mvn hibernate3:hbm2ddl "no hibernate.cfg.xml configuration provided"

Ran mvn clean on parent project.

Then switched to simple-webapp directory and ran mvn hibernate3:hbm2ddl as explained on page 93 of the Definitive Guide.

Then got the following error:

C:\projects\simple-project\simple-webapp>set M2_HOME=C:\dev\apps\apache-maven-2.
