I haven't looked at the code, but based on some historical emails on
this list it seemed like multiple <compilerArgument> tags were the way
to go. One possible fix would be to take away the quoting of these
arguments, but I'm not sure if this wouldn't create some new
unintended side-effects.
It certainly sounds like this is something that could stand to be improved.

My first assumption was indeed wrong, because I used java 1.5 to check
for the existence of those properties. Also, your description (They are
not supported by javac.) set me on the wrong track. See my other mail
for the how and why of this error.
And indeed, in the current implementation, when you have multiple
"compilerArgument" elements only one is taken. I guess it just runs
setCompilerArgument multiple times.

I doubt those message come from javac. They were printed by maven when
I ran it with -X option. Tell me what is the option that is *not*
supported by javac. AFAIK, all the options that I want to pass are
very much supported by javac. Check out the documentation [1] of javac
that comes with Sun JDK 6.
More over, JDK 6 compiler allows to provide plugins to javac. In order
to configure the plugin user may have to pass options that are *not*
meant for javac itself, instead they are meant for the javac plugin.
Such options will never be supported by maven-javac-plugin, hence
compilerArgument is the only way to use them. In case of Sun JDK, any
javac option starting -A is passed onto the plugin. An example is
available at [2]. I actually faced all my maven issues while
developing that plugin.
My observation is that when multiple compilerArgument is used, only
the last one is considered.
Thanks,

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?

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.

Ignore my earlier email. The suggestion actually does *not* work.
When I
run with -X option, it shows only the last compilerArgument. See the
following output:

As suggested in [1], I tried configuring maven-compiler-plugin like
this:
<compilerArgument>-nowarn -verbose</compilerArgument>
But it causes compilation failure. Details given below:
Failure executing javac, but could not parse the error:
javac: invalid flag: -nowarn -verbose
How can I pass multiple arguments to javac?
Thanks,
Sahoo
