I have found an issue with the new ANT 1.6.2 version. Using the WAR or JAR task, empty directories are not created. I verified on both Windows and UNIX that 1.6.1 doesn't have this problem but 1.6.2 does. I checked the ANT bug database and found that someone submitted a bug for the same reason but with the ZIP task. I added a new bug report.
Has anyone else seen this and have found a work around?
