Well, bnd thinks "packages" so there is no support for class based filtering.
That said, you might try:
b1.jar:
Include-Resource: \
@a1.jar!/!p/q/r/Foo*.class, \
@a2.jar!/!p/q/r/Foo*.class
-exportcontents: p.q.*
b2.jar
Include-Resource: \
@a1.jar!/p/q/r/Foo*Impl.class,
@a2.jar!/p/q/r/Foo*Impl.class
There is one other possibility, -donotcopy ... It is intended for skipping
.svn, CVS, etc resources. It is global and it is a REAL regular expression (not
the normal globbing).
<_donotcopy>.*Foo.*\.class|CVS|.svn</_donotcopy>
Haven't tried that though ...
The disadvantage is that Include-Resource requires access to the raw jar and I
guess you want it from the classpath because you're running this in maven. I
could if you really need this add a feature to bnd that allows resource
filtering on the Private-Package, Export-Package, and Conditional-Package.
Kind regards,
