sbt assembly akka-stream_2.12:2.4.19 and akka-actor_2.12:2.4.19 are evicted

I want to make fat jar of my project with sbt assembly. Here is my build.sbt: 

name := "projName"

version := "1.0"

scalaVersion := "2.12.1"


libraryDependencies ++= Seq(
  "com.typesafe.akka" %% "akka-stream" % "2.5.3",
  "com.typesafe.akka" %% "akka-actor" % "2.5.3",
  "com.typesafe.akka" %% "akka-http" % "10.0.8",
  "com.fasterxml.jackson.module" %% "jackson-module-scala" % "2.8.6",
  "com.typesafe" % "config" % "1.3.1",
  "org.apache.kafka" % "kafka-clients" % "0.10.2.1",
  "org.knowm.xchange" % "xchange-core" % "4.2.0",
  "org.knowm.xchange" % "xchange-btce" % "4.2.0"
)

assemblyMergeStrategy in assembly := {
  case PathList("META-INF", xs @ _*) => MergeStrategy.discard
  case x => MergeStrategy.first
}

After running

sbt assembly

i got such warning:

[warn] There may be incompatibilities among your library dependencies.
[warn] Here are some of the libraries that were evicted:
[warn]  * com.typesafe.akka:akka-stream_2.12:2.4.19 -> 2.5.3
[warn]  * com.typesafe.akka:akka-actor_2.12:2.4.19 -> 2.5.3
[warn] Run 'evicted' to see detailed eviction warnings

Then i run sbt evicted for more detail and here what i got: 

[warn] There may be incompatibilities among your library dependencies.
[warn] Here are some of the libraries that were evicted:

I know what are eviction warnings but i don't know how to solve that in current situation. Any ideas?

Solution

  • You can safely ignore this message because 2.4 and 2.5 versions are binary compatible, so it is okay to upgrade from 2.4 to 2.5.
