Create a scheduled task to purge out old snapshots.
The following links describe the functionality:
- Nexus scheduled tasks
- Managing scheduled tasks – Repository Manager 2
- Types of Tasks and When to Use Them – Repository Manager 3 (Task “Maven – Delete SNAPSHOT”)
You can configure the task to always keep a minimum number of artifacts. It’s very flexible.
The only “gotcha” in Version 2 of the Repository Manager, is that you’ll need to also run a second task, Empty Trash, in order to claim back the disk space. For Version 3 you will need to run Compact blob store to ensure that the deletion will return the disk space. See docs above.
