How to refer to one configuration variable from other configuration variable inside Config.groovy

config, grails, groovy

Solution

You need to declare a variable:

def rootVar = 'a'
grails.variable1 = rootVar
grails.varibale2 = "${rootVar}bc"

Or you might be able to do it via a closure (not tested):

grails.variable1 = 'a'
grails.varibale2 = { -> "${grails.variable1}bc" }()

Problem

For example: Config.groovy: ``` // ... grails.variable1 = "a" grails.varibale2 = "${grails.variable1}bc" //... ``` UPDATE 1 Way shown above works with grails 2.2.3. For older versions of grails please use solution @tim_yates suggested
