It appears that MappingUtils has been removed in 2.5 (it was present in
2.4). See :

http://maven.apache.org/plugins-archives/maven-war-plugin-2.4/apidocs/org/apache/maven/plugin/war/util/
http://maven.apache.org/plugins-archives/maven-war-plugin-2.5/apidocs/org/apache/maven/plugin/war/util/

I haven't looked into it but you may need to find a document that either
explains how to migrate, or figure out what MappingUtils did and how the
functionality is provided in 2.5+ .
