Adding new form and entities to Symfony does not work - php

Question

I've forked a Symfony 3 project and I'm trying to add a new Entity and the matching form type, but I can't make it work.
I've tried with the generator and manually, both won't work. A solution with the generator would be the best option
I've generated my entity School with php bin/console doctrine:generate:entity, but when I'm trying to generate the Form, I get the error Class GreenBundle\Entity\School does not exist.
I then tried to create the Form manually and got : Expected to find class "GreenBundle\Form\SchoolType" in file "/var/www/symfony/src/GreenBundle/Form/SchoolType.php" while importing services from resource "../../src/GreenBundle/*", but it was not found! Check the namespace prefix used with the resource.
My school entity generated by the command line is simple
<?php
namespace GreenBundle\Entity;
use Doctrine\ORM\Mapping as ORM;
/**
* School
*
* #ORM\Table(name="school")
* #ORM\Entity(repositoryClass="GreenBundle\Repository\SchoolRepository")
*/
class School
{
/**
* #var int
*
* #ORM\Column(name="id", type="integer")
* #ORM\Id
* #ORM\GeneratedValue(strategy="AUTO")
*/
private $id;
/**
* #var string
*
* #ORM\Column(name="nom", type="string", length=255)
*/
private $nom;
(... Some other variables, the getters and setters )
}
The SchoolType I added is :
<?php
namespace GreenBundle\Form;
use Symfony\Component\Form\AbstractType;
use Symfony\Component\Form\FormBuilderInterface;
use Symfony\Component\Form\Extension\Core\Type\EmailType;
use Symfony\Component\Form\Extension\Core\Type\RepeatedType;
use Symfony\Component\Form\Extension\Core\Type\PasswordType;
use Symfony\Component\Form\Extension\Core\Type\TextType;
use Symfony\Component\OptionsResolver\OptionsResolver;
class SchoolType extends AbstractType
{
/**
* #param OptionsResolver $resolver
*/
public function configureOptions(OptionsResolver $resolver)
{
$resolver->setDefaults(array(
'data_class' => 'GreenBundle\Entity\School',
));
}
/**
* #return string
*/
public function getName()
{
return 'green_mainbundle_school';
}
/**
* #param FormBuilderInterface $builder
* #param array $options
*/
public function buildForm(FormBuilderInterface $builder, array $options)
{
$builder->add('nom', TextType::class, array(
'label' => "Nom de l'école",
'required' => false,
'attr' => array(
'class' => 'form-control',
'placeholder' => 'ex: École Saint-Exupéry')
));
}
}
And the block In services.yml the error code is referring to is :
# this creates a service per class whose id is the fully-qualified class name
GreenBundle\:
resource: '../../src/GreenBundle/*'
# you can exclude directories or files
# but if a service is unused, it's removed anyway
exclude: '../../src/GreenBundle/{Entity,Repository,Tests}'
Do you know what I'm doing wrong to get the server to run with the new SchoolType and be able to use it in a controller ?
Thanks
======== Edit
I do have Symfony 3
php bin/console --version
Symfony 3.4.14 (kernel: app, env: dev, debug: true)
The project architecture is classic I guess, I have the default folders of Symfony
In the src folder I have :
AppBundle (unused)
GreenBundle
Controller
DataFixtures
DBAL
DependencyInjection
Entity
Form
Repository (Empty, I don't think they created entities with the generator)
Service
Tests
Twig
GreenBundle.php
======== Edit 2
The namespace I use in GreenBundle.php is GreenBundle, you can see the file below
namespace GreenBundle;
use Symfony\Component\HttpKernel\Bundle\Bundle;
class GreenBundle extends Bundle
{
public function getParent()
{
return 'FOSUserBundle';
}
}

In case anybody ever have the same kind of issue, I was running my project in a Docker container and it was a synch problem. The Symfony file themselves are correct. Docker detected that new file were added but didn't set the content properly. Rebuild and/or changing the way I use docker with this app fixes the issue
