make:entity command: [ERROR] Only annotation mapping is supported by make:entity

Question

When I am trying to create a new doctrine entity in Symfony 5.2 (maker-bundle v1.30.0) I get:

$ php bin/console make:entity

 Class name of the entity to create or update (e.g. GrumpyChef):
 > test

 created: src/Entity/Test.php
 created: src/Repository/TestRepository.php

                                                                                
 [ERROR] Only annotation mapping is supported by make:entity, but the           
         <info>App\Entity\Test</info> class uses a different format. If you     
         would like this command to generate the properties & getter/setter     
         methods, add your mapping configuration, and then re-run this command  
         with the <info>--regenerate</info> flag.

The files are generated and they look OK to me. I get the same for existing entities, except for the "created" lines. I have read about similar problems from years ago, but they were related to different namespaces which is not the case here, I am using the default namespace.

I believe the problem is related to an update, because of course it previously (not sure if it was 5.0 or 5.1) worked.

Is there any way to debug the MakerBundle or any idea how to solve this problem?

Thanks.
