Oh, btw: eclipse == disaster (just kidding, I am also using Eclipse)

So this very much sounds like it could evolve into an URL handler, where
the URL might be something like src://.... and your builder gets the
package compiles and packages it and provides the InputStream to the result.

I am not even sure, this needs framework hacking: What you probable need:

  * Implement an URL Handler to handle the special source bundles
    being installed using special URLs
  * Use the PackageAdmin service to find packages and classes installed
    in the framework
  * Use OBR to find packages not installed in the framework in a
    remote repository (you probably don't want to install these
    dependencies unless you build a build-machine)

Sounds like an intereting idea, but:  Does this support automated builds
and publications ? How about end users ?

As for Apache: having source-only bundles is not a problem, because
(officially) the ASF only distributes sources [binaries are considered
