I believe it has been discussed recently on the forums here that the build is currently broken, and they are working on resolving the issues. I don't know what the status of that is or if that is your problem for sure, but it's a good possibility.

Friday I had no problem building from cvs head. The error above more likely a classpath issue. Could it be that there are older versions of commons logging on your classpath or something like that?

I am facing the same problem as WalterIM with the current files from CVS. If I add commons-logging.jar, hibernate3.jar and dom4j.jar (missing classes) to the classpath, I get:

[jbpmschema] INFO: Configuration resource: hibernate.cfg.xml

BUILD FAILED
C:\jbpm\jbpm.3\jpdl\db\build.xml:38: org.hibernate.HibernateException: hibernate.cfg.xml not found

I had the same problem. I removed the 2 jbpm jar files from the ant lib directory and I succeed to build a step further.

I had a problem with the support.xml that could not be found in my ${user.home}/jbpm/repository. In fact, in the build.xml within the folder 'jbpm.3\designer\jpdl\org.jbpm.gd.jpdl.docs\gpd.userguide', there is a reference to ${user.home}, I think it should be "${docbook-support-dir}/docbook-support/support.xml". A step further

Now, I have problem with the designer
