Switching Environments in Grails 3 BootStrap

Over the iterations of grails, the best method to do this has changed. But if you want to execute grails code only within a specific environment in grails 3, you can use the static methods on the grails.util.Environment class.

Eg:

switch (Environment.getCurrent()) {

    case Environment.DEVELOPMENT:
        20.times {
            //do some thing
        }
        break;
    case Environment.PRODUCTION:
        2.times {
            //do some other thing
        }
        break;
}
