Subject RE: Building on windows
Date Thu, 10 Mar 2011 18:41:14 GMT
Hi Erick,

I regularly build on Windows, and I've never encountered this problem.

My environment: I'm on Windows 7 64-bit, using Oracle Java 1.6.0_23 64-bit and Ant 1.7.1.

My Ant installation directory doesn't have any jasper libs in it ("find . -name '*ja?sp*.jar'"
under cygwin bash shell returns nothing), and the output from "ant -diagnostics", which shows
the ant classpath and boot classpath, doesn't show anything named "*jsp*" or "*jasper*".

The "jasper" <taskdef> under the "test-jsp" target includes everything (recursively)
under solr/example/lib/ in the classpath for the "JspC" task invocation, so the compiler,
AFAICT, should be coming from somewhere under solr/example/lib/jsp/.

My guess is that the other jasper jars in your classpath (outside of solr/example/lib/jsp/)
are blocking successful completion of the Solr "test-jsp" target for you.
