How to add sbteclipse plugin to SBT 0.10.x

Question

I want to view the source code of akka, and it seems using the 0.7.x version of sbt.
I transform the project configuration to the 0.10.x version. When i add sbteclipse in the libraray-dependencies and run eclipse create-src to generate eclipse project, it told that eclipse is not a command. Here is my Build.scala. The sbteclipse_2.8.1.jar is actually exists when i using library-dependencies to list the library

I was taking a silly mistake before. The plugin definition should be declared in project/plugins/build.sbt file, not as library dependency in yourproject/build.sbt

import sbt._

  val buildSettings = Defaults.defaultSettings ++ Seq(
    scalaVersion := buildScalaVersion,

    resolvers := Repos)

I wasn't sure from your questions whether you were using 0.7.x or 0.10.x, but here's an answer for 0.10.x

Put the following in your ~/.sbt/plugins/build.sbt file

resolvers += {
  val typesafeRepoUrl = new java.net.URL("http://repo.typesafe.com/typesafe/releases")
  val pattern = Patterns(false, "[organisation]/[module]/[sbtversion]/[revision]/[type]s/[module](-[classifier])-[revision].[ext]")
  Resolver.url("Typesafe Repository", typesafeRepoUrl)(pattern)
}

libraryDependencies <<= (libraryDependencies, sbtVersion) { (deps, version) => 
  deps :+ ("com.typesafe.sbteclipse" %% "sbteclipse" % "1.1" extra("sbtversion" -> version))
}
