我的Bukkit插件命令在运行时总是抛出异常。
当我输入我的命令时：/config set（它应该将信息保存到文件/配置），我在聊天中收到此错误：
尝试执行此命令时发生内部错误。
为什么会这样？

数组总是从索引0开始。因此，要访问玩家是否指定“获取”或“设置”，您应该替换
args[1].equalsIgnoreCase("set")
args[1].equalsIgnoreCase("get")
与
args[0].equalsIgnoreCase("set")
args[0].equalsIgnoreCase("get")
另外，不确定你用线路做什么
sender.sendMessage("§6Registering player§c " + args[0] + "§6 to Server....");
args [0]指的是“get”或“set”。据推测，你应该用“nick”替换它并在
之后插入行String nick = p.getName().toLowerCase();
