Hi @shijiyong_6709 ,

This is a known limitation; when we implemented our Maven2 feed, we followed the 20+ year old Maven rule that "versions begin with numbers, artifacts begin with letters". Unfortunately there are some "ancient artifacts" and "broken versions" that don't follow this rule.

Since ProGet is not just a "dumb file server", knowing whether Arabba-SR13 is a version or artifact is important - and it's a nontrivial effort to address these "bad" artifacts. We will consider doing that in the future but it doesn't seem to impact a lot of artifactsa nd hasn't been a priority

Thanks,
Steve
