This is a rough example of a Kotlin-based Arquillian test. DatabaseService is, for what it's worth, a CDI-exposed Kotlin-based class as well.

    var service : DatabaseService? = null

    companion object {

            val kotlinRuntime = Maven.configureResolver()

                    .loadPomFromFile("pom.xml")
                    .resolve("org.jetbrains.kotlin:kotlin-stdlib")
                    .withTransitivity().`as`(JavaArchive::class.java)
            return ShrinkWrap.create(WebArchive::class.java, "test.war")
                    .addPackages(true, "com.steeplesoft.kotlinee")
                    .addAsWebInfResource(File("src/main/webapp/WEB-INF/web.xml"))
                    .addAsManifestResource(File("src/main/webapp/WEB-INF/beans.xml"))
                    .addAsLibraries(kotlinRuntime)
        }
    }

    @Test
    fun testService(): Unit {
        Assert.assertNotNull(service)
    }
}

hello...
I tried to apply this example, but I got addAsLibraries as Unresolved reference....
couldn't move ahead...
any solution?
