Same file can't be packaged multiple times

See original GitHub issue

On sbt 0.13.8 (haven’t tested other versions), if I do:

mappings ++= Seq(
  foo -> "foo1",
  foo -> "foo2"
)

Only foo2 ends up in the packaged jar. Both should be packaged.

This bug still exists in sbt 1.2.0:

mappings in (Compile, packageBin) := {
  val readme = baseDirectory.value / "README.txt"
  Seq(
    readme -> "README1.txt",
    readme -> "README2.txt"
  )
}
lazy val extract = taskKey[Unit]("extract jar file")
extract := {
  IO.unzip((packageBin in Compile).value, target.value / "extracted")
}

$ sbt extract
