Text the console when a mob spawns.

Can anybody help me? Thanks in advance. I'm trying to get it to text the console when a mob spawns, but it doesn't work.

Here the code:

Code:

package com.devxyz.ryuautoclick;

import java.util.ArrayList;
import java.util.logging.Logger;

import org.bukkit.Bukkit;
import org.bukkit.command.Command;
import org.bukkit.command.CommandSender;
//import org.bukkit.entity.Entity;
import org.bukkit.entity.LivingEntity;
//import org.bukkit.entity.Monster;
import org.bukkit.entity.Player;
import org.bukkit.entity.Zombie;
import org.bukkit.event.Listener;
import org.bukkit.event.entity.CreatureSpawnEvent;
import org.bukkit.event.entity.CreatureSpawnEvent.SpawnReason;
import org.bukkit.event.entity.EntitySpawnEvent;
import org.bukkit.plugin.java.JavaPlugin;
import org.w3c.dom.events.Event;

import net.md_5.bungee.api.ChatColor;

public class Main extends JavaPlugin implements Listener {
 
    private void msgCS(ChatColor color,String msg) {
        Bukkit.getConsoleSender().sendMessage(color+msg);
    }
 
    public void onEnable() {
        msgCS(ChatColor.GREEN, "--------------------");
        msgCS(ChatColor.YELLOW, "RyuAutoclick Ativado");
        msgCS(ChatColor.GREEN, "--------------------");
     
        this.enabledPlayers = new ArrayList<String>();
     
    }
 
    public void onDisable() {
        msgCS(ChatColor.RED, "--------------------");
        msgCS(ChatColor.YELLOW, "RyuAutoclick Desativado");
        msgCS(ChatColor.RED, "--------------------");
    }
 
    protected ArrayList<String> enabledPlayers;
 
    public final Logger logger = Logger.getLogger("Minecraft");
 
    public void onSpawn(EntitySpawnEvent e) {
        msgCS(ChatColor.RED, "Spawn");
    }
}

 

I think its because you forgot to add @EventHandler ontop of the onSpawn event, And you haven't registered your listener
