There's two copies of 'jruby stldib' and 'jruby core' each. I suspect we only need the one?

The impact is that the resulting kibana.jar is probably ~10-20MB larger than required.

The solution to this is to remove the "warbler" dependency from the Gemfile (src/server/Gemfile)

[simianhacker]

I will probably add a second Gemfile in the root of the project to ensure that the proper dependencies are included for building the project vs the deployment dependencies.

[jordansissel]

You don't need a separate gemfile - you can use groups inside the Gemfile, check out: http://bundler.io/v1.6/groups.html

Example:

group :build do
  gem "warbler"
end

This allows you to do 'bundle install --with build' to get normal + build dependencies, but the normal deps won't include warbler.
