Yard fails with undefined method `new' for nil:NilClass

[aslakhellesoy]

To reproduce:

git clone git://github.com/cucumber/cucumber-rails.git
cd cucumber-rails
bundle install
rake yard

This has worked previously - not sure when it broke. Happens on both 0.7.2 and 0.7.3

[aslakhellesoy]

Weird. If I change Rakefile to do require 'bundler' instead of require 'bundler/setup' it works. I suppose some monkey-patching gems are stompin on each other...

[aslakhellesoy]

If I put require 'bundler/setup' back I get:

rake yard -t
** Invoke yard (first_time)

Tasks: TOP => yard

[aslakhellesoy]

FWIW, bundle exec rake yard also fails

[lsegal]

bundle exec yard works, however, at least for me. I assume there is something in require 'bundler/setup' that is breaking the way YARD loads rdoc. I will verify whether this is YARD's fault or not

[lsegal]

Closed by the above commit. Should solve this issue. A temporary workaround would be to require 'rdoc' in your Rakefile after bundler/setup

[cmeiklejohn]

I'm experiencing this regardless if I have require 'bundler' or require 'bundler/setup'

[cmeiklejohn]

Ah, inside of my gemspec I needed to explicitly require rdiscount as a dependency, which resolved the problem.
