Re: Not able to pass multiple arguments to javac

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,

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.
