I downloaded the 2004/11/11 nightly snapshot of Hibernate 2.1.7 (to be) and tried building it. I ended up with a build failure due to a "bad class file". Anyone have any idea how to resolve this?


Buildfile: build.xml
[taskdef] Could not load definitions from resource clovertasks. It could not be found.

It looks like this may be due to a JDK version discrepancy. I am trying to build using 1.3.1. Does 2.1.7 require JDK 1.4?
