Setting (scalastyleConfig in Test) inside an AutoPlugin doesn't work

jawshooah commented 9 years ago

I'm trying to extract shared plugins and settings into a common set of AutoPlugins. Here's the plugin for Scalastyle:

package com.jawshooah.sbt

import sbt._
import sbt.Keys._
import sbt.plugins.JvmPlugin

import org.scalastyle.sbt.ScalastylePlugin
import org.scalastyle.sbt.ScalastylePlugin._

object ScalastylePluginSettings extends AutoPlugin {
  override def requires = JvmPlugin
  override def trigger = allRequirements

  /* ScalastylePlugin is not an AutoPlugin, so we manually add its settings here */
  override def projectSettings =
    ScalastylePlugin.projectSettings ++
    baseSettings ++
    Project.inConfig(Compile)(baseSettings) ++
    Project.inConfig(Test)(baseSettings)

  lazy val baseSettings = Seq(
    (scalastyleConfig in Compile) := sbtCommonDir.value / "scalastyle-config.xml",
    (scalastyleConfig in Test) := sbtCommonDir.value / "scalastyle-test-config.xml"
  )

  lazy val sbtCommonDir = baseDirectory { _ / "project" / "sbt-common" }
}

scalastyleConfig appears to be set correctly in Compile:

...but not in Test:

If I add the line:

(scalastyleConfig in scalastyle) := sbtCommonDir.value / "scalastyle-test-config.xml"

...it works. I assume this is related to the way scalastyleConfig in Test is initially set, but this is very counterintuitive, and I'm not sure if it has any other repercussions.

I've created an example repository at jawshooah/sbt-scalastyle-autoplugin-test to demonstrate how to reproduce this issue.

jawshooah commented 8 years ago

Note that the same problem appears to be present when setting scalastyleTarget in Test, except that additionally setting scalastyleTarget in scalastyle doesn't work here.

@matthewfarwell Any input on this?
