次のbuild.sbtファイルがあります。

import AssemblyKeys._

name := "approxstrmatch"

version := "1.0"

scalaVersion := "2.10.4"

libraryDependencies+="org.apache.spark" %% "spark-core" % "1.0.0"

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

// My merge strategy is specified here.

lazy val app = Project("approxstrmatch", file("approxstrmatch"),
    settings = buildSettings ++ assemblySettings ++ Seq(
    mergeStrategy in assembly <<= (mergeStrategy in assembly) { (old) =>
    {
        case PathList("javax", "servlet", xs @ _*)         => MergeStrategy.first
        case PathList("javax", "transaction", xs @ _*)     => MergeStrategy.first
        case PathList("javax", "mail", xs @ _*)     => MergeStrategy.first
        case PathList("javax", "activation", xs @ _*)     => MergeStrategy.first
        case PathList(ps @ _*) if ps.last endsWith ".html" => MergeStrategy.first
        case "application.conf" => MergeStrategy.concat
        case "unwanted.txt"     => MergeStrategy.discard
        case x => old(x)
        }
    })
  )

mainClass in assembly := Some("approxstrmatch.JaccardScore")
// jarName in assembly := "approstrmatch.jar"

次sbt assembly-merge-strategyのコマンドを実行すると、理解できないエラーが発生します。どんな助けでも感謝します。

approxstrmatch]$ sbt assembly-merge-strategy

assemblyMergeStrategy（別名）という名前の設定がありますassembly-merge-strategy。直接使用しないというだけです。sbt-assembly がそれを使用する方法は、次のassemblyタスクにスコープされます。

mergeStrategy in assembly <<= ....

したがって、シェルから呼び出すために必要なことは次のとおりです。

$ sbt assembly::assemblyMergeStrategy
[info] blabla other things...
[info] <function1>
