Symfony/SonataUser - Error with abstract method of BaseUser

Question

I'm trying to install SonataUserBundle so I followed documentation (& use EasyExtendBundle but I get this error:

[Symfony\Component\Debug\Exception\FatalErrorException]                                              
  Error: Class Sonata\UserBundle\Entity\BaseUser contains 35 abstract methods and must therefore be declared abstract
   or implement the remaining methods (FOS\UserBundle\Model\UserInterface::setUsername, FOS\UserBundle\Model\UserInte
  rface::getUsernameCanonical, FOS\UserBundle\Model\UserInterface::setUsernameCanonical, ...) 

I did not change anything from the User entity generated by EasyExtends...

Config looks good:

fos_user:
    db_driver: orm
    firewall_name: main
    user_class: Application\Sonata\UserBundle\Entity\User
    group:
        group_class: Application\Sonata\UserBundle\Entity\Group 
        group_manager: sonata.user.orm.group_manager
    service:
        user_manager: sonata.user.orm.user_manager

My composer:

"symfony/symfony": "2.8.*",
...
"friendsofsymfony/user-bundle": "~1.3",
"sonata-project/admin-bundle": "~2.2",
"sonata-project/doctrine-orm-admin-bundle": "~2.3",
"sonata-project/user-bundle": "^2.2",

Did someone have a solution for this?

Thanks for help!

Answer 1

I finally start from a new project and use the https://github.com/sonata-project/sandbox as base (My project will use some other sonata projects)

So, probably a misconfiguration...
