This is a Heroku buildpack for vendoring binaries into your project. It doesn't do anything else, so to actually compile your app you should use heroku-buildpack-multi to combine it with a real buildpack.
$ ls .vendor_urls .buildpacks $ heroku create --stack cedar --buildpack http://github.com/dollar/heroku-buildpack-multi.git $ git push heroku master ... -----> Heroku receiving push -----> Fetching custom buildpack -----> Found a .vendor_urls file Vendoring https://s3.amazonaws.com/my-bucket/foo.tar.gz ...
The buildpack will detect that your app has a
.vendor_urls file in the root. Each line in this file will be treated as a URL pointing at a tarball to fetch and extract into your application's root directory.
Copy the snippet above into CLI.
