+--release-snapshot [--gitCommitHash="a874b73"]
+Publish the maven snapshot artifacts to 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, branch name or commit to build from, default master HEAD
+--dryRun             - Dry run only, mostly used for testing.
+A GPG passphrase is expected as an environment variable
+GPG_PASSPHRASE - Passphrase for GPG key used to sign release
