OSGi instruction Include-Resource not working

According to the Bnd documentation an OSGi bundle is constructed from 3 different arguments:

Export-Package
Private-Package
Include-Resource

Using the Include-Resource instruction seems to have no effect on the resulting bundle.

This might be an documentation issue. My understanding is that Bnd uses the Include-Resource instruction to add e.g additional Java archives to an OSGi bundle. If Gradle proposes a different approach to allow the same than it would be helpful if this could be documented.
