Update Plugin To Sw67

Example Before:

/**
 * @Route(defaults={"_routeScope"={"storefront"}})
 */
class MyAjaxController extends StorefrontController {
    /**
     * @Route("/my-route", name="frontend.my.route", methods={"GET"})
     */
    public function myAction() {}
}

Example After:

#[Route(defaults: ['_routeScope' => ['storefront']])]
class MyAjaxController extends StorefrontController {
    #[Route(path: '/my-route', name: 'frontend.my.route', methods: ['GET'])]
    public function myAction() {}
}

2. Replacing Removed Interfaces

Certain interfaces heavily used in previous Shopware versions have been deprecated and removed.

Action Required:

• EntityRepositoryInterface: Replace use Shopware\Core\Framework\DataAbstractionLayer\EntityRepositoryInterface; with the concrete class use Shopware\Core\Framework\DataAbstractionLayer\EntityRepository;.

Example: Change private EntityRepositoryInterface $repository; to private EntityRepository $repository;.

3. Modernizing Dependency Injection (Constructor Property Promotion)

To adhere to modern PHP 8 standards and typical Shopware repository guidelines (like AGENTS.md), dependency injection should be refactored to use constructor property promotion.

Action Required:

• Refactor all __construct methods in controllers, services, and subscribers.
• Use private readonly for injected dependencies.

Example Before:

class MyService {
    private EntityRepository $repo;
    
    public function __construct(EntityRepository $repo) {
        $this->repo = $repo;
    }
}

Example After:

class MyService {
    public function __construct(
        private readonly EntityRepository $repo
    ) {}
}

5. Fetch Latest Upgrade Documentation

The skill includes a script to fetch the latest Shopware upgrade guides directly from the official repository.

Action Required:

• Run the fetch script to get the most current upgrade documentation:

./fetch-upgrade-docs.sh

This will download the latest versions of:

• UPGRADE-6.5.md
• UPGRADE-6.6.md
• UPGRADE-6.7.md

The documents are saved in the resources/ folder with timestamps and source URLs for reference.

6. composer.json Updates

Ensure the plugin requires the correct Shopware core version.

Action Required:

• Update composer.json to require "shopware/core": "6.7.*".

7. Clean Up Codebase

• Run phpstan and php-cs-fixer if available in the project to verify type safety and formatting.
• Ensure no backward compatibility code remains if the user specifies no backward compatibility is needed.

Follow these steps meticulously to ensure the upgraded plugin performs seamlessly in Shopware 6.7 environments.
