Heroku push rejected, no Cedar-supported app detected

[ghiculescu]

I'm seeing this output when I try to push to Heroku today. (I wasn't getting this problem last time I pushed, about three days ago.)

 !     Heroku push rejected, no Cedar-supported app detected

My heroku:config includes this line:

BUILDPACK_URL: http://github.com/mattmanning/heroku-buildpack-ruby-jekyll.git

If I remove that (heroku config:remove BUILDPACK_URL), I can push with no issues. So I suspect it's something to do with the changes made in the last few days - though looking over them, I'm not sure what it could be. Any ideas?

Sorry about that. I merged in some changes from the upstream Ruby
buildpack. It must not be detecting your app as a Ruby app any more for
some reason. Would you mind sharing your Gemfile?

I just undid the most recent changes on the buildpack. Can you try your deploy again?

Sorry for the problems. I'll do more testing next time.

[ghiculescu]

No worries. Thanks for your prompt help, I really appreciate it :)

That seems to have fixed it. Do you think I should report it to the Heroku guys? I don't know very much about buildpacks so I'm not sure what went wrong :/

For the record, I'm trying to deploy this repo: https://github.com/ghiculescu/payaus-docs
So if you do want to test it yourself you're welcome to. I probably should have mentioned that from the start...

[krstffr]

I get the same error. Did you guys find a solution?

Thanks.

[ssaunier]

I had the same error, then I added a Gemfile:

source 'https://rubygems.org'
ruby '2.1.2'

gem 'redcarpet'
gem 'jekyll'

Now when I git push heroku master I get:

-----> Fetching custom git buildpack... done
-----> Ruby app detected
 !
 !     Invalid RUBY_VERSION specified: ruby-2.1.2
 !     Valid versions: ruby-2.0.0, ruby-1.9.3, ruby-1.9.2, ruby-1.8.7, ruby-1.9.3-jruby-1.7.0, ruby-1.8.7-jruby-1.7.0, ruby-1.9.3-jruby-1.7.1, ruby-1.8.7-jruby-1.7.1, ruby-1.9.3-rbx-2.0.0dev, ruby-1.8.7-rbx-2.0.0dev
 !

 !     Push rejected, failed to compile Ruby app

I don't know where to look in the code, but I would be happy to help fix this issue.

[mytharcher]

Same with you @ssaunier . If any ruby version specified in Gemfile not match to Heroku provided ones, this would happen.

I got another error because the ruby version not specified:

remote:        An error occurred while installing classifier-reborn (2.0.2), and Bundler cannot

and another error after specified ruby as 2.0.0:

remote:        env: bundle: No such file or directory
remote:  !

 ! [remote rejected] master -> master (pre-receive hook declined)

No idea how to fix this. Please help.

[mattmanning]

Any repo with a Gemfile.lock should get detected as a ruby app by Heroku.

I have updated the buildpack with the latest upstream Heroku Ruby buildpack and the current jekyll subcommands. I'm closing this issue, but please feel free to open a new one if you have further problems.
