Unit testing Quartz plugin for Grails

I have some trouble writing the most basic unit test for a job. My problem can be recreated by creating a new job by running grails create-job my in the console.

This will create two files

• MyJob.goovy (under the default package myApp - resides in test\unit\myApp)
• MyJobSpec.groovy (under the default package myApp - resides in grails-app\jobs\myApp)

Now if i try to use the job MyJob in the test, as example

import myApp.MyJob //This is not resolved

@TestMixin(GrailsUnitTestMixin)
class MyJobSpec extends Specification {
    def MyJob myJob

I get the compiler error Groovy:unable to resolve class MyJob. Everything so far was automatically created by the plugin. What is going on here? Is there something i did wrong / how do i get this to work?

Using grails 2.3.11.
