title: object typesafe is not a member of package
body: <p>I am currently trying to build and deploy a simple scala application on heroku. I am following the tutorial on the heroku website for Scala: <a href="https://devcenter.heroku.com/articles/getting-started-with-scala" rel="nofollow noreferrer">https://devcenter.heroku.com/articles/getting-started-with-scala</a></p>
  
  <p>However I keep getting the following error when I execute <strong>sbt clean compile stage</strong>:
  <img src="https://i.stack.imgur.com/la2xp.png" alt="Screenshot error"></p>
  
  <p>My build.sbt file is as follows:</p>
  
  <pre><code>import com.typesafe.startscript.StartScriptPlugin
  
  seq(StartScriptPlugin.startScriptForClassesSettings: _*)
  
  name := "hello"
  
  version := "1.0"
  
  scalaVersion := "2.9.2"
  
  resolvers += "twitter-repo" at "http://maven.twttr.com"
  
  libraryDependencies ++= Seq("com.twitter" % "finagle-core" % "1.9.0", "com.twitter" % "finagle-http" % "1.9.0")
  </code></pre>
  
  <p>I have a project/build.sbt file as well as follows:</p>
  
  <pre><code>resolvers += "twitter-repo" at "http://maven.twttr.com"
  
  libraryDependencies ++= Seq("com.twitter" % "finagle-core" % "1.9.0", "com.twitter" % "finagle-http" % "1.9.0")
  </code></pre>
  
  <p>My project/build.properties file is as follows:</p>
  
  <pre><code>sbt.version=0.12.0
  </code></pre>
  
  <p>Anyone know what I am doing wrong?, help greatly appreciated</p>
