Java 新客户端上的Kryonet（）给出异常；无法创建序列化程序…”；

我正试图获得一个简单的客户机/服务器类来进行通信，以便以后用于在我的游戏中实现MP。问题是，当我执行

newclient（）

时，我发现

无法创建序列化程序
异常，这显然是由于Kryonet jar中的ASM库过时而导致的问题

好吧，我去做的正是：更新库。我仍然得到错误。最后，我继续尝试在会议上提出的解决方案

但它仍然不起作用

我对这些想法感到茫然，没有更多的在线解决方案与我尝试过的不同，并且严重地浪费了我的时间。我真的需要克服这一点，把它扩大到我的比赛。错误如下：

现在是服务器类：

public class Start {

    private static Server server;
    private int port = 54556;

    public Start() throws IOException{

        server = new Server();
        registerPackets();
        server.addListener(new NetworkListener());
        server.bind(port);
        server.start();

        System.out.println("Port: " + port);
        System.out.println("Starting server...");
    }

    private void registerPackets(){

        Kryo kryo = server.getKryo();
        kryo.register(Packet0LoginRequest.class);
        kryo.register(Packet1LoginAnswer.class);
        kryo.register(Packet2Message.class);
    }

    public static void main(String[] args){
        try {
            new Start();
            Log.set(Log.LEVEL_DEBUG);
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}

嘿，你能弄明白吗？
public class Start {

    private static Server server;
    private int port = 54556;

    public Start() throws IOException{

        server = new Server();
        registerPackets();
        server.addListener(new NetworkListener());
        server.bind(port);
        server.start();

        System.out.println("Port: " + port);
        System.out.println("Starting server...");
    }

    private void registerPackets(){

        Kryo kryo = server.getKryo();
        kryo.register(Packet0LoginRequest.class);
        kryo.register(Packet1LoginAnswer.class);
        kryo.register(Packet2Message.class);
    }

    public static void main(String[] args){
        try {
            new Start();
            Log.set(Log.LEVEL_DEBUG);
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}
