But thanks for the quick and helpful response.

Can someone explain what these osgi 'bundles' are? How does that
relate to the .jars I am familiar with? The same stuff packaged up in
a different format? Who uses those? Are they any use in Debian packages?

Is it right to be using cdbs (to drive mh*), when dh (driving mh*) is
generally preferred these days? I don't mind cdbs personally, but
wonder if this is optimal - is that just what mh_make defaults to?
it is that there is no such thing as dh --with-maven-helper yet?

I presume that a proper packaging of javolution would include the
native library, although I don't actually know if the depending
project (jscience) uses it. It seems to only mention javolution.jar
(and builds if that is supplied), so I guess that I can get away with
just that part for now.

Doing this doesn't make it build. It still fails with:

Well I don't mind doing this if it's not too hard, and I don't have too
many more layers of java-package rabbit-hole to go :-).
That bug says "I left the packaging work I was doing up on
git.debian.org", but I can't find it.
There is a 2009 https://anonscm.debian.org/cgit/users/twerner/maven-native.git
which I think is an earlier version of the same package
but doesn't have a debian dir, so I guess torsten didn't get very far.
I'll mail Andres Mejia for clarification, but if anyone knows where
existing work might be...

Yep - that worked. How could I have worked out myself that
complaints about apache.felix meant I wanted that package?
