Composer seems to use vendor config

[nxmndr]

Hello. I only use Calendar and after adapting the config & composer.json files, running composer dumpautoload gives me :

> Google\Task\Composer::cleanup
> Illuminate\Foundation\ComposerScripts::postAutoloadDump
> @php artisan package:discover --ansi

   Error 

  Class "Google\Service\Gmail" not found

  at vendor/tomshaw/google-api/config/config.php:54
     50▕      * Scopes to be requested as part of the OAuth2.0 flow.
     51▕      */
     52▕     'service_scopes' => [
     53▕         Google\Service\Calendar::CALENDAR,
  ➜  54▕         Google\Service\Gmail::GMAIL_SEND,
     55▕         Google\Service\Books::BOOKS,
     56▕         Google\Service\Drive::DRIVE,
     57▕     ],
     58▕ ];

      +9 vendor frames 

  10  artisan:35
      Illuminate\Foundation\Console\Kernel::handle()

Script @php artisan package:discover --ansi handling the post-autoload-dump event returned with error code 1

Cleanup seems to work though and I only have Calendar files.
