如何在sbt-assembly jar中包括測試依賴項？

Question

我無法將測試依賴項打包在測試程序罐中。 這是我的build.sbt的摘錄：

...

name := "project"

scalaVersion := "2.10.6"

assemblyOption in (Compile, assembly) := (assemblyOption in (Compile, assembly)).value.copy(includeScala = false)

fork in Test := true

parallelExecution in IntegrationTest := false

lazy val root = project.in(file(".")).configs(IntegrationTest.extend(Test)).settings(Defaults.itSettings: _ *)

Project.inConfig(Test)(baseAssemblySettings)

test in (Test, assembly) := {}

assemblyOption in (Test, assembly) := (assemblyOption in (Test, assembly)).value.copy(includeScala = false, includeDependency = true)

assemblyJarName in (Test, assembly) := s"${name.value}-test.jar"

fullClasspath in (Test, assembly) := {
  val cp = (fullClasspath in Test).value
  cp.filter{ file => (file.data.name contains "classes") || (file.data.name contains "test-classes")}  ++  (fullClasspath in Runtime).value
}

libraryDependencies ++= Seq(
  ...
  "com.typesafe.play" %% "play-json" % "2.3.10" % "test" excludeAll ExclusionRule(organization = "joda-time"),
  ...
)

...

當我使用sbt test:assembly組裝胖子罐子時，會產生胖子罐子project-test.jar ，但是play-json依賴項沒有打包在其中：

$ jar tf /path/to/project-test.jar | grep play
$

但是，如果我從play-json dep中刪除了"test"配置（即"com.typesafe.play" %% "play-json" % "2.3.10" excludeAll ExclusionRule(organization = "joda-time") ）） ，我可以看到它包含在其中：

$ jar tf /path/to/project-test.jar | grep play
...
play/libs/Json.class
...
$

我在做錯什么和/或錯過任何事情嗎？ 我的目標是將play-json庫僅包含在test:assembly jar中，而不包括assembly jar中

Answer 1

我在上面發布的原始build.sbt摘錄中遺漏了關鍵部分，事實證明這是build.sbt的原因：

fullClasspath in (Test, assembly) := {
  val cp = (fullClasspath in Test).value
  cp.filter{ file => (file.data.name contains "classes") || (file.data.name contains "test-classes")}  ++  (fullClasspath in Runtime).value
}

該代碼塊實際上是從測試類路徑中過濾掉dep的。 我們將其包括在內以避免痛苦的合並沖突。 我通過添加邏輯以包含所需的play-json dep來解決此問題：

fullClasspath in (Test, assembly) := {
  val cp = (fullClasspath in Test).value
  cp.filter{ file =>
    (file.data.name contains "classes") ||
    (file.data.name contains "test-classes") ||
    // sorta hacky
    (file.data.name contains "play")
  }  ++  (fullClasspath in Runtime).value
}
