Your current pull as it stands has removed the new line at the end of file, which will cause the build to fail. Please adjust. 

Also, I am not sure that the ability to override a single file is necessarily a good idea. I am more of the idea that it might be better to simply provide a new directory `spring-configuration-overrides` next to where `spring-configuration` lives and have the context loaded in such a way that configuration in that directory overrides the default. That way, You can override all beans in all context files with just the change you want to have, rather than copying down the entire file and have it match the name. (I have had to assist folks who simply had the name misplaced).
