需要有关minecraft插口插件的帮助。
这是布局（或者构建路径，如果您想这样称呼它的话）
下面是主文件（main.java）的代码

package com.angosa;

import org.bukkit.plugin.java.JavaPlugin;

import com.angosa.listener.Listeners;

public class Main extends JavaPlugin {
    @Override

    public void onEnable() {
        getServer().getPluginManager().registerEvents(new Listeners(), this);

    }
}

下面是listeners.java（在listener包中）的代码

package com.angosa.listener;
import org.bukkit.entity.Creeper;

import org.bukkit.entity.EntityType;
import org.bukkit.event.EventHandler;
import org.bukkit.event.Listener;
import org.bukkit.event.entity.CreatureSpawnEvent;

public class Listeners implements Listener {
    @EventHandler
    public void creatureSpawn(CreatureSpawnEvent event) {
        if(event.getEntityType() == EntityType.CREEPER) {

            Creeper creeper = (Creeper) event.getEntity();

            creeper.setPowered(true);
            creeper.setHealth(100);
            creeper.setExplosionRadius(200);

        }
    }
}

这是yml文件

main: com.angosa.Main
name: OPCreeper
version: 1.0
author: Claim

另外，如果版本不对，下面是我上传到服务器时的样子。
