If you just want to delete one or two artifacts from Nexus, the web interface is fine. However, if you've got 30+ artifacts that you want to remove based on a certain criteria, e.g. their version, the command line is much faster.
I wanted to remove all artifacts which had given version (my build had
a very distinct version like
3.60-UNSTABLE.175403), so that I could
re-run the Maven upload target.
There were two trees in Nexus I needed to scan. The tree where the
meta information is stored and the one where the actual files are: I
included so much of the path to make find run faster (where it says
$ ssh nexus.example.com $ find \ /usr/local/data/nexus-work/storage/<repo>/.nexus/attributes/com/example/app \ /usr/local/data/nexus-work/storage/<repo>/com/example/app \ -name *3.6.0-UNSTABLE.175403* \ -delete
And of course, when trying the command out, remove the "-delete" part of the line first to see that you get the search hits you want, the include it on the consecutive run 😊
