Re: [cbi-dev] Some feedback on the build prototype

[Igor Fedorenko <igor@xxxxxxxxxxxxxx>]

This is not how Tycho, and Maven in general, work. As I mentioned
before, Tycho builds source trees, which in virtually all cases consist
of multiple related projects (or "modules", as in Maven speak) that are
developed and built together. In case of git, this means that all
modules' sources belong to the same checkout.
