Question

我只是在测试一些基本的Bukkit插件，试图让它们工作以便我可以测试它们。我的插件（我实际上是从Bukkit wiki复制的）

一直出现同样的错误

以下是错误消息：

现在，我要做的就是让这个插件加载到我的服务器上。这里的主要错误是Invalid plugin.yml。这是我的plugin.yml文件：

name: Test
main: com.hasherr.bukkit.test.Main
version: 1.0
commands:
  ignite:
        description: Sets the designated player on fire.
        usage: /ignite [player]
        permissions: Test.ignite
        permission-message: You can't use that command.

关于插件的实际代码，这里是：

public final class Main extends JavaPlugin
{

    @Override
    public void onEnable()
    {
        getLogger().info("Test plugin has been enabled.");
    }

    @Override
    public void onDisable()
    {
        getLogger().info("Test plugin has been disabled.");
    }

    @Override
    public boolean onCommand(CommandSender sender, Command cmd, String label, String[] args) {
        // Uses equalsIgnoreCase() over equals() to accept "ignite" and "IgNiTe."
        if (cmd.getName().equalsIgnoreCase("ignite")) {
            // Make sure that the player specified exactly one argument (the name of the player to ignite).
            if (args.length != 1) {
                // When onCommand() returns false, the help message associated with that command is displayed.
                return false;
            }

            // Make sure the sender is a player.
            if (!(sender instanceof Player)) {
                sender.sendMessage("Only players can set other players on fire.");
                sender.sendMessage("This is an arbitrary requirement for demonstration purposes only.");
                return true;
            }

            // Get the player who should be set on fire. Remember that indecies start with 0, not 1.
            Player target = Bukkit.getServer().getPlayer(args[0]);

            // Make sure the player is online.
            if (target == null) {
                sender.sendMessage(args[0] + " is not currently online.");
                return true;
            }

            // Sets the player on fire for 1,000 ticks (there are ~20 ticks in second, so 50 seconds total).
            target.setFireTicks(1000);
            return true;
        }
        return false;
    }

}

有人可以告诉我为什么我收到的Invalid plugin.yml消息不允许我的插件运行吗？如果您需要更多详细信息/信息，请告诉我，我很乐意进行编辑。

Answer 1

你的plugin.yml中有标签，这是不允许的。如果您使用一定数量的空格替换所有选项卡（根据我的经验最常见4个），代码将按预期运行。

如果您在Notepad ++中对其进行编辑，请使用Edit -> Blank Operations -> TAB to Space自动将所有标签替换为空格。

Answer 2

您还可以配置每次按TAB键时它会自动转换为空格。另外，您可以定义按TAB时应插入的空格数。我个人使用4个空格，在工作中我们使用标准的2个空格。

您可以在NotePad + here

中找到选项

Settings -> Preferences -> Tab Settings

您可以为每种语言和默认值定义它。只需标记“空格替换”
