Can you share your Gemfile? If you using a :git => for warbler be aware that bundler will not work with shallow repos.

I used the following Gemfile to get latest warbler because the released gem had issues that I don't remember any more:

source 'https://rubygems.org'

gem 'google_drive'
gem 'launchy'
gem 'mail'
gem 'warbler', github: 'jruby/warbler'

Are you saying that warbler creates shallow repos and bundler can't handle them? I am just following the README that says: "Warbler supports Bundler for gems and git repositories, but not for plain path components."

No, it should handle git gems. The only reason I brought it up was that I got the same error on the CI server because it was pointing to a repo that was checked out with the --depth=50 option. I believe the error you are seeing is generated by Bundler (as opposed to Warbler) -- I'm not saying it's bundler's fault, though. I'll have to look into it some more.
