEvents.class

                  ExampleMod.class

      MANIFEST.MF

      mods.toml

Sorry, by "setup your build.gradle" i meant, re run genEclipseRuns. Should have specified that

Done. Still erroring out with the same error. Jar still has the same folders and files as listed in the last post.

 

More and more, I'm starting to think this is a gradle bug or something.

Just simply delete the whole example directory in your main directory it should fix it, you won't need that directory anyway

In the src/main/java directory? I'm afraid there's only what is shown in the screenshot. src/main/java/com/arnox/exmod/ExampleMod.java to be exact.

[Beethoven92]

At this point, maybe just starting a new fresh project would be a good idea, and see if the problem still appears

Sorry i didn't see your pic i only read the first and last comment to see if you was able to solve this issue. I usually setup a new directory rather than using the Example one that's why i said to just delete it.

[Arnox]

Deleted and reinstalled Eclipse entirely. Deleted the entire project files and redownloaded them (1.16.2 this time). Imported the Gradle Project. Did a test Client run before editing. Works just fine. Edited the package name to "com.arnox.exmod". Edited the modid in the ExampleMod.java file and all the modid's in the mods.toml file.

 

Still errors out in the exact same way.

 

Editing the build.gradle file to remove examplemod and then rerunning genEclipseruns and then another test Client run STILL gives the same error. Guys, I really think this is a bug...

 

EDIT: I tried just deleting the original mod package wholesale and creating it entirely from scratch (com.arnox.exmod2) and copied the contents of the old Java file to the new one. STILL THE SAME ERROR. WHAT THE HELL? It always sees com.example.examplemod. It never goes away! Please tell me other people are getting this error too.

Show the contents of the "bin" folder? It might be that eclipse is duplicating the examplemod from a sourceset somewhere.

Try running "gradlew clean eclipse genEclipseRuns" and then refresh your gradle project (F5 when selecting project in package viewer)

[hiotewdew]

It's also possible the examplemod is somehow included in the classpath. Check "Project and External Dependencies", your "run/mods" folder, and the build path (rclick project and external dependencies -> Build Path -> Configure Build Path... look for examplemod

FINALLYYYYYYYYY

 

The Hell is over. It's done. It works now. Finally... Thank you so much. ❤️

 

I guess my only question now is... Why is the command different when I run it in the command prompt as opposed to in the IDE?
