Unresolved slick dependency on Scala 2.11.9 - scala

Question

Similarly to:
Why is UNRESOLVED DEPENDENCIES error with com.typesafe.slick#slick_2.11;2.0.2: not found?
I got the next error message:
events/*:update) sbt.ResolveException: unresolved dependency: com.typesafe.slick#slick-extensions_2.11;3.1.0: not found
My scala build.sbt has:
lazy val events = (project in file("modules/events")).settings(commonSettings).
settings(Seq(libraryDependencies ++= Seq(
cache,
ws,
evolutions,
specs2,

I am also using Scala 2.11.9. I also tried adding
resolvers += "typesafe" at "http://repo.typesafe.com/typesafe/releases/"
but no luck. Any suggestions, please?

Actually slick-extensions is not located in http://repo.typesafe.com/typesafe/releases/. If you will look there you will see that com/typesafe/slick/slick-extensions_2.11/ is empty.
But I have found it here https://typesafe.bintray.com/commercial-maven-releases/com/typesafe/slick/slick-extensions_2.11/3.1.0/
And here some information about slick-extensions: https://index.scala-lang.org/slick/slick/slick-extensions/3.1.0.
They recommend using that:
libraryDependencies += "com.typesafe.slick" %% "slick-extensions" % "3.1.0"
resolvers += Resolver.bintrayRepo("typesafe", "commercial-maven-releases")
