changing startup MVC group in Application.groovy issue - groovy

Question

I've created new Groffin module using IntelliJ. I was prompted for create-app command.
Creating a module was fine, and as you know, by default, when you ran an app, it shows applet with default content "Content goes here".
Next, I've added a second login MVC group in Application.groovy:
application {
title = 'Soms'
startupGroups = ['login']
// Should Griffon exit when no Griffon created frames are showing?
autoShutdown = true
// If you want some non-standard application class, apply it here
//frameClass = 'javax.swing.JFrame'
}
mvcGroups {
// MVC Group for "soms"
'soms' {
model = 'soms.SomsModel'
view = 'soms.SomsView'
controller = 'soms.SomsController'
}
// MVC Group for "login"
'login' {
model = 'soms.LoginModel'
view = 'soms.LoginView'
controller = 'soms.LoginController'
}
}
I've also created:
LoginModel.groovy (groovy class)
LoginController.groovy (groovy class)
LoginView.groovy (groovy script)
in the corresponding folders.
When I run project, it's giving errors:

The same error happens when I try to run from command prompt.

}
LoginController.groovy:
package soms
class LoginController {
def model
def view
}

Answer 1

I found out that my LoginController.groovy was incomplete.
Now it's working and the correct LoginController.groovy as follows:
package soms
import griffon.transform.Threading
class LoginController {
def model
def view
#Threading(Threading.Policy.SKIP)
def reset = {
model.login = ''
model.password = ''
}
def submit = {
println "Login: ${model.login}"
println "Password: ${model.password}"
}
}
