Thank Jesse . Meanwhile i tried something like . created a ListenerLogDecorator class which extends LineTransformationOutputStream and in the perform method i called it like below
ListenerLogDecorator outStream = new ListenerLogDecorator(listener); launcher.launch().pwd(workspace).cmds(constructDefaultCommand()).stderr(outStream).join(); the decorator class contains one overridden method like below. protected void eol(byte[] bytes, int length) throws IOException { if(this.listener == null){ return; } String line = new String(bytes,0,length,Charset.defaultCharset()); this.listener.write(line.getBytes(Charset.defaultCharset())); } On Monday, 8 October 2018 19:48:06 UTC+5:30, Jesse Glick wrote: > > On Sun, Oct 7, 2018 at 3:30 AM Nikhil Bhoski <nikhil...@gmail.com > <javascript:>> wrote: > > i want to keep error strem and send that to listener > > That is what happens by default.
