Can not show suggestion with @Field on Groovy

Hi guys,

When I use @Field for global variables on Groovy.

Intellij can not show any suggestions such as class properties or defined method

Position.Groovy

class Position {

    def Left
    def Right
    def Middle
    def methodMissing(String name, args) {
        return 1
        // implementation of dynamic method synthesis
    }
}

Main.groovy

import groovy.transform.Field

@Field pos = new Position()


def main () {
    pos.methodMissing(name)
}
