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，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 
} 

我该怎么做sbt 0.11中的等价物？

更新补充：

特别是：

• 我如何编写依赖的设置/任务列表中的任务？例如，我将如何编写一个依赖于子项目列表中的所有managedClasspath的任务（没有将其全部捆绑到一个元组中）。
• 是否有一个特定的范围来获取已标记或未标记为“已提供”的托管瓶子？

在SBT 0.11.x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 

纵观代表你看，你可以范围这个任务交给各种配置，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 ... 
[info] Done updating.
