Tracking down a problem with doing a build of ant was hindered by an error message with insufficient information. The errors thrown by DirectoryScanner should (imho) report the value of the basedir that is not being found (or that is not a directory). This is a simple change to a couple lines.
This bug report has nothing to do with jakarta-oro and apparently should have been reported to the Ant team. I'm reassigning it to ant-dev and changing the product from ORO to Ant. It had originally been assigned to tomcat-dev for some reason.
fixed in nightly-build 2001-05-04
