Hi Varun, It looks like you're getting a null pointer exception which isn't surprising to me at all because you're not initialising the `bindingUpdater` variable anywhere and you are attempting to access a property of it.
To be honest, I've never really used Cucumber for anything meaningful. All of the experience I have with it is keeping the project at https://github.com/geb/geb-example-cucumber-jvm, which was contributed by a community member, working as I release new versions of Geb. I can see that you are using what looks like a "hooks class" to me as opposed to using a script at src/cucumber/resources/env/env.groovy like in the example but I don't know which one is more "correct" for a cucumber project that is being bootstrapped at this point in time. I think this is a question which can probably only be answered by somebody with more knowledge about using Cucumber especially with Groovy.
