Nexus-Cleanup

Remove old releases from a Maven2-repository in Nexus3

This Groovy-script will purge old versions (sorted by version-number) from a maven repository hosted on Nexus 3.x.

You can set the desired repository and a maximum amount of versions at the begining of this script.

Optional: define a retention (in days), so that old versions are only deleted if they are older than the retention.

Information

After upgrading from Nexus 2.x to Nexus 3.x, the build-in function for keeping the latest X releases was sadly gone. Ofcourse there is an ongoing feature-request for that.

I tried the script by Matt Harrison from StackOverflow for this problem, but the migration-tool in Nexus had reset all last_updated-values to the date of the migration, sad again.

Now I tried to sort the releases by version via 'ORDER BY version DESC', but that resulted in a mess, where a version 3.9.0 is newer than 3.11.0 and so on, not a suitable scenario.

In the end, I forked Matt Harrison's script and the nice logoutput by Neil201

Added some helper-lists and the VersionComperator (a version sorter) by Rob Friesel

Finally, I linted the script with npm-groovy-lint to get a cleaner code, somehow

I later included the retention-feature kindly provided by agronlun and some cleanup/optimization by emetriqChris

Installation

  1. add the line nexus.scripts.allowCreation=true to $data-dir/etc/nexus.properties
  2. restart the Nexus-service, to apply the changes
  3. in the webinterface of Nexus, go to Administration > Tasks and create a new Execute script-task
  4. configure the task by filling out the required fields (Task name, Task frequency, etc.)
  5. copy 'n' paste all lines from nexus-cleanup.groovy into the Source-field
  6. disable further script creation, by adding a leading #-character to the line from step 1.
  7. restart the Nexus-service, once again

More information about setting up custom scripts, can be found in this article from the Sonatype Support Knowledge Base.
