doctrineHelper.php throws an error when executing the make:entity symfony command

Question

I'm trying to create an entity user using the command line php bin/console make:entity

But it keeps giving me this error:

In DoctrineHelper.php line 187:

  Cannot access protected property Doctrine\ORM\Mapping\Driver\AnnotationDriver::$classNames


make:entity [-a|--api-resource] [-b|--broadcast] [--regenerate] [--overwrite] [--] [<name>]

I downloaded all the requirements according to the official website instructions https://symfony.com/doc/5.4/doctrine.html

This issue is triggered by the newly released Doctrine ORM 2.12.0

Until Symfony or Doctrine push a fix (and there hasn't been time to check which package is "problematic"), you can downgrade to Doctrine ORM 2.11.3.

Change the following lines in your composer.json:

"doctrine/orm": "^2.12",

to:

"doctrine/orm": "^2.11",

And modify your conflict section so that 2.12 will not be installed:

"conflict": {
      "symfony/symfony": "*",
      "doctrine/orm": "2.12.0"
    },

Afterwards, run composer updatedoctrine/orm to downgrade the package and bin/console make:entity should work again.

I discovered that the issue had been reported to symfony/maker-bundle a few days ago. Monitoring this issue is a good way to know when you can upgrade your Maker bundle and remove doctrine/orm conflicting declarations from your configuration.
