如何在执行“git fetch -v --progress”时输入密码 “来自java中的ProcessBuilder

Question

该程序不允许输入密码，它在读取通过扫描仪输出的命令时基本挂起。基本上我试图从git存储库中获取一个分支。

    ProcessBuilder builder = new ProcessBuilder( "cmd" );
    builder.redirectErrorStream(true);
    Process process = null;
    try {
        process = builder.start();
    } catch (IOException e) {
        e.printStackTrace();
    }

    //get stdin of cmd
    BufferedWriter p_stdin = new BufferedWriter(new OutputStreamWriter(process.getOutputStream()));

    // execute the desired command from list
    List<String> cmdList = new ArrayList<String>();
    String baseURL= "abc@xyz.com/a/b";
    cmdList.add("cd c:
epproject");
    cmdList.add(String.format("git fetch -v --progress %s releaseBranch", baseURL));
    cmdList.add("exit");

    for (String cmd : cmdList) {
        try {
            //single execution
            p_stdin.write(cmd);
            p_stdin.newLine();
            p_stdin.flush();

            if(cmd.startsWith("git fetch")) {
                //process.waitFor();
                //p_stdin.wait();
                p_stdin.write("XXXXX@xxx");             
                p_stdin.newLine();
                p_stdin.flush();
            }

        } catch (IOException e) {
            System.out.println(e);
        }
    }
    Scanner scanner = new Scanner(process.getInputStream());
    while ( scanner.hasNextLine()) {
        System.out.println(scanner.nextLine()); //Process hangs at this point
    }
    process.getInputStream().close();
    scanner.close();
