An OSGi bundle is just a jar file with extra metadata in its MANIFEST.MF
file. These metadata define the name of the bundle, the Java packages it
depends on and the Java packages it exports. This information is used by
an OSGi framework to wire the bundles and isolates the classpaths.

maven-debian-helper supports both CDBS and DH. Historically CDBS support
was implemented first so we have a lot of packages using it, but we are
gradually migrating them to DH.
For a Maven build prior to DH 10 you would use in debian/rules:
dh $@ --buildsystem=maven
Starting with DH 10 Maven builds are automatically detected and the
--buildsystem parameter is no longer required (except if there is also
an Ant build.xml file in the root directory).
mh_make generates DH style rules files since the version 1.7 (in stretch
and jessie-backports).

There is also maven-repo-helper that can be used to install Maven
artifacts in a package not build with Maven:
dh $@ --with maven-repo-helper
This will install the artifacts defined in debian/<package>.poms

Did you ignore the maven-bundle-plugin? If so you have to change the
packaging type in the pom.xml files from 'bundle' to 'jar'. But enabling
the plugin should be straightforward.

By asking for help to the Java Team ;)
