Modify the build so that artifacts can be released into Maven Central via the Sonatype OSSRH repository manager. In particular, this includes satisfying all of the requirements to use the repository manager (e.g., DBZ-12), and to put the information into the POM so that artifacts are uploaded correctly.

Once the build system is configured, releasing a version involves using Maven to deploy the project into a staging repository, logging into OSSRH, and releasing the deployment and dropping the staging repository (see also this documentation).
