1. sbt-assembly 추가(project/assembly.sbt파일에 아래 내용을 추가함)

  addSbtPlugin("com.eed3si9n" % "sbt-assembly" % "0.14.3")

2. project.sbt(혹은 build.sbt) 파일에 아래의 내용을 추가한다.

(scala 2.10.4에 spark 1.5.0을 사용하는 하는 프로그램을 작성하는 경우임)

import sbtassembly.AssemblyPlugin._

name := "icbms"

version := "1.0"

 //scalaVersion := "2.11.8"

scalaVersion := "2.10.4"

resolvers += "Akka Repository" at "http://repo.akka.io/releases/"

libraryDependencies ++= Seq(

("org.apache.spark" %% "spark-core" % "1.5.0" % "provided")

.exclude("org.mortbay.jetty", "servlet-api").

    exclude("commons-beanutils", "commons-beanutils-core").

    exclude("commons-collections", "commons-collections").

    exclude("commons-logging", "commons-logging").

    exclude("com.esotericsoftware.minlog", "minlog").exclude("com.codahale.metrics", "metrics-core")

,

"org.apache.spark" % "spark-streaming-kafka_2.10" % "1.6.2" ,

"org.apache.avro" % "avro" % "1.7.7" 

)

assemblyMergeStrategy in assembly := {

    case PathList("javax", "servlet", xs @ _*) => MergeStrategy.last

    case PathList("javax", "activation", xs @ _*) => MergeStrategy.last

    case PathList("org", "apache", xs @ _*) => MergeStrategy.last

    case PathList("com", "google", xs @ _*) => MergeStrategy.last

    case "META-INF/ECLIPSEF.RSA" => MergeStrategy.last

    case "META-INF/mailcap" => MergeStrategy.last

    case "META-INF/mimetypes.default" => MergeStrategy.last

    case "plugin.properties" => MergeStrategy.last

    case "log4j.properties" => MergeStrategy.last

    case x =>

        val oldStrategy = (assemblyMergeStrategy in assembly).value

        oldStrategy(x)

}

3. fat jar만들기(프로젝트의 project 폴더에서 아래의 명령을 실행한다)

 sbt clean

 sbt update

 sbt compile

 sbt package

 sbt assembly

혹은 sbt clean update compile package assembly 를 연속 실행해도 된다.
