LGTM, @ilooner please double check that Apache source distribution can be
built with '-Drat.skip=false -Dlicense.skip=false':
- build with `-P apache.release -Dgpg.skip=true`
- extract created source .tar.gz or .zip to a temp directory
- build with apache-rat and license check enabled (you may need to add more
files to the license check exclusion).---
