Prepare release

The first step is to prepare the release. Make sure you are on master and up to date then run:

mvn release:clean release:prepare -DskipTests -Darguments=-DskipTests

This will do a number of things (let's assume you're trying to release version x.y.z):

build znaiblog
prompt you for a few version related things where you should generally accept the proposed values
update the version number in all poms to x.y.z
git commit the change
tag git as x.y.z
update versions to x.y.(z+1)-SNAPSHOT
git commit the change

Perform the release

export GPG_TTY=$(tty)
mvn release:perform -DskipTests -Darguments=-DskipTests

This will prompt you for the GPG passphrase. It will then build and test znaiblog and publish all artifacts to Maven Central.
