当我吃东西时，我的 Spigot Minecraft 插件没有说“yum”

Question

I'm working on a Spigot plugin right now. but I'm having some problems with it. I'm having issues with the listeners. I've watched tutorials but it didn't work. When I eat something in-game it doesn't say "Yum!" It doesn't do anything. I tried to fix it but I can't. I don't think it's because I put it in the same package.

Listeners.java :

package adawda.awdwa;

import org.bukkit.Bukkit;
import org.bukkit.event.EventHandler;
import org.bukkit.event.Listener;
import org.bukkit.event.player.PlayerItemConsumeEvent;
import org.bukkit.event.player.PlayerMoveEvent;
import org.bukkit.plugin.java.JavaPlugin;

public class Listeners extends JavaPlugin implements Listener
{
    public Listeners(Awdwa plugin)
    {

    }
    public void onEnable()
    {
        Bukkit.getPluginManager().registerEvents(this, this);
    }

    @EventHandler
    public void onPlayerItemConsume(PlayerItemConsumeEvent event)
    {
        event.getPlayer().sendMessage("Yum!");
    }
}

Please remove the extends JavaPlugin in your Listeners.class . This will only be needed inside the Main.class . Your Listeners.class should only implement Listener by default. You should then also remove the constructor and the onEnable() method inside your Listeners class as they are not needed.

You should then change your way of registering events inside your Main.class . You should register events like this:

pm.registerEvents(new Listeners(), this);

(Create a new Listeners Object inside the registerEvents() method)
