I'm trying to run hibernate
tools in an ant build to generate ddl from my JPA annotations. Ant dies on the taskdef tag. I've tried with ant 1.7, 1.6.5, and 1.6 to no avail. I've tried both in eclipse and outside. I've tried including all the hbn jars in the hibernate-tools path and not. Note that I based my build file on this post:
http://stackoverflow.com/questions/281890/hibernate-jpa-to-ddl-command-line-tools
I'm running eclipse 3.4 with WTP 3.0.1 and MyEclipse 7.1 on Ubuntu 8.
