GitLab CE Maven Package Registry

We would like to publish Java library to GitLab package registry. Our build tool is gradle.

With personal access token - the artefacts are uploaded to the registry. Eg: from the gradle debug:

Performing HTTP PUT: https://gitlab.com/api/v4/projects/15962804/packages/maven/com/flexvoucher/skeleton/1.0.1-SNAPSHOT/skeleton-1.0.1-20201002.083824-8.jar

is working. I can curl this URL and download the artefact.

But … I can not see it in the GitLab CE GUI in the Project Package Registry. Nothing to see there …

Any hints are appreciated.

Thank you.
