        <!-- This POM uses the classic maven-deploy-plugin. We could alternatively use Sonatype's Staging Plugin
             which can by-pass the UI action. When we use the classic maven-deploy-plugin it will be required (after
             deployment has executed) to go into the Sonatype UI and release the artifact bundle.
             Once you become confident with the workflow, you can switch to the Sonatype Staging plugin instead. -->

        <!-- Maven prior to v3.9 uses version 2.x of the deploy plugin and after this use v3.x of the deploy plugin.
             We use the 'altReleaseDeploymentRepository' and 'altSnapshotDeploymentRepository' properties
             so best to use v3.x of the plugin -->

      <!--  Javadoc here because we want to know early if there are errors in Javadoc generation.
            In the standard Sonatype guidelines it is inside the 'release-to-central' profile
            which means we will not discover Javadoc errors until we decide to release.
            Instead, we pay the price of Javadoc generation on every commit: an acceptable tradeoff.
