groovy executed as a script. groovy script before running converted into a class. all the code (except methods/functions) executed as a method main in java. and you can't declare static variables inside the method. but you can declare inner class with static vars in groovy script like: class MyConst { static int i = 123 } and access it from script: MyConst.i
