incompatible akka-http versions with elasticmq version

Question

im trying to run sqs server using elasticmq-rest-sqs:

"org.elasticmq" %% "elasticmq-rest-sqs" % "0.14.7"

and my akka dependencies are:

  val akka = Seq(
    "com.lightbend.akka" %% "akka-stream-alpakka-sns" % "0.15",
    "com.typesafe.akka" %% "akka-testkit" % "2.5.8" % Test withSources(),
    "com.typesafe.akka" %% "akka-stream-testkit" % "2.5.8" % Test withSources(),
    "com.lightbend.akka" %% "akka-stream-alpakka-sqs" % "0.15"
  )

now in my test im writing:

 // sqs server
  val sqsServer: SQSRestServer = SQSRestServerBuilder.withPort(4576).withInterface("localhost").start()
  sqsServer.waitUntilStarted()

and i get the following error:

A needed class was not found. This could be due to an error in your runpath. Missing class: akka/http/impl/util/SettingsCompanion java.lang.NoClassDefFoundError: akka/http/impl/util/SettingsCompanion

its versioning thing for sure since im using it the same way in another project, but with play 2.6 (not sure if it has anything to do with it)

if im downgrading elasticmq version i get this error:

An exception or error caused a run to abort: java.lang.NoClassDefFoundError: akka/http/scaladsl/settings/RoutingSettings java.lang.BootstrapMethodError: java.lang.NoClassDefFoundError: akka/http/scaladsl/settings/RoutingSettings

please help :/

For me, the following version is working: (also matched this problem but fixed it with version)

    "org.elasticmq" %% "elasticmq-rest-sqs" % "0.15.2" 



"com.typesafe.akka" %% "akka-testkit" % "2.5.8" % Test withSources(),
"com.typesafe.akka" %% "akka-stream-testkit" % "2.5.8" % Test withSources(),
"com.lightbend.akka" %% "akka-stream-alpakka-sqs" % alpakkaVersion

val alpakkaVersion = "1.0-M2"

and:

"com.typesafe.play" % "sbt-plugin" % "2.7.2"
