Hi,
no interfaces are not supported for configuration, only annotations.
Main reason is the support of default values for configuration properties.
But you can pass in more arguments into the activate method, so instead
of having a base interface C and lets say two configuration interface C1
and C2 inheriting from C, you specify three annotations C, C1 and C2
where C1 and C2 only have the additional properties.
In your activate method you can then have two arguments C and C1 for one
component and C and C2 for the other component.

Hello all,
I have two components where the configuration shares a couple of
attributes. To avoid duplication, and because Java doesn't allow
annotations to be extended, I changed the configuration annotations to
interfaces.
When building, bnd-maven-plugin fails with the following error message:
Non annotation argument to lifecycle method with descriptor
I checked the specs and @ObjectClassDefinition can be applied to an
interface type.
Thank you
João
