访问 sbt 子项目的 managedClasspath

Question

我正在将 sbt 0.7.x 构建脚本转换为 sbt 0.11.2。我正在编写一个任务来从子项目中收集各种 JAR。在旧版本中，部分任务执行以下操作：

deployedProjects.foreach {
  p: BasicScalaProject =>
    p.managedClasspath(config("compile")) --- p.managedClasspath(config("provided"))
    // etc
}

如何在 sbt 0.11 中做同样的事情？

更新添加：

特别是：

• 如何编写依赖于设置/任务列表的任务？例如，我将如何编写一个依赖于子项目列表中所有 managedClasspaths 的任务（而不将其全部捆绑到一个元组中）。
• 是否有特定范围来获取标记为“已提供”或未标记为“已提供”的托管 jar？

在 sbt 0.11.x 中有任务 managedClasspath:

> inspect managed-classpath
[info] Task: scala.collection.Seq[sbt.Attributed[java.io.File]]
[info] Description:
[info]  The classpath consisting of external, managed library dependencies.
[info] Provided by:
[info]  {file:/Users/heiko/tmp/test/}default-f3fb6c/compile:managed-classpath
[info] Dependencies:
[info]  compile:classpath-configuration
[info]  compile:classpath-types
[info]  compile:update
[info] Reverse dependencies:
[info]  compile:external-dependency-classpath
[info] Delegates:
[info]  compile:managed-classpath
[info]  *:managed-classpath
[info]  {.}/compile:managed-classpath
[info]  {.}/*:managed-classpath
[info]  */compile:managed-classpath
[info]  */*:managed-classpath
[info] Related:
[info]  test:managed-classpath
[info]  runtime:managed-classpath

查看委托，您会发现您可以将此任务范围限定为各种配置，例如编译：

> show compile:managed-classpath
[info] Updating {file:/Users/heiko/tmp/test/}default-f3fb6c...
[info] Resolving org.scala-lang#scala-library;2.9.1 ...
