gherkin 2.4.0 breaks cuke4duke 0.4.3/0.4.4 running using maven

[krisb]

I am using cuke4duke using maven and java steps. I've installed it using the bootstrapping instructions.

Because of the way the dependencies are declared using ">=", when you install cuke4duke you get cucumber >= 0.10.2 and gherkin >= 2.3.5. Really these should be ~> I think.

The problem is that there is a backward incompatible change in gherkin 2.4.0 so the following error is given:

uninitialized constant Gherkin::Formatter::Model::PyString

This can be fixed quickly by adding a runtime dependency before the cucumber one to gherkin ~> 2.3.5 so that it gets resolved to 2.3.x prior to it trying to use cucumber 0.10.3 and gherkin 2.4.0, forcing the correct gem resolution.

I had the same problem.
I did not find out where to change those dependencies.
So I am staying on my running environment which uses cuke4duke 0.3.2.

@jbandi,
In the gemspec for cuke4duke add the following line

s.add_runtime_dependency(%q, ["~> 2.3.5"])

before any dependencies on cucumber. The gemspec files should be in %PATH_TO_JRUBY%\lib\ruby\gems\x.x\specifications
You should now be able to run cuke4duke 0.4.4 from jruby now.
