Training / Learning / Certification - Cannot run build_resources.xml in Ant

I'm working through the second module of the "WJ-3101A: J2EE and the Component Model" training course, and I cannot run this config script:

asant -f build_resources.xml installDB

I receive the following error:

Buildfile: build_resources.xml
