So you need to have created a PGP (or GPG) key pair, which will be used in signing the release artifacts. For more information on using the Maven GPG plugin, see this introduction from Sonatype and the Maven GPG Plugin usage page. You may also want to run gpg-agent in order to avoid being prompted multiple times for the GPG key passphrase when performing a release.
