Description

Me and Tomáš Hůrka were trying to write a rule to add @SuppressWarnings annotation to all class from a project:

'SuppressWarnings in all classes':
$mods$ class $name extends $extends$ implements $implements$

{ $members$; }
=>
'Do it!':
@SuppressWarnings("all") $mods$ class $name extends $extends$ implements $implements$ { $members$; }

;;

this is the error that gets generated when the "Do It!" action is invoked:
