Can't resolve docker related sbt tags - scala

Question

I'm trying to add sbt-docker to my sbt build of my play website but I'm running into an issue. For some reason none of the docker related stuff on the bottom can resolve.
project/plugins.sbt
logLevel := Level.Warn
resolvers ++= Seq(
"Typesafe repository" at "http://repo.typesafe.com/typesafe/releases/"
)
addSbtPlugin("com.typesafe.play" % "sbt-plugin" % "2.5.9")
build.sbt
name := "personal_site"
version := "1.1"
lazy val `personal_site` = (project in file(".")).enablePlugins(PlayScala,DockerPlugin)
scalaVersion := "2.11.7"
libraryDependencies ++= Seq( jdbc , cache , ws , specs2 % Test )
unmanagedResourceDirectories in Test <+= baseDirectory ( _ /"target/web/public/test" )
resolvers += "scalaz-bintray" at "https://dl.bintray.com/scalaz/releases"
dockerfile in docker := {
val targetDir = "/usr/src"
new Dockerfile {
from("flurdy/activator")
//More goes here
}
}
imageNames in docker := Seq(
// Sets the latest tag
ImageName(s"${name.value}:latest"),
// Sets a name with a tag that contains the project version
ImageName(
namespace = None,
repository = name.value,
tag = Some("v" + version.value)
)
)
Here's an image of what it looks like in IntelliJ
I've also tried adding addSbtPlugin("se.marcuslonnberg" % "sbt-docker" % "1.4.0") to my project/plugins.sbt but I get this error about DockerPlugin being imported twice.
~/Sync/Projects/Programming/Personal_Site (master ✘)✹ ᐅ sbt clean
[info] Loading project definition from /home/ryan/Sync/Projects/Programming/Personal_Site/project
/home/ryan/Sync/Projects/Programming/Personal_Site/build.sbt:5: error: reference to DockerPlugin is ambiguous;
it is imported twice in the same scope by
import _root_.sbtdocker.DockerPlugin
and import _root_.com.typesafe.sbt.packager.docker.DockerPlugin
lazy val `personal_site` = (project in file(".")).enablePlugins(PlayScala,DockerPlugin)

Answer 1

Try changing your build.sbt config to this.
lazy val root = (project in file(".")).enablePlugins(sbtdocker.DockerPlugin, PlayScala)
It removes the ambiguity by using the full name to DockerPlugin, since sbt-native-packager uses the same name for its Docker plugin I believe.
Maybe worth raising a Github issue with the author's repo so they can document it in the project docs.
