How to make a release with Git and Maven via JGitFlow

Imagine that you are versioning your sourcecode in git and building your code via maven. You need to make releases before deploying to production regularly. What should be the strategy we need to follow for releasing?

I've used maven-release-plugin for years to make releases. It worked perfectly with maven and svn, but we started to face problems when we migrated our code to git and to make releases on git.

After checking the literature, we decided to use JGit-Flow which is a maven plugin based on and is a replacement for the maven-release-plugin enabling support for git-flow style releases via maven.

I do not want to explain the details much because there are many great posts explaining all.

Code is clean if it can be understood easily – by everyone on the team. Clean code can be read and enhanced by a developer other than its original author. With understandability comes readability, changeability, extensibility and maintainability.

General rules

1. Follow standard conventions.
2. Keep it simple stupid. Simpler is always better. Reduce complexity as much as possible.
3. Boy scout rule. Leave the campground cleaner than you found it.
4. Always find root cause. Always look for the root cause of a problem.

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>
