Arcadia unified Scalastyle configuration

We use Scalastyle in conjunction with our build systems to establish and maintain unified and automated style conformation.

Integration

Our project templates should already have integration in place, but in case not, here's a starting point.

SBT via scalastyle-sbt-plugin

(scalastyleConfigUrl in Compile) := Some(
  url("https://raw.githubusercontent.com/arcadia/scalastyle/master/scalastyle-config.xml")
)

lazy val testScalastyle = taskKey[Unit]("testScalastyle")
(scalastyleConfigUrl in Test) := Some(
  url("https://raw.githubusercontent.com/arcadia/scalastyle/master/scalastyle-config.xml")
)
(scalastyleFailOnError in Test) := false
(scalastyleFailOnWarning in Test) := false
testScalastyle := scalastyle.in(Test).toTask("").value
(test in Test) := ((test in Test) dependsOn testScalastyle).value

lazy val symlinkScalaStyle = taskKey[Unit]("Creates a symbolic link that enables ScalaStyle within IntelliJ")
symlinkScalaStyle := {
    val symTarget = (target.value / scalastyleConfigUrlCacheFile.value).toString
    val symFile = (baseDirectory.value / s"project/${scalastyleConfig.value}").toString
    val command: Seq[String] = "ln" :: "-fs" :: symTarget :: symFile :: Nil
    Process(command) !
}
