  Maven配置文件的概念在sbt / Ivy中作为配置进行转换 . 您可以在配置中定义设置，并让sbt-assembly生成两个jar . 您可以通过添加 % "config" 将libraryDependency添加到特定配置 . 但是，这需要项目预先了解配置 .

  在 build.sbt （要求sbt 0.13.0或以上）：

  import AssemblyKeys._
  
  val Dispatch10 = config("dispatch10") extend(Compile)
  val TestDispatch10 = config("testdispatch10") extend(Test)
  val Dispatch11 = config("dispatch11") extend(Compile)
  val TestDispatch11 = config("testdispatch11") extend(Test)
  
  val root = project.in(file(".")).
    configs(Dispatch10, TestDispatch10, Dispatch11, TestDispatch11).
    settings( 
      name := "helloworld",
      organization := "com.eed3si9n",
      scalaVersion := "2.10.2",
      compile in Test := inc.Analysis.Empty,
      compile in Compile := inc.Analysis.Empty,
      libraryDependencies ++= Seq(
        "net.databinder.dispatch" %% "dispatch-core" % "0.10.0" % "dispatch10,testdispatch10", 
        "net.databinder.dispatch" %% "dispatch-core" % "0.11.0" % "dispatch11,testdispatch11",
        "org.specs2" %% "specs2" % "2.2" % "test",
        "com.github.scopt" %% "scopt" % "3.0.0"
      )
    ).
    settings(inConfig(Dispatch10)(Classpaths.configSettings ++ Defaults.configTasks ++ baseAssemblySettings ++ Seq(
      test := (test in TestDispatch10).value,
      test in assembly := test.value,
      assemblyDirectory in assembly := cacheDirectory.value / "assembly-dispatch10",
      jarName in assembly := name.value + "-assembly-dispatch10_" + version.value + ".jar"
    )): _*).
    settings(inConfig(TestDispatch10)(Classpaths.configSettings ++ Defaults.configTasks ++ Defaults.testTasks ++ Seq(
      internalDependencyClasspath := Seq((classDirectory in Dispatch10).value).classpath
    )): _*).
    settings(inConfig(Dispatch11)(Classpaths.configSettings ++ Defaults.configTasks ++ baseAssemblySettings ++ Seq(
      test := (test in TestDispatch11).value,
      test in assembly := test.value,
      assemblyDirectory in assembly := cacheDirectory.value / "assembly-dispatch11",
      jarName in assembly := name.value + "-assembly-dispatch11_" + version.value + ".jar"
    )): _*).
    settings(inConfig(TestDispatch11)(Classpaths.configSettings ++ Defaults.configTasks ++ Defaults.testTasks ++ Seq(
      internalDependencyClasspath := Seq((classDirectory in Dispatch11).value).classpath
    )): _*)
  

  要在配置中运行程序集任务，您需要说：

  > dispatch11:assembly

  [info] 
  [info] The 'Hello world' string should
  [info] + contain 11 characters
  [info]
