Are there any ways to make javac use an existing OSGi-environment for the resolution of build-time dependencies instead of setting the classpath explicitely? I know I could write an OSGi-component that uses the Compiler-API of the JDK, but I think there should be a more straightforward solution.
Alternatively, if no such extension is available for javac, does ejc allow such a thing (usable from the command line; I'd be willing to accept an Equinox-only solution with ejc)?

Have you considered using Maven to manage dependencies? There are plugins available for IDEs like Eclipse. You just need to map the resource servers, and the needed libraries in a pom.xml, and that is pretty much it.

You're missing out on the one obvious Java compiler that follows OSGi rules - Eclipse.
You can use Eclipse's compiler to do a headless build, but be warned, it's not for the faint-hearted.
Here's a simple tutorial on building with Eclipse and ant.
If you go down this path, I'd suggest looking at Tycho (the Maven sub-project for building OSGi stuff) and Buckminster, an Eclipse project.

I'm developing in the Lotus Expeditor Toolkit and Eclipse Plugin - It's a no-charge download. My build time and runtime classpaths are managed very easily by entries in the Manifests.
