@Erik Parmann​ , I was gonna download the latest version of databricks-connect, but then I noticed the following on the help pages (Azure):

Databricks recommends that you use dbx by Databricks Labs for local development instead of Databricks Connect. Databricks plans no new feature development for Databricks Connect at this time.

So I went to the dbx page and noticed:

dbx execute can only be used on clusters with Databricks ML Runtime 7.X and only for Python-based projects.

So I guess scala users have to wait.
