A Bash script updating the version of a Maven project accordingly the git-flow branching model.

This script accepts semantic versioning syntax as MAJOR.MINOR.FIX[.HOTFIX][-SNAPSHOT]. Acceptable examples are:

• 1.0.0
• 1.0.0-SNAPSHOT
• 1.2.3.4
• 1.2.3.4-SNAPSHOT

To calculate next version, the script asks what are the changes introduced. For example, given a current version as 1.0.0.1-SNAPSHOT:

• hotfix: new version will be 1.0.0.2
• bugfix: new version will be 1.0.1
• feature: new version will be 1.1.0
• breaking change: new version will be 2.0.0
• release: new version will be 1.0.0.1 (remove the SNAPSHOT tag)

Last check is if this version is under development (snapshot) or not. If yes, the "-SNAPSHOT" suffix is added to the calculated version.

Update the POM_PATH variable specifiyng your project POM path.

Simply run the script:

$ ./update-pom.sh
