Question

我的插件出现问题。错误是“找不到主类'turtdle.abilities.Main'”（我知道我拼写的乌龟错误，但这是我的用户名。）

此插件用于我的服务器。我已经尝试完成plugin.yml文件（包括作者，版本等），还尝试将插件名称更改为“ Main”。我还尝试过将yml移走，但没有成功。

package turtdle.abilities;

import org.bukkit.command.Command;
import org.bukkit.command.CommandSender;
import org.bukkit.entity.Player;
import org.bukkit.permissions.Permission;
import org.bukkit.plugin.PluginManager;
import org.bukkit.plugin.java.JavaPlugin;

public class Main extends JavaPlugin{

    public Permission playerPermission1 = new Permission("turtdle.abilities.get");
    public Permission playerPermission2 = new Permission("turtdle.place.bedrock");
    @Override
    public void onEnable() {
        getLogger().info("onEnable Has been enabled for abilities plugin! BOOP!");
        new PlayerListener(this);
        new BlockRestricter(this);
        PluginManager pm = getServer().getPluginManager();
        pm.addPermission(playerPermission1);
        pm.addPermission(playerPermission2);
    }

    @Override
    public void onDisable() {
        getLogger().info("onDisable Has been triggered for abilities plugin");
    }

    public boolean onCommand(CommandSender sender, Command cmd, String label,
            String[] args) {
        if (cmd.getName().equalsIgnoreCase("hello") && sender instanceof Player) {
            Player player = (Player) sender;
            player.sendMessage("Hewwooo, " + player.getName());
            return true;
        }
        return false;

    }
}

package turtdle.abilities;

import org.bukkit.ChatColor;

import org.bukkit.entity.Player;
import org.bukkit.event.EventHandler;
import org.bukkit.event.Listener;
import org.bukkit.event.entity.PlayerDeathEvent;

public class PlayerListener implements Listener{
    public PlayerListener(Main plugin) {
        plugin.getServer().getPluginManager().registerEvents(this, plugin);
    }
    @EventHandler
    public void onDeath (PlayerDeathEvent e) {
        Player player = e.getEntity();
        if (!player.hasPermission("turtdle.abilities.get")) {
            player.sendMessage(ChatColor.AQUA + "OOF");
        }
        else {
            {
                player.sendMessage(ChatColor.AQUA + "you should've abused...");
            }
        }
    }
}

package turtdle.abilities;

import org.bukkit.ChatColor;
import org.bukkit.block.Block;
import org.bukkit.entity.Player;
import org.bukkit.event.EventHandler;
import org.bukkit.event.Listener;
import org.bukkit.event.block.BlockPlaceEvent;

public class BlockRestricter implements Listener{
    public BlockRestricter(Main plugin) {
        plugin.getServer().getPluginManager().registerEvents(this, plugin);
    }
    @EventHandler
    public void onBlockPlace (BlockPlaceEvent e) {
        Player player = e.getPlayer();
        Block block = e.getBlock();
        if (!player.hasPermission("turtdle.place.bedrock") &&  block.getType().getId() == 7) {
            player.sendMessage(ChatColor.RED + "You CAN'T PLACE THIS " + ChatColor.BOLD + "BLOCK! " + ChatColor.RESET  + ChatColor.RED +  " it is ILLEGAL");
            e.setCancelled(true);

        }
    }
}

嘿，这是我的全部错误

不幸的是，另一个答案不正确。

在您链接的Pastebin中，我们可以看到以下错误：

Caused by: java.lang.ClassNotFoundException: turtdle.Main

当Bukkit尝试加载主类时，它正在寻找类turtdle.Main。奇怪的原因是您的plugin.yml告诉它寻找turtdle.abilities.Main，但它没有这样做。

我对问题原因的猜测是，有时在编译项目时，您的IDE可能实际上没有抓住已编辑的plugin.yml文件放入最终的jar中。要解决此问题，请完成以下步骤：

打开您的项目文件夹，并删除以下任何文件/文件夹（如果存在）：
- bin /
- 目标/
- YourPluginName.jar
转到服务器的文件夹，并在那里删除YourPluginName.jar
重新编译项目，然后将新的jar文件添加到您的plugins文件夹中。

希望这可以解决问题。您的plugin.yml文件和代码看起来都不错，并且理论上应该可以工作。我唯一想到的就是会导致问题的原因。

祝你好运！
