sbt 无法执行 JUnit 测试

Question

我正在尝试执行 JUnit 测试

sbt 测试

sbt 清洁测试

测试失败并出现错误：

我的 build.sbt 文件内容

name := "sbt junit test project"
version := "1.0"
scalaVersion := "2.10.5"
libraryDependencies += "com.novocode" % "junit-interface" % "0.8" % "test->default"
libraryDependencies += "junit" % "junit" % "4.12" % Test
EclipseKeys.withSource := true

文件 %USERDIR%.sbt\0.13\plugins\build.sbt 看起来像

resolvers += Classpaths.typesafeResolver
addSbtPlugin("com.typesafe.sbteclipse" % "sbteclipse-plugin" % "4.0.0")

Answer 1

把 build.sbt 放到项目根目录下，否则sbt clean 看不到 build.sbt 和下载依赖。最初 build.sbt 位于<project root>\project\ 文件夹中
