maven-repository-snapshot-pruner

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.
