SBT Native Packager - Auto Plugins

AutoPlugins.scala

// API proposal # 1
lazy val root = project(file(".")
  .enablePlugins(SbtNativePackager, JavaServerArchetype)
  .settings(
    "maintainer" in Debian := "Your Name <your.name@your-company.com"
  )
)

// Implementation may look like
object SbtNativePackager extends AutoPlugin
 with linux.LinuxPlugin with ... {
  
  object autoimport extends linux.Keys.autoimport with ...
  
  // projectSettings or buildSettings ?
  override lazy val buildSettings = linuxSettings ++ ...
}

// API proposal # 2
lazy val root = project(file(".")
  .enablePlugins(UniversalPackagingPlugin, NativeDebianPackagingPlugin, JavaServerArchetype)
  .settings(
    "maintainer" in Debian := "Your Name <your.name@your-company.com"
  )
)

// Implementation may look like
object UniversalPackagingPlugin extends AutoPlugin {
  
  object autoimport {
    
  }
  
  // projectSettings or buildSettings ?
  override lazy val buildSettings = Seq(...)
}

object WindowsPlugin extends AutoPlugin {
  
  override def requires = UniversalPackagingPlugin
  
  object autoimport {
    
  }
  
  // projectSettings or buildSettings ?
  override lazy val buildSettings = Seq(...)
}

IMHO the GenericToXYZ mappings should be handled by the respective plugin (Linux, Windows). If the archetypes require all these plugins, the mappings are always in place.
