Sorry I'm a french native speaker, so i'll answer in english.

For some reason, sonata admin dependencies are bound to:

sonata-project/core-bundle (2.2.2)

Which does not upload the Resources/view directory.

Just do that:

C:\WORKSPACE\projects\site_maman>php composer.phar require sonata-project/core-bundle
Warning: This development build of composer is over 30 days old. It is recommended to update it by running "composer.phar self-update" to get the latest version.
Please provide a version constraint for the sonata-project/core-bundle requirement: dev-master
./composer.json has been updated
Loading composer repositories with package information
Updating dependencies (including require-dev)
- Removing sonata-project/core-bundle (2.2.2)
- Installing sonata-project/core-bundle (dev-master 6c5da36)

Installing assets using the hard copy option
Installing assets for Symfony\Bundle\FrameworkBundle into web/bundles/framework

Installing assets for Sonata\AdminBundle into web/bundles/sonataadmin

Installing assets for Sensio\Bundle\DistributionBundle into web/bundles/sensiodistribution

If it does not work go to the git website and download manualy
