In ProviderRepository.php line 208: Class 'Sentry\SentryLaravel\SentryLaravelServiceProvider' not found

I'm trying to install Sentry Error Tracking into my Laravel 5 Project. It throws an Error when i try publishing the Provider using the command

php artisan vendor:publish --provider="Sentry\SentryLaravel\SentryLaravelServiceProvider"

I added this into config/app.php

'providers' => array(
    // ...
    Sentry\SentryLaravel\SentryLaravelServiceProvider::class,
)

'aliases' => array(
    // ...
    'Sentry' => Sentry\SentryLaravel\SentryFacade::class,
)

Then i ran

php artisan vendor:publish --provider="Sentry\SentryLaravel\SentryLaravelServiceProvider"

And it threw the Error

In ProviderRepository.php line 208:
Class 'Sentry\SentryLaravel\SentryLaravelServiceProvider' not found

I've been searching for various solutions but none of them worked for me. This is very important for my project. Can i please please get some assistance. Thank You.
