Hello!

I just started Shopware6 with dockware and I follow the video guides.

I am at the video where I created the entity’s files and now in the container I have to create the migration.

When I issue the command „bin/console make-migration -p SwagShopFinder“ I get the following error

```auto
www-data@5914cb6f68b7:~/html$ bin/console database:create-migration -p SwagShopFinder
Symfony\Component\ErrorHandler\Error\ClassNotFoundError^ {#9687
  #message: """
    Attempted to load class "ShopFinderDefinition" from namespace "SwagShopFinder\Core\Content\ShopFinder".\n
    Did you forget a "use" statement for another namespace?
    """
  #code: 0
  #file: "./vendor/shopware/core/Framework/DependencyInjection/CompilerPass/EntityCompilerPass.php"
  #line: 50
  trace: {
    ./vendor/shopware/core/Framework/DependencyInjection/CompilerPass/EntityCompilerPass.php:50 { …}
    ./vendor/shopware/core/Framework/DependencyInjection/CompilerPass/EntityCompilerPass.php:25 { …}
    ./vendor/symfony/dependency-injection/Compiler/Compiler.php:82 { …}

    ./vendor/symfony/http-kernel/Kernel.php:546 { …}
    ./vendor/shopware/core/Kernel.php:189 { …}
    ./bin/console:74 {
      › $application = new Application($kernel->getKernel());
      › $kernel->getKernel()->boot();
      › $application->setName('Shopware');
    }
  }
}

```

One thing I have in mind is that the newly created files comes with the following uses:

```auto
use Shopware\Core\Framework\DataAbstractionLayer\EntityCollection; 

```

for ShopFinderCollection.php

```auto
use Shopware\Core\Framework\DataAbstractionLayer\EntityDefinition;
use Shopware\Core\Framework\DataAbstractionLayer\Field\FkField;
use Shopware\Core\Framework\DataAbstractionLayer\Field\LongTextField;
use Shopware\Core\Framework\DataAbstractionLayer\Field\ManyToOneAssociationField;
use Shopware\Core\Framework\DataAbstractionLayer\FieldCollection;
use Shopware\Core\Framework\DataAbstractionLayer\Field\BoolField;
use Shopware\Core\Framework\DataAbstractionLayer\Field\Flag\PrimaryKey;
use Shopware\Core\Framework\DataAbstractionLayer\Field\Flag\Required;
use Shopware\Core\Framework\DataAbstractionLayer\Field\IdField;
use Shopware\Core\Framework\DataAbstractionLayer\Field\StringField;
use Shopware\Core\System\Country\CountryDefinition;

```

for ShopFinderDefinition.php

and

```auto
use Shopware\Core\Framework\DataAbstractionLayer\Entity;
use Shopware\Core\Framework\DataAbstractionLayer\EntityIdTrait;
use Shopware\Core\System\Country\CountryEntity;

```

for ShopFinderEntity.php

while the folders Shopware\Core\Framework\DataAbstractionLayer\EntityCollection are in the vendor folder not in the project folder.

I do not know if I have a correct guess but I just need a helping hand with this.

Thanks in advance!

It seams that one of the files were not uploaded since I use SFTP with the container. After a refresh everything was ok.

Ty!
