It sounds like the Knopflerfish OSGi plugin doesn't like embedded jars,
and is automatically updating the manifest whenever anything changes
in the project (which may be why using bnd didn't work).

This is not really the best place to resolve this, as this is the general
OSGi mailing list - info at knopflerfish.org would be more appropriate.

That said, you might want to try creating a new plugin (PDE) project
using Eclipse 3.2 (without KF OSGi plugin!) or perhaps a new Java
project (again without the KF plugin) using the instructions at:


I've successfully built and deployed bundles containing jars, so it
is definitely possible, but I've only done this using Eclipse / Bnd.
