Description

Running a command using the standalone Console component throws an error:

PHP Fatal error: Uncaught TypeError: Symfony\Component\Console\Application::add(): Argument #1 ($command) must be of type Symfony\Component\Console\Command\Command, App\MyCommand given, called in /var/www/html/bin/console.php on line 12 and defined in /var/www/html/vendor/symfony/console/Application.php:53

add() expects a Command, but the example doesn't extend anything, since it uses the AsCommand attribute instead.

How to reproduce

1. Install dependencies:

composer require symfony/console

2. Create a basic command, per the documentation:

#[AsCommand(name: 'app:my-command')]
final readonly class MyCommand
{
    public function __invoke(): int
    {
        return Command::SUCCESS;
    }
}

3. Create the console app, per the documentation:

#!/usr/bin/env php
<?php

require __DIR__.'/../vendor/autoload.php';

use App\MyCommand;
use Symfony\Component\Console\Application;

$application = new Application();

$application->add(new MyCommand());

$application->run();

4. Run:

bin/application.php app:my-command
