Parameters

Branch to release.
Default value is master.

Version to release.
Default value is from POM snapshot.
NOTE: this will be the name of a new branch created from BRANCH (above) as well!

Next snapshot version to set (e.g. 1.2-SNAPSHOT).
Default value is from POM snapshot with last component incremented by 1.

-DdryRun=true is passed to Apache Maven when checked.

Allows to overwrite existing version in Git and Nexus staging repositories.

Should the specification version be updated as well?
If enabled, x.y-SNAPSHOT will be updated to x.y for the release and $NEXT_VERSION afterwards. The 'incorrect' version format is deliberate to act as a singal not to do a sepcification release from that branch.
It is assumed that the spec and API versions are aligned.
