PHP / Laravel build doesn't work on Heroku, artisan command is missing PHP class

I have an app configured with Heroku with setup Procfile

and composer.lock

removed from .gitignore

. The app is a Laravel 4.2 installation with a custom artisan command that emails every email every Friday; it is very simple and nothing complicated.

The command is in app/commands

, and the (sendEmail) class is registered in app/start/artisan.php

. I don't know if I need to combine with composer.json to autoload the class, but I feel like it's already included since any classes in are app/

already loaded automatically.

Here's what happens after I click on Heroku:

vagrant@homestead:~/Code/email-schedule/email-schedule$ git push heroku master

I have tried different things, such as artisan optimize

, composer dump-autoload

, artisan clear-compiled

, and nothing works. It looks like Artisan was caching my own command class somewhere and Heroku is trying to access it, but I'm not entirely sure. How do I fix the missing class error?
