expectation

Works as with sbt 1.9.3 or older, which uses coursier 2.1.0 afaik: sbt/sbt@d516920

notes

Probably the corresponding pom with the tag <package>atlassian-plugin</package> confuses coursier?

Thanks for having a look.
And let me know, if I provide more infos.

Previously reported: sbt/sbt#7407

I can confirm the issue with sbt 1.9.7 and atlassian repository
