Question about buckminster and headless [message #536170]

Hi
I have following questions:

Which compiler is used by buckminster headless - java or eclipse?
------------------
How can I build more projects with dependency to a generated .jra file?
example:
project A (osgi.bundle)
project B (osgi.bundle)
project C (source with ant-task to generate jar file)

project A has a dependeny to B and B needs jar-File from C

so in project A a have a 'required plug-ins dependency' generated in MANIFEST.MF

How can a form a dependency in B to jar from C
How can I perform automatic ant-build if necessary?

------------------

any ideas?
Rainer

Eclipse Java Compiler, Eclipse Bundle Manifest Compiler, Eclipse Schema Compiler, etc. Buckminster builds exactly the
same way that your IDE does.

Is it possible for you to turn C into an osgi.bundle? If you do that, you're all set. All dependencies will be honored
automatically. Both when you populate your workspace/target platform, and when you build.

If that's not possible, then you can add a buckminster extension (buckminster.cspex) to the B bundle that appoints the
component C. In C, you add a buckminster.cspec that describes what C provides (i.e. the jar).

You can call the ant-task either using an ant action in the cspec or using an Eclipse Builder. You'll find more
information in the Buckminster documentation:
