When I try to sbt build my project, the project build fails with an "extracting product structure failed" error. I am suspecting something related to the versions I am using for Alpakka and Akka.
Here is my build.sbt file:
lazy val akkaHttpVersion = "10.2.4" // "10.1.11"
lazy val akkaVersion = "2.6.14" // "2.5.31"
val JacksonVersion = "2.10.5.1"
lazy val root = (project in file(".")).
settings(
inThisBuild(List(
organization := "com.example",
scalaVersion := "2.13.4"//"2.12.11"
)),
name := "XYZ",
libraryDependencies ++= Seq(
"org.orekit" % "orekit" % "10.3",
"com.typesafe.akka" %% "akka-http" % akkaHttpVersion,
"com.typesafe.akka" %% "akka-http-spray-json" % akkaHttpVersion,
"com.typesafe.akka" %% "akka-actor-typed" % akkaVersion,
"com.typesafe.akka" %% "akka-stream" % akkaVersion,
"ch.qos.logback" % "logback-classic" % "1.2.3",
"com.typesafe.akka" %% "akka-http-testkit" % akkaHttpVersion % Test,
"com.typesafe.akka" %% "akka-actor-testkit-typed" % akkaVersion % Test,
"org.scalatest" %% "scalatest" % "3.1.4" % Test,
"org.ehcache" % "ehcache" % "3.1.3",
"org.apache.httpcomponents" % "httpclient" % "4.5.13",
"org.scala-lang.modules" %% "scala-parallel-collections" % "0.2.0",
"org.apache.sling" % "sling-maven-plugin" % "2.4.2",
"com.fasterxml.jackson.module" % "jackson-module-scala" % "2.0.2",
"com.fasterxml.jackson.core" % "jackson-databind" % JacksonVersion,
"com.typesafe.akka" %% "akka-stream-kafka" % "2.0.7",
"com.lightbend.akka" %% "akka-stream-alpakka-reference" % "2.0.2"
)
)
When I remove the alpakka dependency at the end of the library, the error goes away but I am unable to to build project because of the missing alpakka dependency.
Ultimately, I am just trying to implement this: https://akka.io/alpakka-samples/http-csv-to-kafka/step4.html

When running sbt clean compile, I get the following error stack:

It seems that I needed to use "com.lightbend.akka" %% "akka-stream-alpakka-csv" % "2.0.2" instead of "com.lightbend.akka" %% "akka-stream-alpakka-reference" % "2.0.2".
