This adds two new tasks: fileInputs and watchTriggers, that will be used by sbt
both to fetch files within a task as well as to create watch sources for
continuous builds. In a subsequent commit, I will add a task for a
command that will traverse the task dependency graph to find all of the
input task dependency scopes. The idea is to make it possible to easily
and accurately specify the watch sources for a task. For example, we'd
be able to write something like:
val foo = taskKey[Unit]("print text file contents")
foo / fileInputs := baseDirectory.value ** "*.txt"
foo := {
(foo / fileInputs).value.all.foreach(f =>
println(s"$f:\n${new String(java.nio.Files.readAllBytes(f.toPath))}"))
}
If the user then runs `~foo`, then the task should trigger if the user
modifies any file with the "txt" extension in the project directory.
Today, the user would have to do something like:
val fooInputs = settingKey[Seq[Source]]("the input files for foo")
fooInputs := baseDirectory.value ** "*.txt"
val foo = taskKey[Unit]("print text file contents")
foo := {
fooInputs.value.all.foreach(f =>
println(s"$f:\n${new String(java.nio.Files.readAllBytes(f.toPath))}"))
}
watchSources ++= fooInputs.value
or even worse:
val foo = taskKey[Unit]("print text file contents")
foo := {
(baseDirectory.value ** "*.txt").all.foreach(f =>
println(s"$f:\n${new String(java.nio.Files.readAllBytes(f.toPath))}"))
}
watchSources ++= baseDirectory.value ** "*.txt"
which makes it possible for the watchSources and the task sources to get
out of sync.
For consistency, I also renamed the `outputs` key `fileOutputs`.
