Update Version

Releasing

Create a new branch called release/X.Y.Z
git checkout -b release/X.Y.Z
Change the version in gradle.properties to your desired release version (see Update Version)
git commit -am "Create release X.Y.Z." (where X.Y.Z is the new version)
git tag -a X.Y.Z -m "Version X.Y.Z" (where X.Y.Z is the new version)
Upgrade to next version by changing version in gradle.properties
git commit -am "Prepare snapshot X.Y.Z-SNAPSHOT"
git push && git push --tags
Create a PR to merge the new branch into master
The CI pipeline will recognize the tag and upload, close and promote the artifacts automatically, and generate changelog automatically

Current VERSION_NAME in gradle.properties = 1.3.0
git checkout -b release/1.3.1
Change VERSION_NAME = 1.3.1 (next higher version)
Update CHANGELOG.md
git commit -am "Create release 1.3.1
git tag -a 1.3.1 -m "Version 1.3.1"
git push && git push --tags
Change VERSION_NAME = 1.3.2 (next higher version)
git commit -am "Prepare snapshot 1.3.2-SNAPSHOT"
git push && git push --tags
Merging PR master will create a snapshot release 1.3.2-SNAPSHOT and tag push will create stable release 1.3.1
