Follow these steps when preparing a release
Note - the maven release plugin is used for managing releases.
This plugin requires that releases be performed from a -SNAPSHOT version.
Therefore, pom version numbers should be managed exclusively via the release plugin.
Assuming this is the first release of a new release set -- eg., x.x.0 release:
mvn release:branch -DbranchName=rel-1.0
Note - the naming convention for branches is rel-x.x. Point-patch releases (the z in x.y.z) are not included in the branch name.
mvn release:prepare -Darguments=-DskipGpgSigning=false
mvn release:perform -Darguments=-DskipGpgSigning=false
Then log on to https://oss.sonatype.org/index.html#stagingRepositories -> Filter to The Mango Factory, and close the listed repo.
Finally, release the Mango Factory repo.
