Howto create a .jar including both sources (.java and .scala) and classes with sbt?

Question

I would like sbt package or any variant to produce a '.jar' from my project that would include also the sources ('.java' and '.scala' files).

This would be a mix of packageBin and packageSrc.

I did not:

• find any task that would do this?
• find how to adapt package task
• nor define a new task of mine to achieve this

Thanks for any hint.

Answer 1

Looking at the documentation, you should probably add stuff to the mappings key in the packageBin scope. The following seems to work for me:

mappings in (Compile, packageBin) ++= (mappings in (Compile, packageSrc)).value

Answer 2

Here's how to setup a standalone task for creating an artifact with binaries and sources, leaving packageBin and packageSrc unaffected:

val packageBinSrc = taskKey[File]("Produces an artifact containing both binaries and sources.")

artifactClassifier in packageBinSrc := Some("binsrc")
inConfig(Compile) {
  import Defaults._
  packageTaskSettings(packageBinSrc, concatMappings(packageBinMappings, packageSrcMappings))
}

Optionally, if you fancy, you can redefine package to use packageBinSrc:

Keys.`package` := (packageBinSrc in Compile).value
