Support multiple regexes for java ParameterType annotation

[bartsopers]

🤔 What's the problem you're trying to solve?

I have a custom parameter type that resembles the built-in "string" parameter type. I want to allow enclosing the parameter in either single or double quotes. In the built-in "string" parameter type, this is achieved by using 2 regexes for the parameter type: one for eclosing it in single quotes and one for enclosing it in double quotes. However, the io.cucumber.java.ParameterType annotation only allows a single regex, although the io.cucumber.cucumberexpressions.ParameterType class does support multiple regexes.

✨ What's your proposed solution?

Change the return type of io.cucumber.java.ParameterType#value to String[] instead of String to allow multiple regexes to be provided to io.cucumber.cucumberexpressions.ParameterType

Sounds reasonable.

It would strictly speaking be a breaking change, but I don't think anyone but Cucumber processes these annotations.

Would you be interested in sending a pull request?

I tried, but I ran into some unexpected behavior where all capturing groups of all supplied regexes are passed as arguments to the @ParamaterType annotated method, whereas I would expect that only the capturing groups of the first matching regex would be passed as arguments. Idk whether this is intended behavior, but unfortunately I don't have enough time to diver deeper into it.

For now I worked around my issue by combining the two regexes into one.

That is the expected behavior. See for example the {string} parameter type:
