Problem displaying Components

I am a new user too Vaadin.

I have installed Grails 3.1.6 and the grails vaadin plugin at and followed the instructions there.

I have edited the IndexView.groovy file located in src/main/groovy/com.key2publish/ like so:

package com.key2publish

import com.vaadin.navigator.View
import com.vaadin.navigator.ViewChangeListener
import com.vaadin.ui.CustomComponent
import com.vaadin.ui.Label
import com.vaadin.ui.VerticalLayout
import com.vaadin.ui.*

class IndexView extends CustomComponent implements View {

IndexView() {
def root = new VerticalLayout()

// Add your code here
def myLabel = new Label(“help”)

compositionRoot = root


void enter(ViewChangeListener.ViewChangeEvent event) { }

The result I expect when going to localhost:8080/vaadin is that a label with “help” would appear,
but I get a loading icon with a green bar running in the top of the screen. Then the page turns blank and stays blank. Without displaying the label

I am working with IntelliJ IDE 2016.3.3 Could anyone tell me what I might have done wrong?
Since I don’t get an error message in IntelliJ whatsoever. It compiles and runs ok.
