报错的那行代码就是在插件主类的onEnable()里的
new BukkitRunnable(){ public void run(){ ...... } }.runTaskTimer(this, 0L ,20L);

在onEnable的同时注册的scheduler不可以在设定0延迟（因为classLoader未完成载入）

也就是runTaskTimer(this, 0L ,20L);
改成runTaskTimer(this, 1L ,20L);

PluginMain$1与PluginMain之间有什么关系吗

PluginMain$1为PluginMain中定义的（编译顺序上）第一个匿名类，因为**，所以编辑时java自动命名为$+数字
