Grails 3 mail plugin not working

Using Grails 3 it's impossible to get an instance of mailService object, DI is not working:

build.gradle

compile "org.grails.plugins:mail:1.0.7"
testCompile "org.grails.plugins:mail:1.0.7"

application.groovy

environments {
    development {
     //grails.logging.jul.usebridge = true
     grails.plugin.springsecurity.debug.useFilter = true
     grails {
        mail {
            host = "main.mydomain.com"
            port = 25
            username = "login"
            password = "password"
            props = ["mail.smtp.auth":"true"]

        }
    }
    grails.mail.default.from="[email protected]"

    }
    production {
        grails.logging.jul.usebridge = false
    }
}

testController:

import groovy.xml.MarkupBuilder
import org.slf4j.Logger
import org.slf4j.LoggerFactory
import org.springframework.security.access.annotation.Secured

@Secured(["hasRole('PERM_LOGIN')"])
class TestLogController {

    def Logger logger = LoggerFactory.getLogger(this.getClass())
    def mailService

    def index() {

        logger.info("Hello");

        mailService.sendMail {
           to "[email protected]"
           subject "Hello Fred"
           text "How are you?"
        }       
    }
}

The following error occurs:

Caused by NullPointerException: Cannot invoke method sendMail() on null    object
->>   18 | index                    in TestLogController.groovy

So mailService has not been injected properly to cotroller class or to integration test:

import grails.test.mixin.integration.Integration
import grails.util.Holders
import org.slf4j.Logger
import org.slf4j.LoggerFactory
import org.springframework.context.ApplicationContext
import spock.lang.Shared
import spock.lang.Specification

@Integration
class SendMailSpec extends Specification {

    @Shared Logger logger
    @Shared def mailService

    def setup() {
        logger = LoggerFactory.getLogger(this.getClass())
        ApplicationContext ctx = Holders.grailsApplication.mainContext
        mailService = ctx.getBean("mailService");

    }

    def cleanup() {
    }

    void "test mailService is not null"() {
       expect:
       mailService !=null
    }

    void "test send mail"() {
      expect:"mail send"
       mailService.sendMail {
          to "[email protected]"
          subject "Hello Fred"
          text "How are you?"
       }
    }
}

What is a problem ??

UPDATE: It was wrong mail plugin version, this one works fine:

compile "org.grails.plugins:mail:2.0.0.RC2"

here's the current version (at the moment of writing this) to install : 

compile 'org.grails.plugins:mail:2.0.0.RC6'

Here's the link to the main plugin (I don't know why google shows only the old versions) :
