我的 Minecraft Spigot 插件没有报告回来

Question

我对 Java 编码还是很陌生，我已经完成了一些教程，这些教程很棒，但我不知道为什么它在游戏中不起作用。我已经尝试了所有方法，例如更改它并查看了许多不同的论坛。事件有两个类（加入和离开事件）和主类。我已确保检查是否导入它们并且没有错误让我从我查看的位置查看。如果有人能提供帮助，那将是一种祝福。

代码：- 主类：

package me.JimmyClown.FirstPlugin;

import org.bukkit.plugin.java.JavaPlugin;

public class MainClass extends JavaPlugin {
    
@Override 
   
public void onEnable() {

        System.out.println("It works!");
        getServer().getPluginManager().registerEvents(new PlayerJoin(), this);
        getServer().getPluginManager().registerEvents(new PlayerLeave(), this);
    }
    
    @Override
    public void onDisable() {
        
    }       
}

**Code for the Join-Class:**

package me.JimmyClown.FirstPlugin;

import org.bukkit.ChatColor;
import org.bukkit.entity.Player;
import org.bukkit.event.EventHandler;
import org.bukkit.event.Listener;
import org.bukkit.event.player.PlayerJoinEvent;

public class PlayerJoin implements Listener{
    
@EventHandler
    
void onPlayerJoin(PlayerJoinEvent e) {
        
Player player = e.getPlayer();
        
e.setJoinMessage(ChatColor.BLUE + "Welcome back to the server!" + player.getDisplayName());
    }   
}

**Code for Leave Class:**
package me.JimmyClown.FirstPlugin;

import org.bukkit.ChatColor;
import org.bukkit.entity.Player;
import org.bukkit.event.EventHandler;
import org.bukkit.event.Listener;
import org.bukkit.event.player.PlayerQuitEvent;

public class PlayerLeave implements Listener {
    @EventHandler
    void onPlayerLeave(PlayerQuitEvent e) {
        Player player = e.getPlayer();
        e.setQuitMessage(ChatColor.DARK_BLUE + "Awwww, We hope we see you soon" + player.getDisplayName());
    }   
}

plugin.yml：

version: 1.0

尝试将事件方法的访问修饰符设置为public。

public void onPlayerLeave(PlayerQuitEvent e) { }

public void onPlayerJoin(PlayerJoinEvent e) { }
