Maven Version Bump Action

A simple GitHub Actions to bump the version of Maven projects.

When triggered, this action will look at the commit message of HEAD~1 and determine if it contains one of #major, #minor, or #patch (in that order of precedence). If true, it will use Maven to bump your pom's version.

For example, a #minor update to version 1.3.9 will result in the version changing to 1.4.0. The change will then be committed.

CHANGES

• POMPATH should include pom filename
• -DgenerateBackupPoms=false -DprocessAllModules --file "${POMPATH}" added to mvn
• support prefix for version TAG
