`stagingDirectory` key conflicts with sbt 1.11.0

[mrdziuban]

I'm not really sure if this should be reported here or to sbt itself, but when upgrading to sbt 1.11.0 with a build.sbt that refers to the stagingDirectory I get this error:

/path/to-/my-project/build.sbt:564: error: reference to stagingDirectory is ambiguous;
it is imported twice in the same scope by
import _root_.com.typesafe.sbt.packager.universal.UniversalPlugin.autoImport._
and import _root_.sbt.Keys._
      val stagingDir = (Docker / stagingDirectory).value

It's simple to work around but I figured I'd report it anyway. For now I'm just importing sbt-native-packager's version as an alias, e.g.

import com.typesafe.sbt.packager.universal.UniversalPlugin.autoImport.{stagingDirectory => pkgStagingDirectory}
// or equivalently
import com.typesafe.sbt.packager.Keys.{stagingDirectory => pkgStagingDirectory}
