Serenity with Cucumber and Groovy step definitions

[themathmagician]

Hello,
I have searched in vain for an example of Serenity with Cucumber and Groovy step definitions.
I have tried to adapt the closest thing, that is cucumber-webtests
I have added a gradle.build file (see pull request), and things work fine with step definitions in Java.
However, with Groovy step definitions, it seem like the PageObjects are not injected properly.
I wonder if you can point me to any example, or tell what might be wrong?
Here is the
question I have asked on Stack Overflow
