Timestampable in new Symfony 7 Project throws error on migration

[GBeushausen]

Hi,

i'm trying to add TimeStampableEntity trait to the user Entity in a new Symfony 7 project. After adding the trait i want to create a migration. But it fails with this message:

[Semantical Error] The class "Doctrine\ORM\Mapping\Column" 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\Column". If it is indeed no annotation, then you need to add @IgnoreAnnotation("ORM\Column") to the _class_ doc comment of property App\Entity\User::$createdAt.

What can i do to make it work?

I found out that this project is not compatible with Doctrine 3. Would be great to mention this somewhere.

The trait does not come from this bundle.

And both Symfony 7 and Doctrine 3 removed support for annotations. So I'm wondering what is still trying to read annotations.

@stof Thanks. Meanwhile i found out that the underlying doctrine-extensions library is not yet compatible with Doctrine 3.
