How to access global variables in groovy

Question

I have a really simple groovy script-

import groovy.transform.Field

@Field final static String VARIABLE = 'Variable'

static void main(String[] args) {
    println VARIABLE
}

But the output is empty, how can I make a global, static constant in groovy and use it in static methods?

Answer 1

to use a global static constant i would use this syntax - maybe not perfect but always working:

class Const{
  final static String VARIABLE='value'
}

println "VARIABLE=${Const.VARIABLE}"

avoid using static void main() in groovy scripts - this way you could conflict with groovy script-to-class transformation
