Arity not working

[Chris08tm]

I have the method:

 @Command(command = "create")
    public String create(
            @Option(
                    longNames = {"fp", "filePath"},
                    arity = OptionArity.EXACTLY_ONE,
                    required = true) String filePath){
        return "test";
    }

But after running the command

shell:>c --fp
Not enough arguments for option 'fp', requires at least '0'

I have tried using arityMin = 1 and arityMax = 1, but regardless it always says " requires at least '0' "
I am using 'springShellVersion' = "3.1.5"

Are you sure you're using correct command as in your sample it's mapped to create.

Also using just --fp, as exactly one option argument is required, should result two errors, something like:

Not enough arguments for option 'fp', requires at least '0'
Missing mandatory option '--fp'

Yes, sorry I shorted it to "c" after since I didn't want to continue to type "create" over and over, this is the annotation as it stands currently:
@Command(command = "c")
The error is correct, but my question is, shouldn't it return "requires at least '1'" rather than "requires at least '0'"

doh, you're right, I was totally eyeing this wrongly. In this case parser internally reports NOT_ENOUGH_OPTION_ARGUMENTS but is passing wrong count to message template which is then reported back to user.
