OAuth 2.0 for Grails without Spring security

Question

I am currently implementing Shiro-Authentication along with OAuth for Google SignIn. It all works great and lets me authenticate a gmail account against a users email in my database. My build config looks as follows:

    //User roles and permissions
    compile (":shiro:1.2.0") {
        excludes "servlet-api"
        excludes "shiro-quartz"
    }

    //Google SignIn
    compile ":oauth:2.1.0" 

The only issue I am having is that when google requests permission for my application, I get this:

When I was expecting something more like this:

It is clearly still using OAuth 1.0 and not 2.0. I have read many questions on here and the closest I have found is this Google consent screen not shown as expected .

The only issue with this implementation is that it uses Spring security and I am using Shiro. When I try use the spring plugin, I keep coming up against this issue when I try to compile it:

| Error The following artifacts could not be resolved: org.springframework.security:spring-security-core:jar:3.2.0.RC1, org.springframework.security:spring-security-web:jar:3.2.0.RC1: Could not find artifact org.springframework.security:spring-security-core:jar:3.2.0.RC1 in grailsCentral (http://repo.grails.org/grails/plugins)

Any tips or suggestions are greatly appreciated.

Cheers.
