当我测试我的新插件时,一个异常一直被抛出:java.lang.IllegalArgumentException:插件已经初始化!请帮忙!代码如下:

package me.plugin.example;

import org.bukkit.plugin.java.JavaPlugin;

import org.bukkit.event.Listener;

import org.bukkit.ChatColor;

import org.bukkit.GameMode;

import org.bukkit.command.Command;

import org.bukkit.command.CommandSender;

import org.bukkit.entity.Player;

import org.bukkit.event.EventHandler;

import org.bukkit.event.player.PlayerJoinEvent;

public class Main extends JavaPlugin implements Listener {

@Override

public void onEnable() {

getServer().getPluginManager().registerEvents(new Main(), this);

}

@EventHandler

public void onPlayerJoinEvent(PlayerJoinEvent event) {

Player p = event.getPlayer();

event.setJoinMessage(ChatColor.AQUA + p.getPlayerListName() + " has joined the game.");

p.sendMessage(ChatColor.GOLD + "" + ChatColor.BOLD + "Welcome to the server!");

p.setGameMode(GameMode.ADVENTURE);

}

@Override

public boolean onCommand(CommandSender sender, Command cmd, String label, String[] args) {

Player player = (Player) sender;

if (cmd.getName().equalsIgnoreCase("example")) {

player.sendMessage(ChatColor.BOLD + ""+ ChatColor.ITALIC + "Hello! Hope you like to be set on fire. lol :P");

player.setFireTicks(20);

}

return true;

}

@Override

public void onDisable() {

}

}

我知道你只需要为每个插件声明一个JavaPlugin类,我想我正在这么做。但它一直在说:

java.lang.IllegalArgumentException: Plugin already initialized!
