getFile() can return a null, which causes an NPE
While building CXF i encountered an NPE (see below.) It appears to be
possible for org.apache.maven.artifact.Artifact.getFile() to return a null,
which will trigger the NPE in AbstractXSDToJavaMojo.getArguments. It should
throw a MojoExecutionException telling the user that it was unable to resolve a
dependency.
