All of these dependencies should be in the runtime scope, but it appears that the default maven plugin doesn't include the dependencies in the compile configuration by default in the runtime scope, see this thread
The behavior is expected. Parent configurations won't be considered when mapping configurations to scopes (doing so wouldn't work for 'compile' and 'runtime', for example). I recommend to change the way you share common dependencies, but I'd have to know/see more about your current solution to give concrete recommendations.
Experimenting locally with the maven-publish plugin gives promising results
