When using own service in /config/app.php:

'providers' => array_merge(include(base_path().'/modules/system/providers.php'), [
    'System\ServiceProvider',
    'Jenssegers\Agent\AgentServiceProvider',
]),

...and fire project update at Backend, it fails with:

And than whole application crash:

Mon Nov  2 11:40:56 2015] PHP Fatal error:  Class 'Jenssegers\Agent\AgentServiceProvider' not found in /Users/VojtaSvoboda/Www/mysite.com/vendor/laravel/framework/src/Illuminate/Foundation/ProviderRepository.php on line 150

Tested on Jenssegers\Agent and Intervention\Image and same problem. It fails only when updating system, no when updating plugins. After crash - only what helps is composer update.

Anyone with same problem or some solution? One way is encapsulate 3th party services to special plugin, but i think it should works independently.

Try loading/adding the service provider in your actual plugin itself so it's all contained within the plugin rather than in your app.php - in your plugin boot() method you can use

App::register('Jenssegers\Agent\AgentServiceProvider');

then you can use use Jenssegers\Agent\Agent; in your plugin.

Where is your composer.json file, within your plugin directory or elsewhere?

If you use composer it is a good idea to disable core updates and update using composer instead. You should still receive plugins updates.

See config/cms.php

Thank you guys, both solutions are working well!

I'm getting this error while my serviceprovider IS loaded in my plugin... Everything works just fine locally but when pushing to production I get :

Class 'Vinkla\Hashids\HashidsServiceProvider' not found ../vendor/laravel/framework/src/Illuminate/Foundation/Application.php line 575

Ok I fixed it... HashidsServiceProvider 3.1 doesn't support laravel 5.1 :) downgraded to 2.4...

My bad :)

now it works but artisan is messed up... When I try to refresh a plugin I get [Symfony\Component\Debug\Exception\FatalThrowableError] Class 'Vinkla\Hashids\HashidsServiceProvider' not found
