My code is simple and only uses the enables:

Code:

package com.cavariux.bukkit;

import org.bukkit.ChatColor;
import org.bukkit.Material;
import org.bukkit.entity.Player;
import org.bukkit.event.EventHandler;
import org.bukkit.event.EventPriority;
import org.bukkit.event.entity.PlayerDeathEvent;
import org.bukkit.inventory.ItemStack;
import org.bukkit.plugin.java.JavaPlugin;

public class Killerdrops extends JavaPlugin {
   
    @Override
    public void onEnable(){
        getLogger().info("KillDrops v1.0 has been Enabled");
    }
   
    @Override
    public void onDisable(){
        getLogger().info("KillDrops v1.0 has been Enabled");
    }
   
}

My Plugin.YML is like this:

name: Killerdrops
main: com.cavariux.bukkit.Killerdrops
version: 1.0
description: Cada vez que matas a alguien te daran dos gemas
