Java终端/ CMD交互

我要做的是让我自己的java程序通过命令行/终端与pianobarfly(https://github.com/nega0/pianobarfly)进行交互。此时我似乎可以启动应用程序,但只有第一行是通过java打印出来的。它似乎没有认识到后面的界限。我该怎么做呢?

    import java.io.*;

class mainA
{
    public static void main (String[] args) throws java.lang.Exception
    {
       try {
           Process p = new ProcessBuilder("/Users/sbuck1994/Desktop/pianobarfly-master/pianobarfly").start();
           BufferedReader input = new BufferedReader(new InputStreamReader(p.getInputStream()));
           BufferedWriter output = new BufferedWriter(new OutputStreamWriter(p.getOutputStream()));
           String resultLine = input.readLine();

           while (resultLine != null) {
             System.out.println(resultLine);
             resultLine = input.readLine();
           }

           int exitVal = p.waitFor();
           System.out.println("Exited with error code "+exitVal);

       } catch(Exception e) {
           System.out.println(e.toString());
           e.printStackTrace();
       }
    }
}

这导致:

当我认为它应该打印出这样的东西时:
