Hello Alexander,
Things can get quickly hairy with Java packaging, and when coupled with
Maven, you'd better have more a just a passing familiarity with Maven...
mh_make tries to make the heavy lifting for you, but it's never perfect
and I find always new cases, like yours.
With a more recent version of mh_make, I have been able to get a bit
further, but not by much. I will try to keep improving the tool for
those use cases.
Using the --no-parent option is something that is tricky. In some cases,
it's quite harmless to do, as the parent only contains some developer
information, license, defaults for some plugins which can be ignored,
but in your case the parent contains important information
(dependencies) which cannot be ignored. So you need to package as well
the parent POM.
Now it seems useless to create a package for a single file (and the FTP
team will not like you for doing so), so you need to include this file
in your package. You can either copy it in the debian/ folder, or you
can use the technique of source packages with multiple upstreams. I'm
using it, and it rocks.
I'm sending you my work in progress on this package. There is one
troublesome dependency remaining: it's ic4j, and the version used by
Jena is 3.4.4, while versions 4.0, 4.2 and 4.4 (!) are packaged in
Debian. Maybe you can suggest upstream to do an upgrade or patch the
package to make it work with a new version of this library.
Hope this helps,
Ludovic
