Unable to download ZeroMQ dependencies with scala 2.12.6 sbt Akka

Question

I am building app with Scala 2.12.6,Akka and zeroMQ I am trying to add dependency for zeroMQ like this but facing issues while downloading dependencies for zeroMQ. I am trying to add ZeroMQ dependency like this :

val `akka-zeromq`     = "com.typesafe.akka"      %% "akka-zeromq"   % "2.1-M1"

Below section explains sbt resolvers I am using : resolvers += Resolver.url("bintray-sbt-plugins", url("https://dl.bintray.com/sbt/sbt-plugin-releases/"))(Resolver.ivyStylePatterns), resolvers += Resolver.bintrayRepo("pqw", "maven"), version := "0.0.1", fork := true, parallelExecution in Test := false, autoCompilerPlugins := true, if (formatOnCompile) scalafmtOnCompile := true else scalafmtOnCompile := false

I think I did everything correct but still facing below issues while trying to run project with command sbt stage publishLocal

Please let me know if you can provide any help for this.

Answer 1

From what I can see on https://mvnrepository.com/artifact/com.typesafe.akka/akka-zeromq, version M-1 is not released on maven central, but exists on typesafe repo.

I tried with this minimal example:

resolvers += "Typesafe maven releases" at "http://repo.typesafe.com/typesafe/maven-releases/"

// https://mvnrepository.com/artifact/com.typesafe.akka/akka-zeromq
libraryDependencies += "com.typesafe.akka" % "akka-zeromq" % "2.1-M1"

Reload sbt and update. Maybe try newer dependency version.
