Laravel 11, Facing error in Provider is not found in Module

The error you’re encountering mostly occurs when Laravel cannot find the class or file for your module’s service provider due to one of the following issues:

1. Namespace misalignment
   Make sure the namespace in your AdminModuleServiceProvider matches the
   directory structure and the module’s PSR-4 autoload configuration in composer.json.

namespace ModulesAdminModuleProviders;

use IlluminateSupportServiceProvider;

class AdminModuleServiceProvider extends ServiceProvider

{
    
public function register()
    {
        // Register services
    }

    public function boot()
    {
        // Bootstrap services
    }
}

• If your file is located at Modules/AdminModule/Providers/AdminModuleServiceProvider.php, the namespace must match ModulesAdminModuleProviders.
• Composer AutoLoading
• If you created the module manually, ensure your composer.json file includes the module’s namespace in the autoload section:

    "autoload": {
        "psr-4": {
            "Modules\AdminModule\": "Modules/AdminModule/"
        }
    }

• After editing composer.json, run:

    composer dump-autoload

3. Module Discovery

• Verify that the module is registered in the Laravel application’s config/app.php (if applicable) or modules_statuses.json file:

    {
        "Modules\AdminModule\": true
    }

4. Fixing the package:discover Issue

• Run composer dump-autoload again, ensuring no syntax or path errors exist in the project.
• If the issue persists:

  • Check composer.json for post-autoload scripts that might be failing:

     "scripts": {
    "post-autoload-dump": [
        "@php artisan package:discover --ansi"
      ]
    }
    

• Manually run the failing command to see the specific error:

    php artisan package:discover

5. Clearing Laravel Caches

• Laravel may cache the service provider or autoloaded files. Clear the caches to refresh:

    php artisan config:clear
    
    php artisan cache:clear
    
    php artisan route:clear
    
    php artisan clear-compiled
    
    php artisan optimize

Debugging Steps

1. Verify the file path for AdminModuleServiceProvider.php.
2. Ensure the class name and namespace are correctly defined.
3. Check the autoload configuration in composer.json.
4. Run the following commands sequentially:

    composer dump-autoload
    
    php artisan package:discover
    
    php artisan config:clear
