/**
 Applies a consistent versioning scheme to all projects using this script
  -PreleaseVersion=0.2.3.4 will set the jar version to 0.2.3-4

  Not providing a property will make it use git tags to mint either a version like:
  0.8.44 or 0.8.44-1 (for clean tags) or 0.8.45-SNAPSHOT (for unclean repositories)
