To launch programs from my Python-scripts, I'm using the following method:
def execute(command): process = subprocess.Popen(command, shell=True, stdout=subprocess.PIPE, stderr=subprocess.STDOUT) output = process.communicate() exitCode = process.returncode if (exitCode == 0): return output else: raise ProcessException(command, exitCode, output)
So when i launch a process like
Process.execute("mvn clean install"), my program waits until the process is finished, and only then i get the complete output of my program. This is annoying if i'm running a process that takes a while to finish.
Can I let my program write the process output line by line, by polling the process output before it finishes in a loop or something?
