Question

I am implementing custom deploy Task in SBT and I need to copy all required jars to deployment folder.
I am able to get paths to all external dependencies using update TaskKey. Unfortunately updateReport does not include internal dependencies.
Here is my simple configuration

val deploy = TaskKey[Unit]("deploy","deploy")

lazy val projectA = Project(id=project-a,
settings=Project.defaultSettings)

lazy val projectB = Project(id=project-b,
settings=Project.defaultSettings) dependsOn(projectA)

lazy val projectC = Project(id=project-c,
settings=Project.defaultSettings, ++ Seq(deployTask)) dependsOn(projectB)

val deployTask = deploy <<= (update) map {(updateReport) =>
val externalDependency = updateReport.allFiles //paths to all external dependencies are available here
//project-a.jar and project-b.jar are not here
}

So, the question is how can I obtain absolute path to internal project dependencies i.e. project-a.jar, project-b.jar

If you set the exportJars property:

exportJars := true

then

exportedProducts in Compile

Should give you the path to the jar file for a project:

> show export-jars
[info] true
> show exported-products
[info] List(Attributed(/Users/luke/Work/myproject/server/target/scala-2.9.2/server_2.9.2-0.3-SNAPSHOT.jar))
