Unable to resolve class org.scribe.builder.api.FacebookApi in grails-oauth-scribe for grails 3

Question

This is probably a rookie mistake but I can't seem to find it, been trying for 2 days. I'm trying to integrate a simple facebook login in my grails 3 app using the grails-oauth-scribe plugin which utilizes the Scribe oauth API. So it is natural that installing the plugin will install these dependency API classes. But I think it does'nt because when I import the FacebookAPI in my application.groovy

import org.scribe.builder.api.FacebookApi

oauth {
    providers {
        facebook {
            api = FacebookApi
            key = 'my key'
            secret = 'my secret'
            successUri = "${application.baseUrl}/hello/oauthFb"
            callback = "${application.baseUrl}/oauth/facebook/callback"
        }
    }
}

I get this error

    $ grails compile --stacktrace --verbose                                              [21:54:04]

build.gradle dependencies part

    testRuntime "net.sourceforge.htmlunit:htmlunit:2.18"
}

I understand that it is a class resolution error so i have tried to include the scribe jar manually but nothing happens. I will post the application.yml if it helps

oauth:
    providers:
        facebook:
            api: org.scribe.builder.api.FacebookApi
            key: 'my key'
            secret: 'secret'

everything seems alright to me, must be something silly.

Answer 1

Try adding this dependency:

    dependency {
        compile 'org.scribe:scribe:+'
    }
