java.lang.NoSuchFieldException: handle Embedded MongoDB with play framework

Question

I'm trying to enable in-memory mongodb in testing, I am using simplyscala to do the work.

class controllerSpec extends PlaySpec with GuiceOneAppPerTest with Injecting with BeforeAndAfterAll with MongoEmbedDatabase{

  //declares a variable which will hold the reference to running mongoDB Instance
  var mongoInstance: MongodProps = null
  // Start In-memory Mongo instance in before statement
  override def beforeAll(): Unit =
    try{
      val rnd = new scala.util.Random
      val range = 12000 to 36000
      val portNum = range(rnd.nextInt(range length))
      mongoInstance = mongoStart(portNum) } //Try starting mongo on random port number
    catch { case ex:Exception => } // Handle exception In case local mongo is running//code to run before all tests starts
  override def afterAll(): Unit = mongoStop(mongoInstance)

However I have error :

[info] controllerSpec:

Does it have something to do with the BeforeAndAfterAll? Please tell me if I did anything wrong thank you.

Upgrade the version of the Embedded MongoDB dependency test driver to 3.4.3

Gradle:

testImplementation 'de.flapdoodle.embed:de.flapdoodle.embed.mongo:3.4.3'

pom.xml

<dependency>
    <groupId>de.flapdoodle.embed</groupId>
    <artifactId>de.flapdoodle.embed.mongo</artifactId>
    <version>3.4.3</version> <!-- make this version a property instead-->
    <scope>test</scope>
</dependency>
