Using a Customized (Forked) Build Pack

This is the default buildpack repository for Grails. You can fork this repo and tell Heroku to use the forked version by passing the --buildpack option to heroku create:

$ heroku create --stack cedar --buildpack [email protected]:bhagwat/heroku-buildpack-predictionio.git

How to use it?

Thank you for creating this buildback, but how do I use it?
Is there an example project I could clone it from?
I tried deploying an empty project with an empty "engine.json" file and I'm getting the following error (after figuring out I had to 'heroku config' the MYSQL connection vars):

remote: [INFO] [Console$] [error] Not a valid command: assemblyPackageDependency
remote: [INFO] [Console$] [error] Not a valid project ID: assemblyPackageDependency
remote: [INFO] [Console$] [error] Expected ':' (if selecting a configuration)
remote: [INFO] [Console$] [error] Not a valid key: assemblyPackageDependency (similar: sbtDependency)
remote: [INFO] [Console$] [error] assemblyPackageDependency
remote: [INFO] [Console$] [error]                          ^

Thank you in advance!
