RE: Not able to pass multiple arguments to javac

by Nick Stolwijk :: Rate this Message:

The fault message you see is actually from javac itself. You're trying to add options that are not supported by javac. All javac options are "supported" by the mojo, it simply passes them to javac.

Why would you want to add options to javac which are not supported by javac?

With regards,

Nick Stolwijk

Yes, I knew that approach, but the options I actually want to pass are
not supported by the mojo. nowarn and verbose were just used as
examples; I want to pass -proc:none and -implicit. They are not
supported by javac. There are many such options which are not supported
by the mojo. I thought compilerArgument is the way to use them. But, it
is *not* working.

Thanks,
Sahoo
