javaOptions in Universal doesn't have effect in custom plugin

[prophe05]

I try to create custom plugin, that use Universal plugin,
I want to set javaOptions in Universal like:

override def requires = UniversalPlugin

override def projectSettings: Seq[Setting[_]] = Seq(
  javaOptions in Universal := {
      val log = sLog.value
      log.warn("!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!")
      Seq(
        "-Dconfig.file=./conf/production.conf"
      , "-Dlogback.configurationFile=./conf/logback.xml"
      )
    }
)

but there is no effect.

Expected behaviour

.ini file should be generated
log message should appear

Actual behaviour

no result

I think an output of sbt inspect universal:javaOptions could be helpful

Could you show please how do you enable plugins in your project? What command did you run?

[prophe05]

This is simplified version of my plugin

import sbt._
import Keys._
import com.typesafe.sbt.SbtNativePackager._
import com.typesafe.sbt.packager.universal.UniversalPlugin

/** sets the build environment */
object BuildEnvPlugin extends AutoPlugin {

  // make sure it triggers automatically
  override def trigger = AllRequirements
  override def requires = UniversalPlugin

  override def projectSettings: Seq[Setting[_]] = Seq(
    javaOptions in Universal := {
      val log = sLog.value
      log.warn("!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!")
      Seq(
        "-Dconfig.file=./conf/application.conf"
      , "-Dlogback.configurationFile=./conf/logback.xml"
      )
    }
  }
}

This is a project where I use it:

enablePlugins(JavaAppPackaging, DockerPlugin, BuildEnvPlugin)

lazy val root = project
	.in(file("."))
	.settings(
		name := appName
	,	version := appVersion
	,	libraryDependencies ++= appDependencies
	,	fork in run := true
	)

override def requires = JavaAppPackaging && UniversalPlugin

solved the problem
