undefined method `size' for nil:NilClass during resolve

[rsutphin]

In certain circumstances, ivy4r will raise this exception during ivy:resolve:

Buildr aborted!
undefined method size' for nil:NilClass /Users/rsutphin/.rvm/gems/jruby-1.4.0@buildr/gems/ivy4r-0.10.5/lib/buildr/ivy_extension.rb:164:inresolve'
/Users/rsutphin/.rvm/gems/jruby-1.4.0@buildr/gems/ivy4r-0.10.5/lib/buildr/ivy_extension.rb:720:in `after_define'

From inspecting the code in ivy_extension.rb, it appears that this will happen when you have two buildr projects with a parent-child relationship where both of them have ivy.xmls.

The sample app for issue #6 demonstrates this problem if you run ivy:resolve on it.

I've monkey-patched this issue for my situation like so:

class Buildr::Ivy::IvyConfig
  def post_resolve_task_list
    @post_resolve_task_list ||= []
  end
end

However, this just prevents the exception. I think the post-resolve tasks might still be resolved incorrectly (I tried using one yet).
