本地测试服务器初始化Minecraft Bukkit插件两次导致启动报错的问题求助

各位大佬好，我正在开发一个Minecraft Bukkit插件，每次启动测试服务器时都会遇到插件重复初始化的错误，具体报错信息如下：

这个错误提示Plugin already initialized!，说明我的插件被初始化了两次，但我已经做了以下排查：

• 试过分别使用Maven打包生成的两个jar包（original-jizzpowerpluginbyandysepp-0.1.1-indev.jar和jizzpowerpluginbyandysepp-0.1.1-indev.jar）单独测试
• 确认插件文件夹里没有放置重复的插件文件

我根据错误堆栈做了分析：
从报错信息里可以看到，第一次初始化是在主类的构造阶段，而第二次初始化是在初始化SilenceWarden监听器的时候触发的，错误根源指向主类JizzpowerpluginByAndysepp的第12行。

我的主类代码如下：

package ch.ksrminecraft.jizzpowerpluginByAndysepp;

import org.bukkit.plugin.java.JavaPlugin;
import ch.ksrminecraft.jizzpowerpluginByAndysepp.commands.GUICommand;
import ch.ksrminecraft.jizzpowerpluginByAndysepp.commands.PlayerTroll;
import ch.ksrminecraft.jizzpowerpluginByAndysepp.listeners.SilenceWarden;
import ch.ksrminecraft.jizzpowerpluginByAndysepp.listeners.InventoryListener;
import ch.ksrminecraft.jizzpowerpluginByAndysepp.utils.TrollTabCompleter;
import ch.ksrminecraft.jizzpowerpluginByAndysepp.utils.ItemBuilder;


public final class JizzpowerpluginByAndysepp extends JavaPlugin { // <-- line 12
    @Override
    public void onEnable() {
        // Plugin startup logic
        registerCommands();
        registerListeners();

    }

    @Override
    public void onDisable() {
        // Plugin shutdown logic
    }

    private void registerCommands() { // registerCommands() is called in onEnable() to register the commands
        getCommand("troll").setExecutor(new PlayerTroll(this));
        getCommand("troll").setTabCompleter(new TrollTabCompleter(this));
        getCommand("trollgui").setExecutor(new GUICommand(this));
    }

    private void registerListeners( ) { // registerListeners() is called in onEnable() to register the listeners
        getServer().getPluginManager().registerEvents(new SilenceWarden(this), this);
        getServer().getPluginManager().registerEvents(new InventoryListener(this), this);
    }
}

我感觉问题应该出在主类里，但实在看不出哪里有问题，为什么会触发插件的两次初始化呢？恳请各位大佬帮忙指点一下！
