Unable to create entity named “Attribute” using maker bundle

[ilbee]

Description

It is not possible to create an entity named “Attribute” using the maker bundle.

A message indicating that the entity exists appears when running the make:entity command.
Followed by an error:

In FileManager.php line 111:
Warning: file_get_contents(/project/path/): Failed to open stream: No such file or directory

How to reproduce

1. Create a Symfony project (version 6.4 and above):

   symfony new test_project --version=6.4
   cd ./test_project/

2. Install the ORM pack and the maker bundle:

   symfony composer require symfony/orm-pack symfony/maker-bundle

3. Attempt to create the "Attribute" entity:

   symfony console make:entity Attribute

The console will return an output like this:

Your entity already exists! So let's add some new fields!

In FileManager.php line 111:

Warning: file_get_contents(/project/path/): Failed to open stream: No such file or directory

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

Possible Solution

The issue seems to come from line 191 of the Generator class in the maker bundle:

<?php
// ./maker-bundle/src/Generator.php
[...]
public function createClassNameDetails(string $name, string $namespacePrefix, string $suffix = '', string $validationErrorMessage = ''): ClassNameDetails
    {
        (...)
        Validator::classDoesNotExist($className);
        (...)
    } 
[...]

This check verifies if the entered class already exists, but not using namespacePrefix value.
However, since PHP 8, the Attribute class exists for managing class attributes (vs annotations).

<?php
namespace Example;

use Attribute;
#[Attribute(Attribute::TARGET_METHOD)]
class MyAttribute
{
}

The check should be modified to verify that the class exists in the namespace.
What do you think?

Additional Context

Here is the output of the make:entity command in verbose mode.

symfony console make:entity Attribute -vvv
