Actually I think you are way better of if you use the spring enterprise repository.
http://www.springsource.com/repository/
There is not only the spring distribution available, but also many other libraries, with correct dependencies to each other (which is not the case for the official maven repositories!). Further, it is also an OBR, so every library is also already an OSGI bundle!
