Running RSpec and Cucumber from C#

You might be wondering why on earth you’d want to do this, but it’s trickier than it looks.  I’ve published a gist for it.  There’s a couple of comments about how to get things set up as well.

The bad news is, RSpec works, but Cucumber doesn’t.  Instead I’m getting this:

can't convert Array into java::util::List (TypeError) 
C:/Program Files/IronRuby 1.0v4/lib/ironruby/gems/1.8/gems/gherkin-2.0.2-universal-dotnet/lib/gherkin/native/ikvm.rb:37:in `new' 
C:/Program Files/IronRuby 1.0v4/lib/ironruby/gems/1.8/gems/cucumber-0.8.3/bin/../lib/cucumber/cli/configuration.rb:29:in `parse!' 
C:/Program Files/IronRuby 1.0v4/lib/ironruby/gems/1.8/gems/cucumber-0.8.3/bin/../lib/cucumber/cli/main.rb:94:in `configuration' 
C:/Program Files/IronRuby 1.0v4/lib/ironruby/gems/1.8/gems/cucumber-0.8.3/bin/../lib/cucumber/cli/main.rb:43:in `execute!' 
C:/Program Files/IronRuby 1.0v4/lib/ironruby/gems/1.8/gems/cucumber-0.8.3/bin/../lib/cucumber/cli/main.rb:25:in `execute' 
C:/Program Files/IronRuby 1.0v4/lib/ironruby/gems/1.8/gems/cucumber-0.8.3/bin/cucumber:8 
C:Program FilesIronRuby 1.0v4bincucumber:19:in `load' 
C:Program FilesIronRuby 1.0v4bincucumber:19 

Yes, you’re reading the first line correctly.  The downside of IKVM, of course, is Java Exceptions that mean nothing to you.  This is quite frustrating for me, because I really wanted to start using Cucumber.  So if anyone’s managed to crack this, drop me a line.  Believe me, I’ve tried enough different versions of the gherkin and cucumber gems to last a lifetime.

On the other hand, I’m rather enjoying RSpec.
