Maven repository snapshot pruner

This is a Java application that will traverse a maven repository directory hierarchy and delete all deployed snapshot artifacts except for the snapshot version currently in the maven-metadata.xml files.

The program is intended to clean up snapshot repositories created with “mvn deploy” either using “file:” or “ftp:” URLs, and is intended to be run as a cronjob.

Status

Installation on a debian system

1. Install the prerequisites

   apt-get install git maven default-jdk
       

2. Clone and build the repository snapshot pruner

   cd /var/www-maven/
   mkdir -p .m2
   chown -R maven.maven .m2
   git clone https://github.com/steinarb/maven-repository-snapshot-pruner
   chown -R maven.maven maven-repository-snapshot-pruner
   cd maven-repository-snapshot-pruner
   sudo -u maven git config pull.ff only
       

3. Run the pruner once a day as that user (in the example the user with the username “maven” is used:
   1. Run this command as root

      sudo -u maven crontab -e
              

   2. In the editor that is opened add the following line (the “>/dev/null” is to avoid nightly emails, remove it if more debugging is needed):

      55 23 * * * cd /var/www-maven/maven-repository-snapshot-pruner; git pull >/dev/null; mvn compile exec:java -Duser.dir=/var/www-maven/repository >/dev/null
