How to Sign and Release to The Central Repository with GitHub Actions
GitHub allows automated builds using GitHub Actions. A commonly asked question is how to release artifacts (packaged Java jars) built by Maven and Gradle to The Central Repository. The GitHub Actions documentation provides only part of the answer.
So, first, configure your Maven project for staging artifacts to The Central Repository, by reading through Configuring Your Project for Deployment and following those steps. Please make sure that the maven-gpg-plugin is configured to prevent
gpg from using PIN entry programs, as follows:
<configuration> <gpgArguments> <arg>--pinentry-mode</arg> <arg>loopback</arg>
