The m2eclipse integration stuff is a complete pain. The API for passing warnings/messages back to Eclipse REQUIRES a File object. If you use a classpath URL or if a schema imports something from an http url or something, it will NPE as we don't have a File object. For the cxf-codegen-plugin, I actually create a "fake" File object to pass that wrappers the appropriate URL. Guess I need to copy that over to the xjc plugin. :-(
