Uhh... Is this how other people are dealing with private dependencies?

deploy.rake

namespace :deploy do
  desc 'Deploy the app to Heroku'
  task :heroku do
    inform         = lambda { |message| puts "\e[37;44m#{message}\e[0m" }
    deploy_branch  = 'deploy'
    current_branch = %x"git rev-parse --abbrev-ref HEAD".chomp

    if current_branch == deploy_branch
      inform.call "You're in the #{deploy_branch} branch, which we need to reset, please go elsewhere ;)"
      exit 1
    end

    inform.call "Pulling Heroku's master branch into a local #{deploy_branch} branch"
    sh "git branch -D #{deploy_branch}"
    sh "git fetch heroku master:#{deploy_branch}"
    sh "git checkout #{deploy_branch}"

    inform.call "Merging master in the #{deploy_branch} branch"
    sh "git merge master"

    inform.call "Vendoring all our dependencies (we do this b/c some are stored in private github repos)"
    sh "bundle package --all"


    system "git diff --cached --exit-code"
    if !$?.success?
      inform.call "Committing the vendored changes"
      sh "git add --all"
      sh "git commit -m 'Vendor dependencies'"
    else
      inform.call "No changes to vendored dependencies"
    end

    inform.call "Run tests to make sure everything still works"
    sh "env RAILS_ENV=test   bundle exec   rake db:drop db:create db:migrate db:seed" # reset test db
    sh "bundle exec rake test:all"

    inform.call "Pushing #{deploy_branch} branch to Heroku's master branch"
    sh "git push heroku #{deploy_branch}:master"

    inform.call "Running any migrations"
    sh "heroku run rake db:migrate"

    inform.call "Sending you to your previous branch"
    sh "git checkout -"

    inform.call "Opening the site so you can make sure its up and everything looks right"
    sh "open http://enroll.turing.io"
  end
end
