Possible to run multiple packaging tasks?

[Sciss]

Is it possible in a Build.scala to somehow invoke assembly multiple times?

I wish to generate platform specific jars, e.g. target/MyProject-Mac.jar, target/MyProject-Linux.jar, and target/MyProject-Windows.jar, each of which would require separate excludeFiles / excludeJars settings.

How would I do this?

I haven't tried it but this should work:

val Mac = config("mac") extend(Compile)
val Linux = config("linux") extend(Compile)
val Windows = config("windows") extend(Compile)

inConfig(Mac)(baseAssemblySettings ++ inTask(assembly)(Seq(
  excludedJars := Seq().classpath
))) ++
inConfig(Linux)(baseAssemblySettings ++ inTask(assembly)(Seq(
  excludedJars := Seq().classpath
))) ++
inConfig(Windows)(baseAssemblySettings ++ inTask(assembly)(Seq(
  excludedJars := Seq().classpath
)))

You can then run them as mac:assemby.
