Is it possible to specify the coursier cache location from the sbt command line?

The code suggests this is possible, but I haven’t been able to make it work. I’ve tried

sbt -Dcoursier.cache=.coursier compile

sbt -Dcoursier.cache=/absolute/path/to/.coursier compile

sbt -Dcoursier.cache=/absolute/path/to/without/period/coursier compile

sbt -Dcoursier.cache="/lets/try/quotation/marks/coursier" compile

But the system always uses ~/.coursier instead.

Setting the coursier cache location via export (as per the README, export COURSIER_CACHE="$(pwd)/.coursier-cache") works as expected. Is there a reason this doesn’t?

Coursier uses the COURSIER_CACHE environment variable to specify the cache. So:

export COURSIER_CACHE=some/dir sbt clean compile

@drewctaylor SBT actually uses different Java system property: -Dsbt.coursier.home. Look here https://github.com/sbt/sbt/blob/v1.3.1/main/src/main/scala/sbt/coursierint/LMCoursier.scala#L40-L44

  def defaultCacheLocation: File =
    sys.props.get("sbt.coursier.home") match {
      case Some(home) => new File(home).getAbsoluteFile / "cache"
      case _          => CoursierDependencyResolution.defaultCacheLocation
    }

-Dcoursier.cache somehow doesn’t have any effect on SBT in my case too.
