This project follows the gitflow model, so we have develop as development branch and master as production branch.
In order to release this project, you must execute from develop (with latest changes) the following command:
mvn -B gitflow:release-start
Then, all the suffixes -SNAPSHOT will be removed and the release/X.X.X branch will be created, so then you must execute:
mvn -B gitflow:release-finish
So in develop, the version of the poms will be incremented automatically and master will contain the release branch merged and the tag created.
For more information about how it works the plugin (options, parameters, etc) please refer to this link.
Remember to push the commits to develop and master
