Hello! I'm trying to do my first mod (in 1.15.2) and I've got a little problem...

When I try to run Minecraft from Eclipse, it crashes! 

Here's the log

---- Minecraft Crash Report ----
// I bet Cylons wouldn't have this problem.

Please, Help me ! I'm new and I have no idea what to do to resolve this.

 

package com.leolerenard.foxfantasy;

import net.minecraftforge.common.MinecraftForge;
import net.minecraftforge.eventbus.api.SubscribeEvent;
import net.minecraftforge.fml.common.Mod;
import net.minecraftforge.fml.event.lifecycle.FMLClientSetupEvent;
import net.minecraftforge.fml.event.lifecycle.FMLCommonSetupEvent;
import net.minecraftforge.fml.event.server.FMLServerStartingEvent;
import net.minecraftforge.fml.javafmlmod.FMLJavaModLoadingContext;

@Mod("foxfantasy")
public class FoxFantasy {
    public FoxFantasy() {
        FMLJavaModLoadingContext.get().getModEventBus().addListener(this::setup);
        FMLJavaModLoadingContext.get().getModEventBus().addListener(this::doClientStuff);

        MinecraftForge.EVENT_BUS.register(this);
    }

    private void setup(final FMLCommonSetupEvent event) {

    }

    private void doClientStuff(final FMLClientSetupEvent event) {

    }

    @SubscribeEvent
    public void onServerStarting(FMLServerStartingEvent event) {

    }
}

Here's the .java file

 

Based off the crash report, it seems like there's something wrong with the listeners for your event bus. I don't know too much about modding in this version though so sorry if I couldn't be more help.

Edited by outflows

Use Java 8 for modding.

I'm eager to learn and am prone to mistakes. Don't hesitate to tell me how I can improve.
