Accessing managedClasspath of sbt subprojects - sbt

Question

I'm converting an sbt 0.7.x build script to sbt 0.11.2. I'm writing a task to collect various JARs together from subprojects. In the old build, part of the task does the following:
deployedProjects.foreach {
p: BasicScalaProject =>
p.managedClasspath(config("compile")) --- p.managedClasspath(config("provided"))
// etc
}
How can I do the equivalent in sbt 0.11?
Updated to add:
In particular:
How can I write a task that depends on a list of settings/tasks? For example, how would I write a task that depends on all the managedClasspaths from a List of subprojects (without bundling it all into a tuple).
Is there a particular scope for getting the managed jars that are or are not marked as "provided"?

In sbt 0.11.x there is the task 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] runtime:managed-classpath
Looking at the delegates you see that you can scope this task to various configurations, e.g. compile:
> show compile:managed-classpath
