org.jboss.spec:jboss-javaee-web-6.0 (which is propagated to Maven Central) is leaking a dependency to xalan:xalan:2.7.1.jbossorg-2, which is not present in Maven Central.

[DEBUG] org.ocpsoft.rewrite:rewrite-parent:pom:1.0.6-SNAPSHOT
[DEBUG]    org.jboss.spec:jboss-javaee-web-6.0:pom:3.0.1.Final:test
[DEBUG]          xalan:xalan:jar:2.7.1.jbossorg-2:test

Either fix to the correct dependency (something in Central) or push the dependent artifact to Central as well.
