Please use maven-2.0.6 (2.0.8 also seems to work) when building, 
juddi-tomcat uses dependency properties which are broken in recent versions of maven.

You will see an error like:

Caused by: java.io.FileNotFoundException: 
C:\development\projects\jUDDI_v3\juddi-tomcat\${maven.dependency.tomcat.apache-tomcat.zip.path} 
(The system cannot find the file specified)

where the ${maven.dependency.tomcat.apache-tomcat.zip.path} should have been set by maven.
