Re: How to manage enviroments & repositories whit Maven 2 ?

[Kalle Korhonen <ka...@gmail.com>]

I haven't used, and documentation is scarce as always, but couldn't you use
the artifact's classifier element for this? So, basically your option b),
but use either develop, integration, test or production as the artifact
classifier. More at least here:
http://docs.codehaus.org/display/MAVENUSER/Improving+Maven2+Dependency+Resolution.
Probably requires some googling from your part, but I recall seeing it in
use at least in one case.
