Bukkit插件未加载(只有一个命令)

Question

我是Java和Bukkit API的新手，服务器无法加载我的插件，控制台中的错误：https：//pastebin.com/gzglhhhp6。Eclipse警告说，也许不使用"私人插件"旋转中的问题。我的代码：

plugin.java

package Iaiao.main;
import org.bukkit.plugin.java.JavaPlugin;
public class Plugin extends JavaPlugin {
    public void onEnable () {
        getCommand("ip").setExecutor(new Commands(this));
        getLogger().info("Enabled!");
    }
}

commands.java

package Iaiao.main;
import org.bukkit.Bukkit;
import org.bukkit.command.Command;
import org.bukkit.command.CommandExecutor;
import org.bukkit.command.CommandSender;
import org.bukkit.entity.Player;
public class Commands implements CommandExecutor {
    private Plugin plugin;
    public Commands(Plugin plugin) {
        this.plugin = plugin;
    }
    @Override
    public boolean onCommand(CommandSender sender, Command cmd, String label, String[] args) {
        if(args.length == 0) {
            return false;
        }
        String name = args[0];
        Player p = Bukkit.getPlayer(name);
        if(p == null) {
            sender.sendMessage("This player is offline or not registered");
            return true;
        }
        sender.sendMessage("Ip: " + p.getAddress().getAddress());
        return true;
    }
}

plugin.yml

name: Plugin
main: Iaiao.main.Plugin
version: 1.0
commands:
    ip:
        description: Player's IP
        usage: /ip <player>

Answer 1

您的plugin.yml无效：

org.bukkit.plugin.InvalidDescriptionException: Invalid plugin.yml
Caused by: org.yaml.snakeyaml.scanner.ScannerException: while scanning for the next token
found character 't(TAB)' that cannot start any token. (Do not use t(TAB) for indentation)

您的插件中的某个地方是一个选项卡字符，不得使用。
