@Thorsten.
OK I didn't realise there was 'more' to the .deb and .dsc stuff... I'm sure I mentioned that I'm a newbie to packaging 😉 (scratches head).
@Emmanueal
The team already has a gradle.build for windows and OSX, so I don't need to worry about those.
The truth is that the gradle.build is actually installing to a virtual machine (vagrant). The rpms are just... well... RPMs hence RedHat / CentOS centric.
It just seemed a bit crazy to have a VM on my debian jessy box that ran CentOS, so as I could build a Vagrant VM inside of that... just too many levels of abstraction for my head to get around !
