title: Grails: Turn off Codenarc NoDef rule for controller actions
body: <p>Is there a way to turn off the Codenarc NoDef rule for Grails controller actions? The rule is a good practice to follow in general but since some actions return a value and some don't, we typically use def to support all variants. I looked around a bit to see if this rule can be turned off for controller actions but came up empty. Does anyone know?</p>
