This also happened to me a lot. If you use the current 6.0.0 OSGi specs and the maven-bundle-plugin 3.0.0 it will automatically create a Requirement for the DS extender. If you then install your application using a feature then karaf will complain if the DS extender is missing.
This does not work though if you install individual bundles.
