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? [英] How to add custom resource directory to test classpath without copying the files inside?
问题描述
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.我有这样的东西
When I run my tests, the contents of my special resources directory special-resources
are copied to the target/classes
directory. I have something like this
unmanagedResourceDirectories in Compile += baseDirectory.value / "special-resources",
但我不想将这些资源复制到 target
目录中,但我希望它们位于分叉的 Java 进程的类路径上(例如用于测试).
But I do not want to copy these resources into the target
directory, but I want them to be on the classpath of forked java processes (e.g. for testing).
我试过使用
unmanagedClasspath in Compile += baseDirectory.value / "special-resources",
但资源不可用.
如何在不复制文件的情况下将资源目录添加到类路径?或者,我如何设置 sbt 以不将资源复制到目标目录?
How can I add a resource directory to the classpath without having to copy the files? Or, alternatively, how can I setup sbt to not copy resources to the target directory?
推荐答案
将 special-resources
目录的内容包含在测试和 runMain
任务的类路径中,请执行以下操作:
To have the contents of the special-resources
directory included in the classpath for tests and runMain
task, do the following:
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:
Check that the setting is set properly with show
:
> 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:
With the following Specs2 tests I'm convinced the setup worked fine:
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
位于 special-resources
目录中,其中包含一个 hello world
字符串.
hello.txt
is in the special-resources
directory with a hello world
string inside.

和build.sbt

libraryDependencies += "org.specs2" %% "specs2" % "2.4" % "test"
fork in Test := true
