感谢您的任何帮助 插件不能为空错误 – Spigot 编程

编辑:如果我在启动服务器后重新加载插件,它在某种程度上可以正常运行。

不要使用 Main.getPlugin(Main.class),尝试使用 JavaPlugin.getPlugin(Main.class)。另外,你为什么要创建 Main 类的实例?在Bukkit插件中不需要单例模式(实际上它并不是真正的单例,因为你无法将构造函数的访问级别设置为私有)。另外,尝试将插件的主类命名为插件的名称,例如:如果你的插件名是AchievementsX,那么将你的主类命名为AchievementsX,通过这种命名方式,你可以轻松地将你的插件集成到其他插件中。

英文:

instead of using Main.getPlugin(Main.class) try using JavaPlugin.getPlugin(Main.class). Also, why do you create an Instance of your Main class? You dont need singletons in Bukkit plugins (in fact it isnt a real singleton, because you cant set the access of your constructor to private). Also, try naming your Main class of a plugin as the name of your plugin, example: Your plugins name is AchievementsX, then name your main class AchievementsX, with this naming you can easily implement your plugin into other plugins.
