Automatic creation and storage of build artifacts

Not sure what to call this, but here is what I am looking for. I have a build system that builds 3 sets of components - server components - desktop components - device components Each have their own build scripts, with an overall one that builds them all and creates a package with all 3 together. The issue is when I build a package, I would like to not have to build all 3 sets, I would like only the sets whose source has changed since the last time a package was created. As each component can take quite some time to build, and a developer usually only ones the set he's working on to build, but needs them all to test.

I would like to be able to request the latest package, which comprises the latest binaries of the most up to date source. Would also like to be able to request, the package that was built for build 195, lets say.

I saw a Google Tech Talk that shows that Google does this in house. I have found http://arch开发者_如何学Civa.apache.org/, but it seems to simply be a storage mechanism. Maybe Bamboo already does this and I have not been able to see it?

I have been unable to find the right search phrase for Google to give me an answer.

So turning to you all to see what I might find, thank you in advance.

Sounds like something you could do with Ivy dependency management.
