Android studio 编译报错：Supertypes of the following classes cannot be resolved. Please make sure you have the required dependence

Android studio版本：

具体操作：

       1、新增一个module，将Java-WebSocket 导入moudle（

    implementation "org.java-websocket:Java-WebSocket:1.5.1"

）；

       2、新建类继承WebSocketClient：

public class JWebSocketClient extends WebSocketClient {

    public JWebSocketClient(URI serverUri) {
        super(serverUri, new Draft_6455());
    }

    @Override
    public void onOpen(ServerHandshake handshakedata) {
        Log.e("JWebSocketClient", "onOpen()");
    }

    @Override
    public void onMessage(String message) {
        Log.e("JWebSocketClient", "onMessage()");
    }

    @Override
    public void onClose(int code, String reason, boolean remote) {
        Log.e("JWebSocketClient", "onClose()");
    }

    @Override
    public void onError(Exception ex) {
        Log.e("JWebSocketClient", "onError()");
    }

}

     3、编译。

   编译时报错：Supertypes of the following classes cannot be resolved. Please make sure you have the required dependence

  修改方法：1、file->Invalidate Caches/Restart；

                     2、如果还是报错 Build->Clear Project / Rebuild Project；

                     3、如果还是报错 重启电脑。
