External processes via groovy script

Had one problem one trying to kick off an external process from a groovy script. Actually two problems:

1. Not getting desired output from process (java process with INFO logging)

Solution:

process.consumeProcessOutput(System.out, System.err)

Add that method to your process that you want to kick off and it will print the stuff you want.

2. Could not build up my argument list correctly

Well I had laborated with a linux command like """ping -c 2 localhost""" and it worked like a charm to just add """my command""".execute(). However when I started to get the arguments passed from another script they got separated.

My solution was like this:

Build up the strings again and then use ProcessBuilder. Like this:

def process = new ProcessBuilder(command).redirectErrorStream(true).start();

Where the command is a ArrayList with combined parameters. Like:

def command = []

command[0] = "ping"

command[1] = "-c"

command[2] = "2"

command[3] = "localhost"

Could probably be used nice but for this time it worked nice.
