Backup

Create assembly configuration file backup.xml

descriptorRef src

Package the source code in a zip file

mvn clean assembly:single -Ddescriptor=src/main/assembly/backup.xml -DfinalName=${project.artifactId} -DoutputDirectory=${user.home}

add .gitignore to mandatory empty directory

# Ignore everything in this directory
*
# Except this file
!.gitignore

Configure the Package Clean UP Automation with GitHub Action

The Action run during the release phase of package (or you can run it manually). Leave only the latest package version into the repository. Create the .github/workflows/cleanupPackages.yml file.
