After \r (without \n), output should overwrite the output in the last line, but it has the same effect as \n. Test case: public class MainApp { public static void main(String[] args) throws InterruptedException { while (true) { System.out.print("\r"); // no \n, no println System.out.print(java.time.LocalDateTime.now()); Thread.sleep(1000); } } } Output: 2017-05-24T12:17:30.740 2017-05-24T12:17:31.756 2017-05-24T12:17:32.756 2017-05-24T12:17:33.756 2017-05-24T12:17:34.772 and so on Expected output: A single line which is updated every second Building Maven projects is also affected. Without --batch-mode, the output window contains many lines like Progress (1): 4.1/34 kB Progress (1): 7.9/34 kB Progress (1): 12/34 kB Progress (1): 16/34 kB Progress (1): 20/34 kB Progress (1): 24/34 kB Progress (1): 28/34 kB Progress (1): 32/34 kB Progress (1): 33/34 kB Progress (1): 34 kB which should disappear because they also use \r.
