Using Annonymous Parameter Types and Jackson Object Mapper for conversion in Cucumber 4.x

Refer to this for more details - https://ghchirp.site/340/

XStream was removed from Cucumber-JVM in version 3 for various reasons. Though it reduced a lot of complexities, it removed functionality which automatically transformed a DataTable into a collection of objects or String to a object. This now requires code for each transformation to define a DataTableType or ParamterType in the TypeRegistry for these cases. This has been made easier in Cucumber-JVM 4.0.0 by using Jackson ObjectMapper for DataTables and Anonymous Parameter Types for Parameters in version 4.2.0. Refer to official announcements for version 4.0.0 and version 4.2.0.

cuke4-parameter-datatable's Issues

The same with lambda expressions

Hi !

Thanks for these usefull samples.

I'm trying to convert the glue to lambda style.
But the following doesn't work:

Given("the list lecture details are", (List<Lecture> lectures) -> {
	System.out.println("");
	System.out.println(lectures);
});

The error is: cucumber.runtime.CucumberException: Can't use java.util.List in lambda step definition "the list lecture details are". Declare a DataTable argument instead and convert manually with asList/asLists/asMap/asMaps

Do you know if there is a way to make it work ?

Thanks.
