错误：INFO引起：java.lang.ClassCastException：com.ShlobdonG.gMarry.Commands无法强制转换为org.bukkit.plugin.Plugin

代码：

if (cmd.getName().equalsIgnoreCase("vmarry")) {
    if (!(player == null)) {
        if (!player.hasPermission("gmarry.marry")) {
            sender.sendMessage("You can't marry a player because of permission!");
            return true;
        } else {

            int cooldown = this.plugin.getConfig().getInt(
                    "request-cooldown");
            if (this.plugin.vmarry.containsKey(player.getName())) {
                long diff = (System.currentTimeMillis() - this.plugin.vmarry
                        .get(sender.getName())) / 1000;
                if (diff < cooldown) {
                    player.sendMessage("You must wait "
                            + cooldown
                            + " seconds before marrying another player.");
                    return false;
                }
            }
        }
        if (args.length > 0) {
            final Player target = Bukkit.getServer().getPlayer(
                    args[0]);
            long keepAlive = this.plugin.getConfig().getLong(
                    "keep-alive") * 20;

            if (target == null) {
                sender.sendMessage("You can only marry players that are online!");
                return false;
            }
            if (target == player) {
                sender.sendMessage("You can't bite yourself!");
                return false;
            }

            sendRequest(player, target);

            Bukkit.getServer()
                    .getScheduler()
                    .scheduleSyncDelayedTask((Plugin) this,
                            new Runnable() {
                                public void run() {
                                    killRequest(target.getName());
                                }
                            }, keepAlive);

            this.plugin.vmarry.put(player.getName(),
                    System.currentTimeMillis());
        } else {
            player.sendMessage("Attempt to marry player..");
            player.sendMessage("/vmarry <player>");
        }
    }
}

我意识到代码很乱，但导致ClassCatException的问题在哪里？我迷路了...

Answer 1

at com.ShlobdonG.gMarry.Commands.onCommand（Commands.java:182）

scheduleSyncDelayedTask((Plugin) this

引起：java.lang.ClassCastException：com.ShlobdonG.gMarry.Commands无法强制转换为org.bukkit.plugin.Plugin

有道理，对吗？

public class Commands可能无法扩展/实施Plugin

命令运行时的java.lang.ClassCastException。一切正常，内部错误发生消息
