You need to add the same entry in the CI to check SF7 is installed correctly.

Also, we will need to add support for those lib first: https://github.com/sonata-project/SonataMediaBundle/blob/4.x/composer.json#L88-L91

I added support for SF7 on

• SonataBlockBundle
• SonataAdminBundle

For SonataDoctrineORMAdminBundle we need AuditBundle which need the DoctrineExtensions
For ClassificationBundle we need SonataDoctrineORMAdminBundle
