[1.12.2] How to write a proxy

[gomalley411]

I'm nearly done making my first ever Forge mod, but for some reason I can only run it out of Eclipse. Whenever I try and run it out of the launcher it says that it's unable to connect to the authentication server. I asked around on Reddit and they told me to make sure I wrote my ClientProxy, ServerProxy and CommonProxy classes. What can I do to fix this?

 

Here's my CommonProxy file:

package com.example.examplemod;

import net.minecraftforge.fml.common.Mod;
import net.minecraftforge.fml.common.eventhandler.*;
import net.minecraftforge.event.*;
import net.minecraft.client.renderer.block.model.ModelResourceLocation;
import net.minecraft.item.*;
import net.minecraftforge.client.model.*;
import net.minecraftforge.client.event.*;

@Mod.EventBusSubscriber
public class CommonProxy {
	
	@SubscribeEvent
	public static void registerRenders(ModelRegistryEvent event) {
		registerRender(ExampleMod.mySword);
	}
	
	private static void registerRender(Item item) {
		ModelLoader.setCustomModelResourceLocation(item, 0, new ModelResourceLocation (item.getRegistryName(), "inventory"));
	}
	
	@SubscribeEvent
	public static void registerItems(RegistryEvent.Register<Item> event) {
		event.getRegistry().registerAll(ExampleMod.mySword);
	}
}

 

And here's my main mod class:

package com.example.examplemod;

import net.minecraft.init.Blocks;
import net.minecraft.item.Item;
import net.minecraft.item.Item.ToolMaterial;
import net.minecraftforge.fml.common.Mod;
import net.minecraftforge.fml.common.Mod.EventHandler;
import net.minecraftforge.fml.common.event.FMLInitializationEvent;
import net.minecraftforge.fml.common.event.FMLPreInitializationEvent;
import org.apache.logging.log4j.Logger;
import net.minecraftforge.common.util.EnumHelper;

@Mod(modid = ExampleMod.MODID, name = ExampleMod.NAME, version = ExampleMod.VERSION)
public class ExampleMod
{
    public static final String MODID = "sword";
    public static final String NAME = "George's Custom Sword Mod";
    public static final String VERSION = "1.0";

    private static Logger logger;
    
    // New variables
    public static ToolMaterial myToolMaterial;
    public static Item mySword;

    @EventHandler
    public void preInit(FMLPreInitializationEvent event)
    {
        logger = event.getModLog();
        
        myToolMaterial = EnumHelper.addToolMaterial("light", 4, 1000000, 2, 10, 10);
        mySword = new CustomSword();
    }

    @EventHandler
    public void init(FMLInitializationEvent event)
    {
        // some example code
        logger.info("DIRT BLOCK >> {}", Blocks.DIRT.getRegistryName());
    }
}

All this mod does is give you one extra sword in the creative inventory -- that's it. Can someone help?
