Docs feedback: GitLab CI/CD Examples: Clojure

I would like to refer to (Test a Clojure application with GitLab CI/CD)[https://docs.gitlab.com/ee/ci/examples/test-clojure-application.html]. However, it misses several interesting points:

• how do I deploy the resulting artifact from this project to the Gitlab Maven repository (ok, I'm using gitlab.com, so maybe it's a different issue)
• how do I integrate Code coverage (e.g., from (lein cloverage)[https://github.com/cloverage/cloverage] to actually show up in Gitlab Code Coverage reports.
