Thanks!

Oh actually, I think we need a similar fix to mockito/mockito-kotlin#425 where we have to drop the tags-ignore from line 13 and match on tags of 3.*

Did they degrade so much recently? It's true that the search index is updated after a few hours, but when I checked it a year ago (or so), the artifacts were available in https://repo1.maven.org/maven2/... (and ready for usage in Gradle/Maven/...) after a few (maybe several) minutes.

You can check that with the next Mockito release and update that statement if needed (e.g. to change the hours to minutes :) ).

Sounds good!
