Yes, JniHeaders indeed has no type -- which is fine. But then, you're
adding it as sources of the 'lib' target, and the 'lib' target has no
idea what to do with targets of unknown type.

Probably, instead of adding the target to sources, you can use

        <dependency>JniHeaders

in requirements?
