Bundle Class

<?php
namespace Acme\Bundle\DemoBundle;

use Symfony\Component\HttpKernel\Bundle\Bundle;

class AcmeDemoBundle extends Bundle
{
    public function getPath(): string
    {
        return __DIR__;
    }
}

The getPath() method in v6.1 replaces legacy container-relative path logic, enabling the kernel to locate bundle resources automatically.

DependencyInjection Extension

<?php
namespace Acme\Bundle\DemoBundle\DependencyInjection;

use Symfony\Component\Config\FileLocator;
use Symfony\Component\DependencyInjection\ContainerBuilder;
use Symfony\Component\DependencyInjection\Extension\Extension;
use Symfony\Component\DependencyInjection\Loader;

class AcmeDemoExtension extends Extension
{
    #[\Override]
    public function load(array $configs, ContainerBuilder $container): void
    {
        $loader = new Loader\YamlFileLoader(
            $container,
            new FileLocator(__DIR__ . '/../Resources/config')
        );
        $loader->load('services.yml');
    }

    #[\Override]
    public function getAlias(): string
    {
        return 'acme_demo';
    }
}

Use #[\Override] attributes (standard in v6.1) — they catch method signature mismatches at compile time.

Bundle Registration

Register in Resources/config/oro/bundles.yml:

bundles:
  - { name: Acme\Bundle\DemoBundle\AcmeDemoBundle }

Priority: Lower loads first. Omit priority (defaults to 0) for custom bundles unless you need to override config from a specific Oro bundle.

Service Configuration

services:
  acme_demo.my_service:
    class: Acme\Bundle\DemoBundle\Service\MyService
    public: false

  acme_demo.event_listener.my_listener:
    class: Acme\Bundle\DemoBundle\EventListener\MyListener
    tags:
      - { name: kernel.event_listener, event: kernel.request, method: onRequest }
    arguments:
      - '@logger'

Tags trigger compiler passes that register listeners, commands, and API endpoints. Verify with debug:container acme_demo.

See bundle-patterns.md for service decoration, compiler passes, event listeners, navigation menus, system configuration, and translations.

Post-Installation Commands

php bin/console cache:clear
php bin/console debug:container acme_demo  # Verify services registered

Cache clear is critical — changes to bundles.yml, services.yml, or navigation.yml take effect only after clearing.

Key Pitfalls

1. Missing cache clear: Bundle config changes (services, navigation, system config) are invisible until cache:clear runs. This is the most common "it doesn't work" cause.
2. Wrong extension alias: The DI extension alias must match the bundle name convention (acme_demo for AcmeDemoBundle). A mismatch silently skips your services.yml loading.
3. Priority ordering confusion: In bundles.yml, lower priority loads first (opposite of processor priority). Most custom bundles should omit priority entirely.
