cucumber.runtime.CucumberException: Arity mismatch. Declared parameters: [class java.lang.Object]. Matched arguments: []

Hi there,

I'm trying to migrate from cuke4duke to cucumber-jvm.  I'm trying to run the tests via Junit, using groovy step definitions. 

I've got very close, but I get this for most of my steps:

An example step is:

   @357
    Scenario: Carbon Coder executes unsuccessfully
        Given Carbon Coder is running correctly
        ...

And the step definition :

Given(~"Carbon Coder is running correctly\$") {
    transcodeHelper.prepareService()
}

Any ideas for me??

Thanks,
Paul

It works if I add a regex to the step definition.  e.g.

Given(~"Carbon Coder (*.) running correctly\$") { String ignore ->
    transcodeHelper.

    prepareService()
 }

Please register a ticket on github. Not convinced it is a bug, but at
least the error message should be better!
