Just because you use exec doesn't mean you are os-dependent. If the same
exec-utable is available on all os's, then you maintain os independence.
I use executables in my builds (i.e. m4, isql, sqlplus) and the same
build files work on Windows, Solaris and RH.

Hi Stefan,
I understand that I can use <exec>, but that would make it os-dependent.
I want the same ant script to run on windows and solaris. Any way out?

Hi,
I have the following script

	<java classpathref=3D"classpath" classname=3D"java_cup.Main">
		<arg value=3D"-symbols"/>
		<arg value=3D"${file}Sym"/>
		<arg value=3D"-parser"/>
		<arg value=3D"${file}"/>
		<arg value=3D"-package"/>
		<arg value=3D"mypackage.${file}"/>
		<arg value=3D"&lt; ${file}.cup"/>
	</java>

I get the following problem:
    [java] Unrecognized option "< condition.cup"

    [java] Usage: java_cup [options]
    [java]   and expects a specification file on standard input.
    [java]   Legal options include:
    [java]     -package name  specify package generated classes go in
.....

The value of the variable file is "condition"
Anybody ever done this through ant?? Any pointers??

Regards,
Sadaf
