The original problem is raised because the XIFF project has decided to change their package name from "org.jivesoftware.xiff" to "org.igniterealtime.xiff" in their trunk of svn repository. Since the SparkWeb source repository link external svn repository (XIFF trunk) to make a complete source tree, the XIFF refractor breaks the SparkWeb trunk build effectively.
