How to use sbt-scalabuff plugin with sbt 0.13? - scala

Question

I am trying to use sbt-scalabuff plugin, but sbt keeps complaining that the plugin cannot be found.
The plugin documentation does not state out a resolver url, either. Is the plugin deprecated or my Scala version is not supported?
Details:
com.github.sbt:sbt-scalabuff:0.2 (sbtVersion=0.13, scalaVersion=2.10)
Here is my plugins.sbt:
libraryDependencies += "net.sandrogrzicic" %% "scalabuff-runtime" % "1.3.6"
addSbtPlugin("com.github.sbt" %% "sbt-scalabuff" % "0.2")
Here is part of the stack trace:
sbt.ResolveException: unresolved dependency: com.github.sbt#sbt-scalabuff;0.2: not found

The sbt-scalabuff plugin does not have the plugin jar published to any known repository sbt could use for your configuration - sbtVersion=0.13 and scalaVersion=2.10.
I also doubt the plugin supports sbt 0.13 (few attempts of mine failed miserably when I compiled the plugin myself to use the version).
It seems that your only options are to downgrade sbt to 0.12.4 or migrate the plugin to 0.13.
Since the plugin has been published to the Resolver.sbtPluginRepo("releases") repository, i.e. http://repo.scala-sbt.org/scalasbt/sbt-plugin-releases as http://dl.bintray.com/sbt/sbt-plugin-releases/com.github.sbt/sbt-scalabuff/scala_2.10/sbt_0.12/ you will have to use the version of sbt.
Use the following in project/sbt-scalabuff.sbt:
addSbtPlugin("com.github.sbt" %% "sbt-scalabuff" % "0.2")
You should then specify the version of sbt in project/build.properties as follows:
sbt.version=0.12.4
or just use sbt-launch 0.12.4.
When in sbt console, you can use the scalabuff task or the settings: scalabuff-version, scalabuff-main and scalabuff-args.

See the scalabuff.ScalaBuffPlugin object in the GitHub repository.
I also had to change the build object (as described in the Usage section) to set up a project with the plugin to import sbt._:
import sbt._
import scalabuff.ScalaBuffPlugin._
object build extends Build {
lazy val root = Project(
"main",
file("."),
settings = Defaults.defaultSettings ++ scalabuffSettings
).configs(ScalaBuff)
}
