SBT, include entire external directory (with the dir itself) in jar built

问题

I need to include entire static directory from external location in my SBT-generated JAR file (with optional folder renaming).

Adding it's path to unmanagedResourceDirectories adds its content only, not the entire directory which results in static content in the JAR root. I was playing with mappings of various sorts but with no luck.

Does anyone had similar use-case and could point me to the right direction on how to do that?

I can't modify the process that generates the static dir and can't use it's parent as it has other files/dirs I don't want inside.

回答1:

Ok, I sorted it out with a little hint I got on sbt's gitter channel. So mappings is what I needed:

mappings in (Compile, packageBin) := {
  val statics = contentOf(baseDirectory.value / "static").map {
    case (file, dest) => file -> s"webapp/$dest"
  }
  (mappings in (Compile, packageBin)).value ++ statics
}

This will take all the content from static directory and place it in the webapp directory of the resulting JAR file
