Heroku push rejected, no Cedar-supported app detected about heroku-buildpack-ruby-jekyll HOT 8 CLOSED

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'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?

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.

from heroku-buildpack-ruby-jekyll.

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...

from heroku-buildpack-ruby-jekyll.

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

Thanks.

from heroku-buildpack-ruby-jekyll.

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
 !

 !     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.

from heroku-buildpack-ruby-jekyll.

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:

and another error after specified ruby as 2.0.0:

No idea how to fix this. Please help.

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.
