Java 为什么我的程序在使用maven打包后跳出循环？

我已经编写了一个程序，使用TCP/IP在我的服务器之间发送当前IP。当我在IDE中运行程序时，一切正常，我得到了预期的结果，但当我使用Maven打包它时，程序只运行一次，并立即跳出循环。有人能帮我理解为什么会这样吗

public String getIP () throws UnknownHostException {
    InetAddress myIP=InetAddress.getLocalHost();

    //System.out.println("My IP Address is:");
    //System.out.println(myIP.getHostAddress());
    String IP = myIP.getHostAddress();

    return IP;
}

public String getID(){

    JFrame f;

    f=new JFrame();
    String ID=JOptionPane.showInputDialog(f,"Enter GSID");

    return ID;
}

public static void main(String args[]) throws IOException, InterruptedException {

    Socket s1 = null;
    BufferedReader br = null;
    BufferedReader is = null;
    PrintWriter pwr = null;

    client obj = new client();
    String CID = obj.getID();
    String response = null;

    while(true) {

        String ServerIP = "173.16.1.5";
            s1 = new Socket(ServerIP, 4445);
            br = new BufferedReader(new InputStreamReader(System.in));
            is = new BufferedReader(new InputStreamReader(s1.getInputStream()));
            pwr = new PrintWriter(s1.getOutputStream());

            // send ID to Server
            pwr.println(CID);
            pwr.flush();
            response = is.readLine();
            System.out.println("Server Response : " + response);

            // get IP and send to Server
            client IP = new client();
            String CIP = IP.getIP();

            pwr.println(CIP);
            pwr.flush();
            response = is.readLine();
            System.out.println("Server Response : " + response);

            // send time
            DateTimeFormatter dtf = DateTimeFormatter.ofPattern("yyyy-MM-dd HH:mm:ss");
            LocalDateTime now = LocalDateTime.now();
            pwr.println(dtf.format(now));
            pwr.flush();
            response = is.readLine();
            System.out.println("Server Response : " + response);

            is.close();
            pwr.close();
            br.close();
            s1.close();
            System.out.println("Connection Closed");

            JFrame f;

            f=new JFrame();
        TimeUnit.SECONDS.sleep(10);
        }

    }
}

那么，只是为了确认——您是否只看到一次输出，然后程序停止？您确定没有异常吗？是的，我只看到一次输出，而不是第二次，不应该有任何异常，因为ide中没有异常。但是如果有，我如何在ide之外的控制台中看到异常呢？（我试过cmd，但没有成功）
