Naming conventions (For domain objects)

I am using the publishing plugin and to create a publication I need to create a domain object with a name.
So far I have been using the kebab-case convention extensively, but I have come across this inconsistency:

Similarly, I am seeing kebab-case as well as normal names for projects set via rootProject.name.

Is there a resource on naming conventions in Gradle? I am trying to be consistent across my projects but seeing inconsistencies like seen in the picture above is a bit annoying.
