This form execute maven release:prepare and upload the release candidate distribution
to the staging release location.

--release-publish --gitCommitHash="a874b73"
Publish the maven artifacts of a release to the Apache staging maven repository.

--release-snapshot [--gitCommitHash="a874b73"]
Publish the maven snapshot artifacts to Apache snapshots maven repository

OPTIONS

--releaseVersion     - Release identifier used when publishing
--developmentVersion - Release identifier used for next development cyce
--releaseRc          - Release RC identifier used when publishing, default 'rc1'
--tag                - Release Tag identifier used when taging the release, default 'v$releaseVersion'
--gitCommitHash      - Release tag or commit to build from, default master HEAD
