Bukkitプラグインはすでに

Question

を初期化：java.lang.IllegalArgumentException: Plugin already initialized!

プラグインは動作しますが、イベント「AdventureMode」ない、ここのコードは次のとおりです。

package net.battleheroes.spigot.spacepvp; 

import org.bukkit.Bukkit; 
import org.bukkit.plugin.PluginManager; 
import org.bukkit.plugin.java.JavaPlugin; 

import net.battleheroes.spigot.spacepvp.cmd.Feed; 
import net.battleheroes.spigot.spacepvp.cmd.Fly; 
import net.battleheroes.spigot.spacepvp.cmd.Heal; 
import net.battleheroes.spigot.spacepvp.cmd.Kits; 
import net.battleheroes.spigot.spacepvp.cmd.Spacepvp; 
import net.battleheroes.spigot.spacepvp.cmd.gamemode; 
import net.battleheroes.spigot.spacepvp.util.AdventureMode; 
import net.battleheroes.spigot.spacepvp.util.ChatFormatting; 
import net.battleheroes.spigot.spacepvp.util.Messages; 

public class MainClass extends JavaPlugin implements ChatFormatting, Messages{ 


    public void onEnable() { 
     Bukkit.getServer().getLogger().info(tag + green + enabled + orange + brand); 

     registerCommands(); 
     registerEvents(); 

    } 

    public void onDisable() { 
     Bukkit.getServer().getLogger().info(tag + red + disabled + orange + brand); 
    } 

    public void registerCommands() { 

     getCommand("spacepvp").setExecutor(new Spacepvp()); 
     getCommand("kit").setExecutor(new Kits()); 
     getCommand("heal").setExecutor(new Heal()); 
     getCommand("feed").setExecutor(new Feed()); 
     getCommand("fly").setExecutor(new Fly()); 
     getCommand("gamemode").setExecutor(new gamemode()); 

    } 

    public void registerEvents() { 
     PluginManager pm = getServer().getPluginManager(); 

     pm.registerEvents(new AdventureMode(), this); 
    } 


} 

私は同じクラスの他のプラグインはなく、テストサーバーのディレクトリは空です。

問題は、次のスタックトレース抜粋に注釈を付けたように、Flyインスタンスの建設中に発生。

悲しいことに、私は追加のソースコードなしであなたに伝えることができます。 Flyのコンストラクタおよび/またはそのスーパークラスのコンストラクタを調べて、JavaPlugin派生クラスの別のインスタンスを作成しようとしていないことを確認します。私はFlyがMainClassまたはJavaPluginから拡張されていると思われます。
