我是Bukkit API的新手，不久前我学习了java。我正在制作一个小游戏插件。
虽然Eclipse没有给我任何错误，但它似乎来自我的主类。 Minecraft确实启动了，但是控制台记录了插件无法启动的情况，当我执行命令时它会被重复。
这是我的主要课程

这是我得到的错误

启用MiniGame v1.0时出错（是否为最新版本？） java.lang.IllegalArgumentException：插件已初始化！
你的插件因为已经加载而无法加载，我认为创建重复的注册监听器或插件的任何其他部分存在问题。

所以我检查了你说的链接，问题非常接近链接中的问题。为了解决这个问题，我刚从侦听器类中删除了MainClass导入，然后以不同的方式导入了MainClass。
