--- Comment #2 from Robert Scheck  ---
As mentioned in bug #2000976, I'm not experienced in Java (packaging), I've
read https://docs.fedoraproject.org/en-US/java-packaging-howto/manpages/, and
I'll try to review this...hopefully.
> %pom_xpath_inject pom:project '<groupId>com.github.stefanbirkner</groupId>'

> %pom_add_dep org.apache.commons:commons-lang3
> %pom_xpath_inject 'pom:project/pom:build/pom:plugins/pom:plugin[pom:artifactId="maven-surefire-plugin"]' '<version>any</version>'

Why are these POM changes needed? Does it make sense to put the
reason/explanation into comments inside the spec file?
