Getting the current sbt plugin cross version

Question

I'm trying to cross-build an sbt plugin between 0.13 and 1.1. To accomplish this I need to use different libraryDependencies for the different builds, but I can't find a way to access the current build's target sbt version.

Back when the cross compilation was in a plugin there was CrossBuilding.pluginSbtVersion but I can't find anything similar anymore.

sbtVersion.value always gives me 0.13.16
(sbtVersion in sbtPlugin) likewise
crossVersion always gives me Binary
scalaBinaryVersion always gives me 2.10

How can I do this?

you can use the following code:

libraryDependencies ++= {
  sbtBinaryVersion.value match {
    case "0.13" => Seq(...)
    case "1.0" => Seq(...)
  }
}

make sure to run your sbt commands with ^, to run command on all sbt versions, ie:

sbt "^compile"

For some reason that gives `0.13` all the time as well :/ – tjarvstrand Apr 16 '18 at 09:00
have you defined `crossSbtVersions := Vector("0.13.17", "1.1.4")` ? – lev Apr 16 '18 at 09:01
Yes. I found out how to solve my issue though. See my answer. Thanks anyway! – tjarvstrand Apr 16 '18 at 09:34

It turns out the solution was present in sbt's output all along:

[info] Setting `sbtVersion in pluginCrossBuild` to 1.1.2

I just had to use (sbtBinaryVersion in pluginCrossBuild).value
