Heroku Slug size too large.

heoku_large_slug.md

Purging the cache fixed it.

Install the Heroku Repo plugin:

https://github.com/heroku/heroku-repo

Then run:

heroku repo:gc --app your-app-name
heroku repo:purge_cache --app your-app-name

These commands will execute git gc --agressive (git-clean) and delete the contents of the Heroku build cache stored in your application’s Git repository.

Doing this on a recent app reduced my slug size by 100M.
