Can't publish package assets

[ghost]

• Laravel Version: 5.4.28
• PHP Version: 7.1.5
• Composer Version: 1.4.1
• Horizon Version: 0.1.0

Description:
Can't publish the package assets or the "horizon.php" config file.

Steps To Reproduce:
composer require laravel/horizon
Then:
php artisan vendor:publish

Result

1. Composer actually installs the package in the vendor folder and adds it in the 'composer.json' file.
2. The vendor publish only publishes the Laravel framework assets (Notification, Pagination, Mails) but not the horizon assets.

Horizon requires Laravel 5.5

Yep, look at README

Horizon requires Laravel 5.5, which is currently in beta, and PHP 7.1+. You may use Composer to install Horizon into your Laravel project

Add Laravel\Horizon\HorizonServiceProvider::class in providers.

Sorry, the problem was that I didn't added the Laravel\Horizon\HorizonServiceProvider::class to providers.
