heroku build package

[Ryan Desfosses]

Hello,

Has any one used heroku's build package to post a happstack application to heroku?

I tried using the haskell-buildpack-demo on github with happstacks hello world, but I keep getting "no Cedar-supported app detected."

$ git push heroku master
-----> Fetching custom git buildpack... done
 !     Heroku push rejected, no Cedar-supported app detected

To g...@heroku.com:still-earth-6623.git
 ! [remote rejected] master -> master (pre-receive hook declined)
error: failed to push some refs to 'g...@heroku.com:still-earth-6623.git'

$ heroku logs
...
Slug compilation failed: no Cedar-supported

The repo that I'm trying to push is https://github.com/rdesfo/haskell-buildpack-demo.

Thanks,
Ryan
