sbtでversionが-SNAPSHOTの場合にpublishToをsnapshotに切り替える方法

gistfile1.scala

import sbt._

class MyProject(info: ProjectInfo) extends DefaultProject(info) {

  override def managedStyle = ManagedStyle.Maven

  // publishing
  lazy val publishTo = if (version.toString.endsWith("-SNAPSHOT")){
    println("Selected Snapshot")
    Resolver.sftp("Tricreo Repo", "maven.tricreo.jp", "/var/www/maven.tricreo.jp/snapshot")
  }else{
    println("Selected Release")
    Resolver.sftp("Tricreo Repo", "maven.tricreo.jp", "/var/www/maven.tricreo.jp/release")
  }

}
