How to force a parameter to be the last?

[giaphattram]

I have one parameter and a number of options. How to configure so that the parameter must take the last position?

There's no way in picocli to enforce that positional parameters need to follow the named options.

So any validation will need to be done in the application.

One idea is to get the ParseResult object from the CommandLine object, and call the matchedArgs or expandedArgs method on it to get the matched arguments or the original command line arguments. Then check in your application logic that the last element in the list was the positional parameter.
