在Minecraft bukkit插件中找不到主类

Question

我正在尝试学习如何编写minecraft插件，但是我在开始时遇到了一点问题，当我尝试运行导出的插件时，我得到一个主类未找到错误。我已经尝试移动plugin.yml文件，检查所有部分都导出和重命名类等无济于事。也阅读了现有的问题。任何帮助都将不胜感激。

主要：

package me.raultechsupport.helloworld;

import org.bukkit.plugin.java.JavaPlugin;
import me.raultechsupport.helloworld.commands.hellocommand;

public class Main extends JavaPlugin {

    @Override
    public void onEnable() {
        new hellocommand(this);
    }
}

helloCommand：

package me.raultechsupport.helloworld.commands;

import org.bukkit.command.Command;
import org.bukkit.command.CommandExecutor;
import org.bukkit.command.CommandSender;
import org.bukkit.entity.Player;
import me.raultechsupport.helloworld.Main;

public class hellocommand implements CommandExecutor {

    @SuppressWarnings("unused")
    private Main plugin;

    public hellocommand(Main plugin) {
        this.plugin = plugin;
        plugin.getCommand("hello").setExecutor(this);
    }

    @Override
    public boolean onCommand(CommandSender sender, Command cmd, String label, String[] arg3) {
        if (!(sender instanceof Player)) {
            sender.sendMessage("Only players may execute this command!");
            return true;
        }
        Player p = (Player) sender;

        if (p.hasPermission("hello.use")) {
            p.sendMessage("Hi!");
            return true;
        } else {
            p.sendMessage("You do not have permission to execute this command!");
        }

        return false;
    }

}

插件。yml：

name: HelloWorld
version: 1.0
author: RaulTechSupport
main: me.raultechsupport.helloworld.Main
description: Hello.

commands:
  hello:
    aliases: [hi]
    description: Hi!

控制台错误：

你应该把你的插件。如果您使用Eclipse进行编译，则在源文件夹（src）中使用yml。如果使用IntelliJ，请将文件放在“资源”文件夹中。您的API（Spigot或Bukkit）无法加载文件，因为它实际上没有在最终的<代码>中导出。jar文件。您可以通过使用7Zip或WinRAR等存档程序打开Jar文件来查看文件是否已导出。插件。yml应该位于文件的根目录下。

我已经有一段时间没有编写插件了，但回顾一下我以前做的，我的插件。yml不位于参考库中：

还有，我的插件。yml与您的有点不同：
