How to exclude jar in final sbt assembly plugin

Question

I need to exclude spark and test dependencies from my final assembly jar. I tried to use provider but it was not working.

libraryDependencies ++= Seq("org.apache.spark" % "spark-core_2.11" % "2.0.1" % "provided")

and execute sbt assembly.

Please help me resolve this issue.

Answer 1

Use exclude option of assembly plugin filtering by direct name or with contains

assemblyExcludedJars in assembly := {
    val cp = (fullClasspath in assembly).value
    cp filter { f =>
      f.data.getName.contains("spark-core") ||
      f.data.getName == "spark-core_2.11-2.0.1.jar"
    }
  }
