您好，我以前创建过基本的Bukkit服务器插件，并且运行正常。我正在创建一个新的，但由于某种原因，它不会运行该命令。只是为了澄清，插件YAML是正确完成的（导入也是如此，我只是觉得不需要包含它们），并且没有编译错误。我在命令YAML文件中有命令，当我加载插件时，它会显示在我的插件列表中，当我执行/帮助时。当我运行命令时，它只返回用法：＆＃39; / party＆＃39;，但不会执行其他操作（向播放器发送帮助消息）。我不太确定为什么它不起作用。我错误地忘记了什么吗？此外，这是我的第一个问题，如果不符合标准，请道歉。

Answer 1

我不确定我上面的人在说什么，但让我解释一下： 是的，使用cmd.getName（）比commandLabel更好，这就是原因： 在plugin.yml中注册命令时，必须为其命名。然后在这个名称下你可以设置它的描述，权限等等，最重要的是在这种情况下 - 它的别名。设置其别名时，将在命令中调用任何别名时运行该命令。标签将是运行的确切别名，cmd.getName（）将是您注册的命令的名称。 至于你的问题，我猜这是在这一行：

public boolean onCommand(CommandSender theSender, Command cmd, String[] args, String commandLabel)

应该是

public boolean onCommand(CommandSender theSender, Command cmd, String commandLabel, String[] args)

订单始终是CommandSender，Command，String，String []。 你应该在你的onCommand方法上面添加@Override标签，这样就会抛出这样的错误，你就会知道这就是问题所在。

问题是在开始时你有terminator如果我没有错，就是要求命令提示符/ cmd获取用户名。

我相信你想要的是对你的命令进行排列。所以对于前者。 if(cmd.getName().equalsIgnoreCase("party"))

在代码中我添加了一些注释来帮助您应用插件。

首先，您要通过执行以下操作来设置第一个命令：

/party help, /party setup ...

现在在关闭命令之前，您现在想要添加如果 if(label.equalsIgnoreCase("PoP") || label.equalsIgnoreCase("PoliticalParty")){ //this will be your first command so you want to replace cmd.getName().equalsIgnoreCase("party") as that is really wrong //below tells the user if command is just "POP" then give user message if(args.length == 0){//if less then 0 input player.sendMessage("Wrong command type /pop help"); } 多于一个的参数。 所以在上面的代码下面把它放在：

args.length
