# Notes about maven project version:
# - Decided not to use it in tags since we rarely update it.
#   Using branch, timestamp, and commit info in the tag names makes more sense for now.
# - Originally wanted to use maven to get version but help plugin is too slow:
#   MAVEN_PROJECT_VERSION=$(mvn help:evaluate -Dexpression=project.version -q -DforceStdout)
# - Switched to xmllint since that was much faster:
#   - xmlns in root pom project element screws up xmllint, so use sed to crop it all out first
#   MAVEN_PROJECT_VERSION=$(sed 's/^<project.*/<project>/' pom.xml | xmllint --xpath "/project/version/text()" -)  # 4.0.1-SNAPSHOT
#   MAVEN_PROJECT_VERSION_NUMBER="${MAVEN_PROJECT_VERSION%%-*}"                                                    # 4.0.1
