[1.7.10] Make command with arguments, export a addon and make it run in server

[PlayerNerd]

I´m trying to create a addon mod, that it runs in server withou a client, but i need help to make a command with arguments and export it.

My addon only add commands to minecraft.

 

Main.class

 

package com.playernerd.PlayerNerd.Nerdmon.Main;

import net.minecraft.command.ICommandManager;
import net.minecraft.command.ServerCommandManager;
import net.minecraft.init.Blocks;
import net.minecraft.server.MinecraftServer;
import cpw.mods.fml.common.Mod;
import cpw.mods.fml.common.Mod.EventHandler;
import cpw.mods.fml.common.event.FMLInitializationEvent;
import cpw.mods.fml.common.event.FMLServerStartingEvent;

@Mod(modid = Main.MODID, version = Main.VERSION)
public class Main
{
    public static final String MODID = "PlayerNerdMon";
    public static final String VERSION = "1.0";
    
    @EventHandler
    public void init(FMLInitializationEvent event)
    {
    	
    }
    
    @EventHandler
    public void onServerStart(FMLServerStartingEvent event)
    {
    	
    	MinecraftServer server = MinecraftServer.getServer(); // single player only? // This is line 62 as shown below in the error.
    	ICommandManager command = server.getCommandManager();
    	ServerCommandManager manager = (ServerCommandManager) command;
    	
        manager.registerCommand(new CommandSpawn());
    }

}

 

I only try to make one command, the code:

 

package com.playernerd.PlayerNerd.Nerdmon.Main;

import net.minecraft.command.CommandBase;
import net.minecraft.command.ICommandSender;
import net.minecraft.entity.player.EntityPlayer;
import net.minecraft.server.MinecraftServer;
import net.minecraft.world.WorldServer;

import com.pixelmonmod.pixelmon.config.PixelmonEntityList;
import com.pixelmonmod.pixelmon.entities.pixelmon.EntityPixelmon;
import com.pixelmonmod.pixelmon.enums.EnumGrowth;
import com.pixelmonmod.pixelmon.enums.EnumNature;
import com.pixelmonmod.pixelmon.enums.EnumPokemon;

public class CommandSpawn extends CommandBase
{

@Override
public String getCommandName()
{
	return "pnspawn";
}

@Override
public String getCommandUsage(ICommandSender icommandsender) 
{
	return "/pnspawn <nome> <level> <s/ns> <tamanho> <nature>";
}

@Override
public void processCommand(ICommandSender icommandsender, String[] args) 
{
	if(icommandsender instanceof EntityPlayer)
	{
		EntityPlayer p = (EntityPlayer) icommandsender;
		EntityPixelmon pkm;
		String name;
		WorldServer world;
		name = args[0];

		if(EnumPokemon.hasPokemon(name))
		{
			pkm = (EntityPixelmon) PixelmonEntityList.createEntityByName(name, p.worldObj);
			String lvl = args[1];
			pkm.getLvl().setLevel(Integer.valueOf(lvl));
			String shiny = args[2];
			switch(shiny)
			{
			case "s":
				pkm.setIsShiny(true);
				break;
			case "ns":
				pkm.setIsShiny(false);
				break;
			}

			String growth = args[3];

			switch(growth)
			{
			case "ginormous":
				pkm.setGrowth(EnumGrowth.Ginormous);
				break;
			case "enormous":
				pkm.setGrowth(EnumGrowth.Enormous);
				break;
			case "giant":
				pkm.setGrowth(EnumGrowth.Giant);
				break;
			case "huge":
				pkm.setGrowth(EnumGrowth.Huge);
				break;
			case "ordinary":
				pkm.setGrowth(EnumGrowth.Ordinary);
				break;
			case "runt":
				pkm.setGrowth(EnumGrowth.Runt);
				break;
			case "small":
				pkm.setGrowth(EnumGrowth.Small);
				break;
			case "pygmy":
			    pkm.setGrowth(EnumGrowth.Pygmy);
			    break;
			case "microscopic":
				pkm.setGrowth(EnumGrowth.Microscopic);
				break;
			}

			p.worldObj.spawnEntityInWorld(pkm);

		} else {

		}

	}

}

}
