How to set up sbt-assembly to include jars with runtime scope?

How to set up sbt-assembly to include jars with runtime scope? What's the rationale for not doing it by default?

This is now being discussed under sbt/sbt-assembly#120.

sbt-assembly is intended to wire full classpath from Runtime configuration. And it's coded as follows:

fullClasspath in assembly <<= fullClasspath or (fullClasspath in Runtime),

For Spark, for whatever reason fullClasspath is wired, so that's likely interfering. The reason sbt-assembly included fullClasspath I think is now historical, so I might get rid of "fullClasspath or" part. As noted in the issue, the current workaround is likely:

fullClasspath in assembly := (fullClasspath in Runtime).value

FYI for those who learn sbt the above sbt-0.13+ format with := corresponds to the older pre-sbt-0.13 format with := as follows:

fullClasspath in assembly <<= (fullClasspath in Runtime)

My tests show that the plugin does include dependencies with runtime scope as evidenced with the following example.

project/plugins.sbt

addSbtPlugin("com.eed3si9n" % "sbt-assembly" % "0.11.2")

build.sbt

libraryDependencies += "ch.qos.logback" % "logback-classic" % "1.1.2" % "runtime"

assemblySettings

This is a sample session:
