SBT 交叉构建 - 为不同的 Scala 版本选择不同的库版本 [英] SBT cross building - choosing a different library version for different scala version

问题描述

是否可以将 SBT 配置为在交叉构建时使用完全不同的库版本，具体取决于构建项目所使用的 Scala 版本?

例如:

• 使用 Scala 构建时 2.9.2 我想使用 "org.scalatest" % "scalatest_2.9.2" % "2.0.M5" % "test"
• 使用 scala 2.10.0 构建时，我想使用 "org.scalatest" % "scalatest_2.10.0-RC5" % "2.0.M5-B1" % "test"

解决方案

这样的事情应该可行:

libraryDependencies <+= scalaVersion(scalatestDependency(_))def scalatestDependency(scalaVersion: String) = scalaVersion match {情况2.9.2"=>"org.scalatest" % "scalatest_2.9.2" % "2.0.M5" % "test"情况2.10.0"=>org.scalatest"%scalatest_2.10.0-RC5"%2.0.M5-B1"%测试"}

我假设您实际上是说库版本应该是相反的?:-)

您可以在 ScalaMock 2 构建中看到此主题的变体.>

Is it possible to configure SBT to use a completely different library version when cross building, depending on the scala version the project is being built with?

For example:

• When building with Scala 2.9.2 I want to use "org.scalatest" % "scalatest_2.9.2" % "2.0.M5" % "test"
• When building with scala 2.10.0 I want to use "org.scalatest" % "scalatest_2.10.0-RC5" % "2.0.M5-B1" % "test"

解决方案

Something like this should work:

libraryDependencies <+= scalaVersion(scalatestDependency(_))

def scalatestDependency(scalaVersion: String) = scalaVersion match {
  case "2.9.2" => "org.scalatest" % "scalatest_2.9.2" % "2.0.M5" % "test"
  case "2.10.0" => "org.scalatest" % "scalatest_2.10.0-RC5" % "2.0.M5-B1" % "test"
}

I assumed that you actually meant that the library versions should be the other way around? :-)

You can see variations on this theme in the ScalaMock 2 build.
