Question

I am trying to deploy a project to Heroku.

The project has previously been successfully deployed, but now I get the following output when deploying:

   [...]
   Using rspec-expectations (2.8.0)
   Using rspec-mocks (2.8.0)
   Using rspec (2.8.0)
   Using bundler (1.1.rc.7)
   Your bundle is complete! It was installed into ./vendor/bundle
   Cleaning up the bundler cache.

 !     Heroku push rejected, failed to compile Ruby app

We have pinpointed the line in Gemfile that causes this to be:

gem 'internal-lib', :git => 'https://username:[e-mail]/Projectname/internal-lib'

When bundler installs the gem it looks alright:

   Fetching https://username:[e-mail]/Projectname/internal-lib

In what ways can a successfully bundled gem cause the “Cleaning up the bundler cache” step to timeout?

We have tried to include the gem in other ways, as a raw copy of the repo in vendor/private and as a git submodule in vendor/private but no success.

It seems like it was a problem with Heroku. Today the deploy worked again, without changes from our side…
