I don't want to see the Eclipse error log be filled up with new content for *every* build. Will make it almost impossible for users of m2eclipse to report issues
about other plugins which only send content to error log that *really* are eclipse level errors ;)

Why not send this to a separate log and open a separate error logger on it instead of polluting the main one?
