自定义插件不会出现在 Minecraft 中？

Question

我正在制作一个小原型插件，每分钟都可以强化小怪，但该插件没有出现在服务器上。

插件导出为 jar 文件并放入服务器的 plugins 文件夹中。

非常感谢所有帮助。谢谢！

我的 3 个脚本在这里：

主脚本：

package csw.lvlupmobs.plugin;

import org.bukkit.Bukkit;
import org.bukkit.scheduler.BukkitScheduler;
import org.bukkit.command.Command;
import org.bukkit.command.CommandSender;
import org.bukkit.plugin.java.JavaPlugin;

public class Main extends JavaPlugin {

    private static Main instance;

    public static Main getInstance() {


        return instance;
    }


    @Override
    public boolean onCommand(CommandSender sender,
                             Command command,
                             String label,
                             String[] args) {
        if (command.getName().equalsIgnoreCase("initiatelevelup")) {
            sender.sendMessage("Mobs will now strengthen every minute!");
            Listeners.doLevels = true;
            levelup();
            return true;
        }
        return false;
    }

    public void levelup() {

        BukkitScheduler scheduler = Bukkit.getServer().getScheduler();

        scheduler.scheduleSyncDelayedTask(this, new Runnable() {
            @Override
            public void run() {
                Listeners.moblvl++;
                Bukkit.broadcastMessage("All mobs have leveled up! New mobs will now spawn at level " 
+ Listeners.moblvl + ".");
            }
        }, 1200);

    }

    @Override
    public void onEnable() {

        instance = this;

        getServer().getPluginManager().registerEvents(new Listeners(), this);

    }
    @Override
    public void onDisable() {

        instance = null;
    }
}

        if(event.getEntityType() == EntityType.SPIDER) {

            Spider spider = (Spider) event.getEntity();

            spider.getAttribute(Attribute.GENERIC_MOVEMENT_SPEED).setBaseValue(0.3 * moblvl * 0.2);
            spider.getAttribute(Attribute.GENERIC_ATTACK_DAMAGE).setBaseValue(0.34 * moblvl * 2);
            spider.addPotionEffect(new PotionEffect(PotionEffectType.JUMP, 99999, (int)(moblvl * 0.34)));
        }
    }
}

plugin.yml:

version: 1.0

commands:
    initiatelevelup:

       usage: /initiatelevelup

Answer 1

你的名字中有一个空格...... 不要在你的 plugin.yml 中使用空格字母。

但我认为你可以在“作者”中使用它

Answer 2

我把它加载到我的服务器上，问题出在你的 plugin.yml 中。首先用法：没有意义该命令的使用从描述中应该是显而易见的。其次，plugin.yml 中的间距错误，并且您在不允许的地方使用了 [tab]，您必须手动正确地对其进行间距。我建议制作一个 plugin.yml 模板，这样您就可以将其复制并粘贴到您的项目中并填写您需要的内容。

固定plugin.yml：

csw.lvlupmobs.plugin.Main
name: mobs that level-up
version: 1.0
author: Austin Powers
description: Every minute, all of the mobs increase in strength
commands:
  initiatelevelup:
    description: Enables mobs to level-up
