Question

我刚刚制作了一个插件，用 /info 显示我的服务器的信息。当我尝试启动 Minecraft 服务器时，它会给我一个错误 Invalid plugin.yml ... 我是新手，我不知道如何解决这个问题。它说第 8 行的 plugin.yml 有一个错误，上面写着“信息：”，没有任何空格。

我不知道是什么问题... 这是 Main.java:

package com.carter.minererplugin;

import org.bukkit.plugin.java.JavaPlugin;

import com.carter.minererplugin.commands.infocommand;

public class Main extends JavaPlugin {
    @Override
    public void onEnable() {
        new infocommand(this);
    }
}

这是 infocommand.java

package com.carter.minererplugin.commands;

import org.bukkit.command.CommandExecutor;
import org.bukkit.entity.Player;
import org.bukkit.command.Command;
import org.bukkit.command.CommandSender;
import com.carter.minererplugin.Main;

public class infocommand implements CommandExecutor {
    
    public infocommand(Main plugin) {
        plugin.getCommand("info").setExecutor(this);
    }
    
    public boolean onCommand(CommandSender sender, Command cmd, String label, String[] args) {
        if(!(sender instanceof Player)) {
            sender.sendMessage("You can't run this command from console.");
            return true;
        }
        
        Player p = (Player) sender;
        
        if (p.hasPermission("minerer.use")) {
            p.sendMessage("&lWelcome to MinererSMP!");
            p.sendMessage("--------------------------");
            p.sendMessage("This plugin is currently under heavy development.");
        }
        return false;
    }
}

您在 \t(TAB) 中同时使用 plugin.yml 和空格作为缩进，这可能是复制和粘贴的结果。确保您实际上在整个文件中都使用了空格。

如果您需要，这里有一个在线 YAML Lint：http://www.yamllint.com/ 来检查您的 plugin.yml..
