Subject Re: Problem compiling plugins
Date Fri, 09 May 2008 17:00:15 GMT
Hi,

You are missing some ant jars.  I'm not sure which ones, but it looks like the class that
cannot be found is TraXLiaison , so once you google you'll find which optional ant jar this
is in.  Get that jar, put it in your ant home's lib dir and try again.
