Question

由于冲突/传递（elasticsearch / lucene / jackrabbit）依赖关系，我想在测试中拥有与正常运行应用程序时不同的库依赖项。我通过下面的设置解决了这个问题，但这需要使用-Dtest运行激活器，这将阻止我的应用程序在完成测试后正常运行。反过来，即只运行激活器，将运行我的应用程序，但不会运行我的测试。所以，不是很方便，我认为这可以做得更好（顺便说一下，我对sbt / scala很新）

name := """example"""

version := "0.1"

lazy val root = (project in file(".")).enablePlugins(PlayJava)

scalaVersion := "2.11.1"

// fork in Test := true

javaOptions in Test += "-Dconfig.file=conf/application.test.conf"

javaOptions in Test += "-Dlogger.file=conf/test-logger.xml"

// run activator -Dtest
if (sys.props.contains("test")) {
  Seq[Project.Setting[_]](  
    libraryDependencies ++= {
      Seq(

我没有一个设置，我可以真正测试这是否有效，但从我如何理解sbt依赖它应该：

依赖关系可以有一种称为配置的范围。通常，这用于定义仅测试依赖项：

"com.typesafe.akka" %  "akka-testkit_2.11" % "2.3.14" % "test"

但你也应该能够使用“compile”和“runtime”来定义编译时和运行时的依赖关系。

如果我使用不同版本的依赖项，那么sbt会给我一个警告。问题是，这将使用不同版本的依赖项来编译它，然后使用测试运行它。因此它将针对与编译时不同的版本运行。当然有库可以使用，特别是如果你运行的是用于编译的新版本。

如果你真的需要使用不同的依赖项编译你的应用程序两次并使用一个构建版本来运行而另一个版本用于测试，我担心，没有扩展sbt或类似的东西就没有解决方案。

您可以尝试制作两个模块，一个包含主代码，另一个用于测试，然后尝试交叉构建第一个模块的两个不同版本。 Sbt可以轻松地跨多个Scala版本进行交叉构建，但我不认为它可以为多个版本的库开箱即用。

谢谢@dth，你让我走上正轨。以下设置对我有用：

libraryDependencies ++= {
  Seq(
      javaJdbc,
      javaEbean,
      cache,
      javaWs,
      "org.webjars" %% "webjars-play" % "2.3.0-2",
      "org.webjars" % "bootstrap" % "3.3.6",
      "org.webjars" % "font-awesome" % "4.5.0",
      "be.objectify" %% "deadbolt-java" % "2.3.3",
      "org.apache.lucene" % "lucene-core" % "3.6.0" % "compile,test",
      "org.elasticsearch" % "elasticsearch" % "1.7.4" % "compile,runtime",
      "org.elasticsearch" % "elasticsearch" % "1.7.4"  % "test" exclude("org.apache.lucene", "lucene-core"),          
      "javax.jcr" % "jcr" % "2.0",
      "org.apache.jackrabbit" % "jackrabbit-core" % "2.11.2",
      "org.apache.jackrabbit" % "jackrabbit-jcr2dav" % "2.11.2",
      "org.apache.tika" % "tika-parsers" % "1.11",
      "org.apache.tika" % "tika-core" % "1.11",
      "commons-io" % "commons-io" % "2.4",
      "com.typesafe.akka" %  "akka-testkit_2.11" % "2.3.14" % "test"     
   )
}

sbt不同的库在测试中的依赖性比在普通模式下
