java.lang.ClassNotFoundException Mod Class Not found :S

Posted December 4, 20159 yr

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.

I do Forge for free, however the servers to run it arn't free, so anything is appreciated.

(((SOLVED))) Loading into certain worlds stuck on "Reading world data" then stops responding.

So, I tried this, and the world did load, but ALL of the modded items and things I had completely disappeared, as well as many unmodded things like my chests and items I was carrying. Any solutions?

How do I remove 3d headlayer on NPC's skin in CustomNpc? (1.16.5)

I do have to add that this is my answer for 1.12.2 but it should ALSO work for future versions.

How do I remove 3d headlayer on NPC's skin in CustomNpc? (1.16.5)

I know this was posted almost 3 years ago but this is for anyone who is still looking for an answer.

First, find your config folder. -> C:\Users\ (desktop user's name) \curseforge(or the application where you've downloaded you mod)\minecraft\Instances\config (The config folder should be in the same folder as your mods folder.) Once you click on the config folder, search for CustomNpcs.cfg. Once found, click on it (you can edit it using notepad) and search for the line "headweartype". Set the value to 0 if you want a 2d head layer, set it to 1 for a 3d head layer. Then save the options and you should be good to go from there! :)
