Deduplicate Maven artifacts across multiple repositories

Is there any recommended ways to deduplicate maven artifacts across multiple repositories?

We have inherited a Nexus 3 Repository Manager where thre are lot of release artifacts duplicated across multiple repositories due to historical reasons and now we are facing issues with storage and have find a way clean them up.

We are option to any suggestion (even if its non standard scripting approach),


Built in cleanup procedures are documented here:
If your instance is old, recommend upgrading to get access to everything on that page for sure.

Likely what you want however is Until that is implemented you are somewhat limited to a date based approach. I am skeptical there’s a scripted solution (and not one I’ve heard of) but I could be wrong.

Hope that helps a little,
