java - How to limit number of deployed snapshots artifacts in Nexus?

Question

We are using Nexus to deploy our snapshot artifacts. Our build server deploys them during each build using the following command: mvn deploy. As result on each build the newer version of the artifact is deployed. The problem that already about dozens of artifacts are deployed to the repository and of course we need only the last artifact. Is any way to limit number of deployed snapshots artifacts in Nexus? Thanks for your help, Michael

Answer 1

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.
