лифт не строится с помощью sbt?

Я выполняю шаги для sbt 0.10 на вики-странице Assembla Lift и получаю следующую ошибку:

[warn] ::::::::::::::::::::::::::::::::::::::::::::::
[warn] :: UNRESOLVED DEPENDENCIES ::
[warn] ::::::::::::::::::::::::::::::::::::::::::::::
[warn] :: com.github.mpeltonen#sbt-idea_2.8.1;0.10.0-SNAPSHOT: not found
[warn] :: com.github.siasia#xsbt-web-plugin_2.8.1;0.10.1: not found
[warn] ::::::::::::::::::::::::::::::::::::::::::::::
[info]

, вероятно, потому что обеих страниц:

http://siasia.github.com/maven2

и

http://mpeltonen.github.com/maven/

не существует?

Мой build.sbt :

name := "MyWeb"

scalaVersion := "2.9.0"

seq(WebPlugin.webSettings: _*)

resolvers += "Web plugin repo" at "http://siasia.github.com/maven2"
resolvers += "Web plugin repo2" at "http://mpeltonen.github.com/maven/"


libraryDependencies ++= {

  val liftVersion = "2.4-M1"

  Seq(
    "net.liftweb" %% "lift-webkit" % liftVersion % "compile->default",
    "net.liftweb" %% "lift-mapper" % liftVersion % "compile->default",
    "net.liftweb" %% "lift-wizard" % liftVersion % "compile->default"
  )

} 

libraryDependencies ++= Seq(
  "junit" % "junit" % "4.5" % "test->default",
  "org.mortbay.jetty" % "jetty" % "6.1.22" % "jetty",
  "javax.servlet" % "servlet-api" % "2.5" % "provided->default",
  "com.h2database" % "h2" % "1.2.138",
  "ch.qos.logback" % "logback-classic" % "0.9.26" % "compile->default"
)

и plugins / build.sbt:

resolvers += "Web plugin repo" at "http://siasia.github.com/maven2"

libraryDependencies <+= sbtVersion("com.github.siasia" %% "xsbt-web-plugin" % _)

Что я делаю не так?
