Scala playframework为什么不导入库

我正试着用它。但我在尝试导入库时被卡住了

import org.scalatestplus.play._

我在build.sbt中添加了此依赖项

  libraryDependencies += "org.scalatestplus" % "play_2.10" % "1.2.0"

它不会更新依赖项列表

如果我尝试激活器更新，我会成功

$ activator update

  [info] Done updating.

即使在那之后，我也不能

   import org.scalatestplus.play._

这是我的build.sbt：-

  lazy val root = (project in file(".")).enablePlugins(PlayScala)

  scalaVersion := "2.11.5"

  libraryDependencies += "org.scalatestplus" % "play_2.11" % "1.2.0" % "test"

 libraryDependencies ++= Seq(
 jdbc,
 anorm,
 cache,
 ws,
 "com.typesafe.slick" % "slick_2.11" % "3.0.0-M1",
 "com.typesafe.play" % "play-slick_2.11" % "0.8.1",
 "org.slf4j" % "slf4j-nop" % "1.6.4",
 "org.postgresql" % "postgresql" % "9.4-1200-jdbc41",
 "org.scalatest" % "scalatest_2.11" % "2.2.4" % "test",
 "org.mockito" % "mockito-core" % "1.10.19" % "test",
 "com.h2database" % "h2" % "1.3.166",
 "org.xerial" % "sqlite-jdbc" % "3.6.20",
 "org.scala-lang" % "scala-actors" % "2.11.0"
 )

怎么了？如何导入org.scalatestplus.play.\u

使用测试代码更新更多信息

我发现scalatestplus游戏中存在问题。检查@

我在使用时为我工作

  "org.scalatestplus" %% "play" % "1.2.0" % "test"

感谢所有支持我的人

单独添加测试依赖项有什么具体原因吗？您想在哪里执行导入？REPL、src/main或src/test？实际抛出的错误是什么？当您通过test:compile编译测试时会发生什么情况？@singhakash我在Seq中尝试过。。而在这两种方式之外，结果是一样的。就在问问题的时候，它仍然在外面。@JustinPihony我正在一个play2.0web应用程序中尝试。所以它位于app/test/directory中

  "org.scalatestplus" %% "play" % "1.2.0" % "test"
