Groovy:unexpected token when using Grails and Spring security core plugin

Question

I require to add Spring Security core to Grails. I have added the spring core security plugin to a grails 2.3.8 app, using: BuildConfig.groovy plugins { ... compile ":spring-security-core:2.0-RC4" ...

then s2-quickstart sim GUser GRole

The file GUserGRole.groovy contains the following errors:

Groovy:unexpected token: validator @ line 82, column 9. Multiple markers at this line - Groovy:expecting EOF, found 'if' @ line 83, column 4. - Groovy:unexpected token: if @ line 83, column 4.

which corresponds to the following code:

static constraints = {
    GRole validator: { GRole r, GUserGRole ur ->
        if (ur.GUser == null) return
        boolean existing = false
        GUserGRole.withNewSession {
            existing = GUserGRole.exists(ur.GUser.id, r.id)
        }
        if (existing) {
            return 'userRole.exists'
        }
    }
}

How can this be resolved? How can I cleanly add Spring Security core to Grails??

This code doesn't make a whole lot of sense to me. What exactly are you trying to accomplish with this? — rmlan
The code shown is created automatically when I run quickstart after installing the security plugin. — Helen Reeves

s2quick-start uses GrailsNameUtils.getPropertyNameRepresentation to generate the instance fields for your domain classes. Use a name that will generate a suitable field name otherwise the field name and the class name are the same.

 //This is fine - generates 'user'
 GrailsNameUtils.getPropertyNameRepresentation("User") 

 //This is fine - generates 'myUser'
 GrailsNameUtils.getPropertyNameRepresentation("MyUser")

 //Not fine. Generates 'GRole' which is same as your class name
 GrailsNameUtils.getPropertyNameRepresentation("GRole")
