Sonatype's instructions for releasing Maven projects have changed since this project was configured to do so.

In particular:

• The oss-parent POM is deprecated
• They recommend use of the Nexus Staging Maven Plugin

I'm so happy you linked to this documentation. I had no idea that oss-parent was deprecated nor that the documentation at https://central.sonatype.org/publish/publish-maven/ even existed. I guess it's time to update all my projects.

PS: A new version of the staging plugin just came out. Be sure to update to it to avoid a host of bugs and vulnerabilities. See https://github.com/sonatype/nexus-maven-plugins/pull/91

Yeah, I just went digging up that documentation because I had honestly forgotten how to release to the OSSRH server.
