This tutorial assumes you have already

• Read the Pre-requisites
• Downloaded the latest Forge MDK
• Setup your mod folder as described at the top of the main Forge 1.13.2 tutorials page
• Read and followed 1.0 - Gradle Configuration
• Read and followed 1.1 - Importing the project into your IDE
• Read and followed 1.2 - Basic Mod

This tutorial isn’t finished yet. However you can always look at the code in my ExampleMod, where I write and perfect the stuff I teach in these tutorials. My main mod class is here

1) make a >public >no args >constructor with nothing in it
2) Now make a constant logger for your mod
public static final Logger LOGGER = LogManager.getLogger(MODID); (import the log4j logger not the java.util one)
3) Then in your constructor call LOGGER.debug("Hello from YourModName!");
4) for eclipse people refresh /src/
5) If you run your game again, you should be able to see “Hello from YourModName!” in your log
The final result should look something like this

package io.github.cadiboo.examplemod;

import net.minecraftforge.fml.common.Mod;
import org.apache.logging.log4j.LogManager;
import org.apache.logging.log4j.Logger;

/**

@Mod(ExampleMod.MODID)
public final class ExampleMod {

	public static final String MODID = "examplemod";

	public static final Logger LOGGER = LogManager.getLogger(MODID);

	public ExampleMod() {
		LOGGER.debug("Hello from Example Mod!");
	}

}
