Q	A
BC Break	yes
Version doctrine/orm	3.1
BC Break	no
Version doctrine/orm	2.18

Summary

A semantic error occurs when using the #[Translatable] attribute in an entity.

Previous behavior

All goes well.
No error is displayed.

Current behavior

The following error is displayed:

In AnnotationException.php line 36:

  [Semantical Error] The class "Doctrine\ORM\Mapping\MappedSuperclass" is not annotated with @Annotation.
  Are you sure this class can be used as annotation?
  If so, then you need to add @Annotation to the _class_ doc comment of "Doctrine\ORM\Mapping\MappedSuperclass".
  If it is indeed no annotation, then you need to add @IgnoreAnnotation("ORM\MappedSuperclass") to the _class_ doc comment of class Gedmo\Translatable\Entity\MappedSuperclass\AbstractTranslation.

make:migration [--formatted] [--configuration [CONFIGURATION]]

How to reproduce

After installing stof/doctrine-extensions-bundle

composer require stof/doctrine-extensions-bundle

And made the following changes to the project:

• doctrine.yaml

doctrine:
    dbal:
         ...
    orm:
        ...
    mappings:
       App:
           ...
       gedmo_translatable:
           type: attribute
           prefix: Gedmo\Translatable\Entity
           dir: "%kernel.project_dir%/vendor/gedmo/doctrine-extensions/src/Translatable/Entity"
           alias: GedmoTranslatable # (optional) it will default to the name set for the mapping
           is_bundle: false
    ...

• TheEntity.php

<?php
namespace App\Entity;
...
use Gedmo\Mapping\Annotation\Translatable;
...
class TheEntity
{
    ...
    #[Translatable]
    private string $title = '';
    ...
}

And then makes a:

php bin/console make:migration

The following error is displayed:

In AnnotationException.php line 36:

  [Semantical Error] The class "Doctrine\ORM\Mapping\MappedSuperclass" is not annotated with @Annotation.
  Are you sure this class can be used as annotation?
  If so, then you need to add @Annotation to the _class_ doc comment of "Doctrine\ORM\Mapping\MappedSuperclass".
  If it is indeed no annotation, then you need to add @IgnoreAnnotation("ORM\MappedSuperclass") to the _class_ doc comment of class Gedmo\Translatable\Entity\MappedSuperclass\AbstractTranslation.

make:migration [--formatted] [--configuration [CONFIGURATION]]

This is my first issue.
If I've made any mistakes in this one, I apologize.

This is not a bug with the ORM.

You are trying to use the gedmo/doctrine-extensions package alongside ORM 3.x, and this package is not yet compatible with the new ORM version.
