java.lang.ClassNotFoundException Mod Class Not found :S

[Grosso10]

Helloo!

I am trying to launch my first mod, the mod class looks like this:

 

package com.ignasi.tutorial;

 

import com.ignasi.tutorial.init.TutorialItems;

import com.ignasi.tutorial.proxy.CommonProxy;

 

import net.minecraftforge.fml.common.Mod;

import net.minecraftforge.fml.common.Mod.EventHandler;

import net.minecraftforge.fml.common.Mod.Instance;

import net.minecraftforge.fml.common.SidedProxy;

import net.minecraftforge.fml.common.event.FMLInitializationEvent;

import net.minecraftforge.fml.common.event.FMLPostInitializationEvent;

import net.minecraftforge.fml.common.event.FMLPreInitializationEvent;

 

@Mod(modid = Reference.MOD_ID, name = Reference.MOD_NAME, version = Reference.VERSION, dependencies = "required-after:FML")

public class TutorialMod {

 

@Instance(Reference.MOD_ID)

    public TutorialMod instance;

 

@SidedProxy(clientSide = Reference.CLIENT_PROXY_CLASS, serverSide = Reference.SERVER_PROXY_CLASS)

public static CommonProxy proxy;

 

@EventHandler

public void preInit(FMLPreInitializationEvent event) {

TutorialItems.init();

TutorialItems.register();

}

 

@EventHandler

public void init(FMLInitializationEvent event) {

proxy.registerRenders();

}

 

@EventHandler

public void postInit(FMLPostInitializationEvent event) {

 

}

}

 

 

When launching Forge Minecraft, I get the following crash report:

 

Description: There was a severe problem during mod loading that has caused the game to fail

You've most likely packaged your mod incorrectly.

Use gradlew build

That is all. Your mod will be in the build/libs folder.
