I just wanted to mention a thing I hacked together a little while ago. It's made it much easier to manage coding standards stuff. Your mileage may vary.
NetBeansDrupalComposed is a tiny Composer-based project that pulls in all the stuff you need to do coding standards reviews for Drupal.
Basically you install it by saying
composer create-project mile23/netbeansdrupalcomposed and it builds a little project for you. Then it tells you where
phpcs and other tools are located within that project. You copy-paste those paths into NetBeans and then start being done.
It lives here, as a Drupal.org sandbox project: https://drupal.org/sandbox/mile23/2197899
