[[1.12] GameRegistry.register() not working]

Hey! I'm new to modding and I'm following Loremaster's starter tutorial on YouTube.
He's modding MC 1.11.2, but I figured that not that much had changed from 1.11.2 to 1.12
Sadly I can't get my GameRegistry.register() to work (It's the only error in the coding) Did something change in there from 1.11.2 to 1.12?

Here is my coding:

 

package init;

import com.shoarmakarma.theuselessmod.Reference;

import items.ItemCraftingbench;
import net.minecraft.client.Minecraft;
import net.minecraft.client.renderer.block.model.ModelResourceLocation;
import net.minecraft.item.Item;
import net.minecraftforge.fml.common.registry.GameRegistry;

public class ModItems {
	
	public static Item craftingbench;

	public static void init(){
		craftingbench = new ItemCraftingbench();
	}
	
	public static void register(){
		GameRegistry.register(craftingbench); //GameRegistry library works, register error says: The method register(K) from the type GameRegistry is not visible
	}
	
	public static void registerRenders(){
		registerRender(craftingbench);
	}
	
	private static void registerRender(Item item){
		Minecraft.getMinecraft().getRenderItem().getItemModelMesher().register(item, 0, new ModelResourceLocation(Reference.MOD_ID + ":" + item.getUnlocalizedName().substring(5), "inventory"));
	}
}
