How to build the starter locally

Doing a full .mvnw clean install fails, because I am missing the ee snapshots.

I have setup a settings-camunda.xml that I use via .mvn/maven.config … but it seems that it’s not enough to set


a) What is the ee-snapshot repo?
b) is documentation available how to set up a local build? I only saw the and that was rather vague.
b*) if not: I would like some docs …
b**) alternative: provide profiles for ee builds that are excluded by default or document how to run a local build excluding those modules.
