Lombok is a small, but very useful library that helps to remove smelly Java boilerplate. Are you tired of writing getters and setters, builders or even constructors? Want to generate toString() / equals() / hashCode() or immutable class very fast? Lombok spices up these and many other experiences by allowing you to achieve small goals declaratively and effectively. This presentation accompanied live coding session at JEEConf 2016
