!! Trying to register two bundles with the same name "EzMigrationBundle"
!!
Bundle name should follow naming convention https://symfony.com/doc/current/bundles/best_practices.html#bundle-name
The issue occurs when trying to install this bundle on sf4 using symfony flex,
https://github.com/symfony/flex/blob/master/src/SymfonyBundle.php#L89 https://github.com/symfony/flex/blob/master/src/SymfonyBundle.php#L103
code expects that the bundle file will follow namespace "Kaliop\eZMigrationBundle\" -> one of those:
0 => "Kaliop\eZMigrationBundle\eZMigrationBundle" 1 => "Kaliop\eZMigrationBundle\KaliopeZMigrationBundle"
