minecraft spigot插件未发送消息

Question

我对使用JAVA编码非常陌生。欢迎任何提示！这是我的问题： 我正在重新创建一个名为“捉迷藏”的游戏。该插件的基本功能是：将信标放下-保存坐标和放置器名称。在信标中断时，喊出打破信标的人，那是谁的信标。起作用的部分是它应该喊出信标是谁的东西。它没有发布任何内容。这是我的代码：

Main.java

package org.mcuniversitydev.openhoh;

import org.bukkit.plugin.java.JavaPlugin;
import org.mcuniversitydev.openhoh.listeners.beaconlistener.BeaconListener;

public class Main extends JavaPlugin {
   @Override
   public void onEnable() {
       saveDefaultConfig();

       new BeaconListener(this);
   }
}

BeaconListener.java

package org.mcuniversitydev.openhoh.listeners.beaconlistener;


import org.bukkit.Bukkit;
import org.bukkit.Material;
import org.bukkit.entity.Player;
import org.bukkit.event.EventHandler;
import org.bukkit.event.Listener;
import org.bukkit.event.block.BlockBreakEvent;
import org.bukkit.event.block.BlockPlaceEvent;
import org.mcuniversitydev.openhoh.Main;

   String[][][] beacons = {};



   private Main plugin;

   public BeaconListener(Main plugin) {
       this.plugin = plugin;

       Bukkit.getPluginManager().registerEvents(this, plugin);
   }
   @EventHandler
   public void onBlockPlace(BlockPlaceEvent e) {
       Player p = e.getPlayer();
       int bcc[] = {e.getBlock().getX(), e.getBlock().getY(), e.getBlock().getZ()};
       int x = bcc[0];
       int y = bcc[1];
       int z = bcc[2];

       if (e.getBlock().getType() == Material.BEACON) {
