I've below build.sbt file -

ThisBuild / version := "0.1.0-SNAPSHOT"

ThisBuild / scalaVersion := "2.13.7"

val akkaVersion = "2.6.18"

lazy val root = (project in file("."))
  .settings(
    name := "akka-sbt-multijvm-issue"
  )

libraryDependencies ++= Seq("com.typesafe.akka" %% "akka-actor" % akkaVersion,
"com.typesafe.akka" %% "akka-stream" % akkaVersion,
 "com.typesafe.akka" %% "akka-cluster" % akkaVersion)

I've below main code -

package com.example

object MaterializerApp  extends App {

  import akka.stream.Materializer
}

when I compile the code I get the below error -

sbt clean compile

Note: When I change the akkaVersion to 2.6.17, the compilation succeeds.

How can I fix this error?
