Re: [sbt] Custom task to be called by sub-projects with sub-project scope

[Steven Yang]

Hi

Sorry I figured it out.
I have to use .settings() to override the taskKey in each sub-project.

Hi all

I have a basic multi-project build which had no problem building and executing built-in sub-project tasks independently.

Now I need to write a small task which need to be executed by each sub-project independently and the task requires each sub-project's independent environment.

For example I have the following:

lazy val testTask = TaskKey[Unit]("test", "This is a test")

testTask in subProj1 := {

  println((name in subProj1).value + " : " + (baseDirectory in subProj1).value / "version.sbt")
}
For this I am basically hard-coding the sub-project into the task and am able to get name and baseDirectory of the sub-project, but this means I have to write one for each sub-project.
This is obviously not good.
I wish to define this once in root and to be used in each of my sub-project.
Can some one shine some light one me? or point me to some resource?

Thanks
