Unresolvable dependency in parent pom. See here http://tinyurl.com/3aob2t for description of problems this causes. Extract of important bit:
"The problem seems to be in spring-ws POM
(which is parent of spring-ws-core) which contains artifact spring-ws-doc
in its dependencyManagement section. Maven doesn't find spring-ws-doc."
Presumably spring-ws-doc is not a jar, so dependening on it is a bad idea?
