sbt - 如何将自定义资源目录添加到测试类路径而不复制其中的文件？

Question

当我运行测试时，我的特殊资源目录 special-resources 的内容被复制到 target/classes目录。我有这样的事情

unmanagedResourceDirectories in Compile += baseDirectory.value / "special-resources",

但是我不想将这些资源复制到 target目录，但我希望它们位于 fork 的 java 进程的类路径上(例如用于测试)。

我试过使用

unmanagedClasspath in Compile += baseDirectory.value / "special-resources",

但是资源不可用。

如何将资源目录添加到类路径而不必复制文件？或者，我如何设置 sbt 以不将资源复制到目标目录？

Answer 1

有内容的special-resources包含在测试类路径中的目录和 runMain任务，请执行以下操作:

unmanagedClasspath in Test += baseDirectory.value / "special-resources"

unmanagedClasspath in (Compile, runMain) += baseDirectory.value / "special-resources"

使用 show 检查设置是否正确:

> show test:unmanagedClasspath
[info] List(Attributed(C:\dev\sandbox\runtime-assembly\special-resources))

通过以下 Specs2 测试，我确信设置运行良好:

import org.specs2.mutable._

class HelloWorldSpec extends Specification {

  "Hello world" should {
    "find the file on classpath" in {
      val text = io.Source.fromInputStream(getClass.getResourceAsStream("hello.txt")).mkString
      text must have size(11)
    }
  }
}

hello.txt在 special-resources带有 hello world 的目录里面的字符串。

和 build.sbt :

unmanagedClasspath in Test += baseDirectory.value / "special-resources"

libraryDependencies += "org.specs2" %% "specs2" % "2.4" % "test"

fork in Test := true
