The as far as I know relevant dependency packages seem to be included in
the jar-file. Tried with unzip -l:
$ unzip -l target/dokpool-faq-importer.jar
Archive: target/dokpool-faq-importer.jar

Generally classloaders will only load classes from within a jar, not
jars-within-jars.
If you want to only have a single jar with everything in, you'll either
need to switch to a more "war-like" classloader to have jars within your
jar loaded, or use something like shading/shadowing when you build the jar
to have the classes of the dependencies in-lined within your jar
