The new docker-based build environment supports bundler caching on open source projects.
I'm trying to enable it in a pull request but it fails.
I don't know if it can be used when using a build matrix with multiple Gemfiles:
gemfile:
- spec/gemfiles/Gemfile.rails-3.2.x
- spec/gemfiles/Gemfile.rails-4.0.x
- spec/gemfiles/Gemfile.rails-4.1.x
- spec/gemfiles/Gemfile.rails-4.2.x
Has anyone got this working and can share their .travis.yml
?
