Additional context
E.g. testerra-appium-connector does not have this issue.

The issue is caused by this setup:

• MMS-internal init.gradle defines a default repository
• this project does not define any repositories
• gradle build will fail dependency resolution unless some project-external configuration (e.g. a foreign init.gradle) provides default repositories

The issue can be fixed by the following setup:

• this project should define publicly accessible repositories (most famously maven-central)
• MMS-internal init.gradle should define a mirror for maven-central pointing to our internal repository (which indeed does mirror maven-central)

=> public users will use maven-central, MMS coworkers will use MMS-internal repository, everyone can build the project.
