Steps to create:

symfony new --version=lts mapping-driver-bug-demo

symfony composer require orm
symfony composer require symfony/maker-bundle --dev
echo 8 > ./.php-version

Add type: attribute to doctrine.orm.mappings.App

Create a separate temp-vendors structure to emulate a Bundle in vendors using annotations

Add PSR mapping for ABCBundle in composer.json

symfony composer dump-auto

Add ABCBundle to bundles.php

To replicate:

symfony console make:entity FailedEntity

Expect: Entity to be created without error and with attributes

Actual

• Entity created with error 'Only annotation or attribute mapping is supported by make:entity'
• Entity created with annotations

To confirm normal behavior:

Comment out ABCBundle in bundles.php

New entities are now created without error and with attributes
