I did it this way:

gcube_repository: 'gcube-staging'
smartgears_gcube_repository: '{{ gcube_repository }}'

smartgears_global_base_url: 'http://maven.research-infrastructures.eu/nexus/content/repositories/{{ gcube_repository }}'
smartgears_url: 'http://maven.research-infrastructures.eu/nexus/content/repositories/{{ smartgears_gcube_repository }}/org/gcube/distribution/smartgears-distribution/{{ smartgears_distribution_version }}/{{ smartgears_file }}'

So, the compatibility with the actual configuration is ensured.
If you want smartgears from staging and other parts from snapshots you now need to redefine both:

gcube_repository: 'gcube-snapshots'
smartgears_gcube_repository: 'gcube-staging'

If you want all from shapshots, you only need to redefine gcube_repository as we always did.
