Jruby on Rails not deploying to Heroku? - ruby-on-rails

Question

I've spent hours unsuccessfully trying to deploy my app to Heroku, and can't figure out the problem. I'm running on Windows and using JDK8 Jruby9.0.0.0. I set up using the instructions found here and deploy a new app using this tutorial. The exact commands I'm using are:
C:\Users\MyName>Jruby -S rails new MyApp
---
C:\Users\MyName>cd MyApp
---
C:\Users\MyName\MyApp>git init
---
C:\Users\MyName\MyApp>git add .
---
C:\Users\MyName\MyApp>git commit -m "my first commit"
---
C:\Users\MyName\MyApp>heroku create
---
C:\Users\MyName\MyApp>git push heroku master
---
C:\Users\MyName\MyApp>heroku open
Unfortunately this provides the following "Applicaton Error" when I try to open the app:

I've followed instructions found on SO which suggest renaming bin/bundle,rails,rake to remove the '.exe', but this does not work.
Any ideas on what is going wrong here? Thanks!
EDIT:
I should have said that the app cloned in the Heroku tutorial deploys to Heroku as it should, but unfortunately it is completely different in structure to the app created by the CMD command 'Jruby -S rails new MyApp'. The cloned app has no 'bin' directory, and the 'Jruby -S new' app has no procfile. I think this means that the problem lies with how the 'Jruby -S new' app is configured to deploy, i.e. I need to specify how the process should start? Both apps work locally.
I know I could clone the heroku app every time I create a new rails app, but this seems like a bit of a clunky work around!

It looks like you may have your bin/rails script checked into Git. And if that script was generated on Windows, I think it will have jruby.exe in it. Make sure you remove those files by running:
> git rm -rf bin
And then add bin/ to your `.gitignore to make sure it doesn't get back in. Then finally:
> git commit -am "remove bin scripts"
> git push heroku master
