Question

i'm trying to run a test command in sbt-shell of intellij ide for this -> [https://github.com/theiterators/akka-http-microservice#akka-http-microservice-example] project then it shows Akka version conflict. how to resolve it?
this is build.sbt

[info] ServiceSpec *** ABORTED ***
[info] java.lang.IllegalStateException: You are using version 2.6.14 of Akka, but it appears you (perhaps indirectly) also depend on older versions of related artifacts. You can solve this by adding an explicit dependency on version 2.6.14 of the [akka-slf4j] artifacts to your project. Here's a complete collection of detected artifacts: (2.6.11, [akka-slf4j]), (2.6.14, [akka-actor, akka-protobuf-v3, akka-stream, akka-testkit]).

Answer 1

Adding
"com.typesafe.akka" %% "akka-slf4j" % akkaV
to the Seq in your libraryDependencies block should resolve this. In general in Akka it's best to not rely on transitive dependencies.
