如何在 sbt-assembly jar 中包含测试依赖项？

Question

我无法将我的测试依赖项打包到我的测试程序集 jar 中。这是我的 build.sbt:

的摘录

...

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"),
  ...
)

...

当我 assemble 我的 fat jar 使用 sbt test:assembly 时，生成了 fat jar project-test.jar，但是 play-json 依赖项没有打包到：

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

但是，如果我从 play-json dep（即 "com.typesafe.play" %% "play-json" % "2.3.10" excludeAll ExclusionRule(organization = "joda-time")）中删除 "test" 配置，我可以看到它被包含在内：

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

我做错了什么吗and/or 遗漏了什么？我的目标是仅将 play-json 库包含在 test:assembly jar 而不是 assembly jar

Answer 1

我在上面发布的原始 build.sbt 摘录中遗漏了一个关键部分，结果证明这是问题的原因：

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
}

此代码块实质上是从测试类路径中过滤掉依赖项。我们包含它是为了避免痛苦的合并冲突。我通过添加逻辑以包含所需的 play-json dep 来修复此问题：

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
}
