How to specify source jar for Cucumber stepdef

I have some scenarios which call a stepdef from a jar included as dependency.

Now, I want to maintain 2 separate versions for same stepdef into 2 different jars.

So, I need few scenarios to use version 1 and others to use version 2 of the stepdef.

How do I do this with cucumberoptions, specifically mentioning jar source in the glue.
