sbt:添加对 Scalatest 库的依赖.在哪里? [英] sbt: Add dependency on scalatest library. Where?

问题描述

我使用 SBT 创建了一个 scala 项目，并使用 scalatest 编写了一些单元测试用例.但不知何故 sbt test 找不到 org.scalatest 包.

I created a scala project using SBT and wrote some unit test cases using scalatest. But somehow sbt test can't find the org.scalatest package.

这里是我的项目定义文件:

Here my project definition files:

• 源在 src/main/scala 对应的 src/test/scala

• build.sbt:

name := "MyProject"

version := "0.1"

scalaVersion := "2.9.2"

project/plugins.sbt:

addSbtPlugin("com.typesafe.sbteclipse" % "sbteclipse-plugin" % "2.1.0")

project/build.sbt:

libraryDependencies += "org.scalatest" %% "scalatest" % "1.8" % "test"

我使用的是 SBT 0.11.3.

I'm using SBT 0.11.3.

在控制台上使用 sbt compile 编译程序工作正常.此外，我在 ~/.ivy2 中找到了 scalatest jar，所以 SBT 一定已经下载了它.

Compiling the program using sbt compile on the console works fine. Furthermore I found the scalatest jar in ~/.ivy2, so SBT must have downloaded it.

但是当运行 sbt test 时，它说

But when running sbt test, it says

object scalatest is not a member of package org
[error] import org.scalatest.FlatSpec
...[many errors alike]

并且运行 sbt eclipse 会创建一个不包含 Scalatest jar 的 .classpath.

And running sbt eclipse creates a .classpath that doesn't contain the scalatest jar.

我是否必须在其他地方指定测试依赖项?我应该如何添加 Scalatest 库?

Do I have to specify the test dependencies somewhere else? How should I add the scalatest library?

推荐答案

将 libraryDependencies += "org.scalatest" %% "scalatest" % "1.8" % "test" 放入 build.sbt，而不是 project/build.sbt.

Place libraryDependencies += "org.scalatest" %% "scalatest" % "1.8" % "test" into build.sbt, not project/build.sbt.
