# update-version.sh
# Created by Steve Hannah.  March 24, 2021
#
# Synopsis:
# ---------
#
# Updates the version of this project and commits the version changes in Git.  If the version
# is a release version (i.e. not ending in '-SNAPSHOT', then it will also add a git tag).
#
# Typically you would run this before and after running the deploy-to-sonatype.sh script.  Before
# to set the release version, and after to change to a new SNAPSHOT version.
#
#
# Usage:
#  bash update-version.sh VERSION
#
# Arguments:
#  VERSION    The version number to update to.
#
# Examples:
#  bash update-version.sh 8.0.1
#     Updates to version 8.0.1
#
#  bash update-version.sh 8.0.2-SNAPSHOT
#     Updates to version 8.0.2-SNAPSHOT
#
# Typical Workflow is:
# bash update-version.sh 8.0.1 && bash deploy-to-sonatype.sh && bash update-version.sh 8.0.2-SNAPSHOT
