autoconfigure not tagging commands with symfony dependency-injection - symfony

Question

I have a cli project that I am using Symfony's Dependency Injection and Console components. I am not using a Kernel, controllers, etc.
When using autoconfigure: true, the service doesn't get the console.command tag it is supposed to.
My composer.json:
{
"require": {
"php": "^7.4",
"monolog/monolog": "^2.0",
"symfony/console": "^5.0",
"symfony/dependency-injection": "^5.0",
"symfony/config": "^5.0",
"symfony/yaml": "^5.0"
},
"autoload": {
"psr-4": {"Mudder\\": "src/"}
}
}
./config/services.yaml:
services:
_defaults:
autowire: true
autoconfigure: true
Mudder\:
resource: '../src/*'
exclude: '../src/{DependencyInjection,Entity,Migrations,Tests,Kernel.php}'
public: true
./src/Mudder/Command/HelloWorld.php:
<?php
namespace Mudder\Command;
use Symfony\Component\Console\Command\Command;
use Symfony\Component\Console\Input\InputInterface;
use Symfony\Component\Console\Output\OutputInterface;
class HelloWorld extends Command
{
protected static string $defaultName = 'test';
protected function configure()
{
$this->setDescription('Foo');
}
protected function execute(InputInterface $input, OutputInterface $output)
{
$output->writeln('Hello, world.');
return 0;
}
}
Finally, ./test.php (the cli entrypoint):
<?php
require __DIR__ . '/vendor/autoload.php';
use Symfony\Component\Config\FileLocator;
use Symfony\Component\DependencyInjection\ContainerBuilder;
use Symfony\Component\DependencyInjection\Loader\YamlFileLoader;
$containerBuilder = new ContainerBuilder();
$loader = new YamlFileLoader($containerBuilder, new FileLocator(__DIR__ . '/config'));
$loader->load('services.yaml');
$containerBuilder->compile();
print_r($containerBuilder->getDefinition(\Mudder\Command\HelloWorld::class)->getTags());
Output from the print_r() is an empty array "Array()"

Answer 1

The container itself does know nothing about a Command.
If you want to auto configure your commands, you have to call
$containerBuiler->registerForAutoconfiguration(Command::class)->addTag('console.command');
or load the FrameworkExtension (from symfony FrameworkBundle)

Answer 2

Your command should end with Command. Rename it to HelloWorldCommand.
