Script Task In Ant

[Francisco Tolmasky]

Hello, I am attempting to use JavaScript within ant and am running  
into a few difficulties.
I used to be able to do the following in Mac OS X Tiger just fine:

        <script language = "javascript" src = "whatever.js">
                /* whatever */
        </script>

However, since moving to Mac OS X Leopard, I get the following error:

java.lang.ClassNotFoundException:  
org.apache.tools.ant.util.optional.ScriptRunner

I currently have bsf.jar, js.jar (rhino) and commons-logging-1.1.jar  
in my ant lib directory.
The ant version on Leopard is 1.7.0.  Do I need to update something or  
add a lib?

Thanks,

Francisco
