scala - 如何从插件添加的libraryDependencies中删除依赖项？

Question

对于Play 2.3 Scala项目，我有一个非常经典的build.sbt，具有以下libraryDependencies设置:

libraryDependencies ++= Seq(
  "org.scalatestplus" % "play_2.10" % "1.1.0" % "test"
  "org.mockito" % "mockito-core" % "1.9.5" % "test"
)

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

PlayScala插件添加了 specs2依赖项，该依赖项会“污染”类路径，并在IDE中使良好的导入更加困难。

如何从 libraryDependencies中删除依赖项？

Answer 1

我通过将以下内容添加到Build.scala中来解决了类似的问题:

def excludeSpecs2(module: ModuleID): ModuleID =
  module.excludeAll(ExclusionRule(organization = "org.specs2"))

val main = Project(appName, file("."))
  .enablePlugins(play.PlayScala)
  .settings(libraryDependencies ~= (_.map(excludeSpecs2)))
