title: IntelliJ IDEA 13: new Scala SBT project hasn't src directory structure generated
body: <p>I followed the getting start video on Jetbrains website to setup IntelliJ IDEA 13.1 Community Edition to work with Scala. Scala plugin v0.36.431 had been installed. While I created a new Scala SBT project with wizard, there was no <code>src/</code> directory structure generated in the project. Only two sbt files were generated:</p>
  
  <pre><code>scala-course/
  ├── build.sbt
  └── project
      └── plugins.sbt
  </code></pre>
  
  <p>From the video and other document I know that there should be a <code>src/</code> directory structure, including <code>src/main/scala</code>, <code>src/test/scala</code>, etc. sbt uses the same directory structure as Maven for source files by default.</p>
  
  <p>I can create those folders manually and mark it as source root. However it is trivial. So my question is: Why IntelliJ IDEA new project wizard doesn't generate the directory structure as said in document? Was I doing something wrong? I checked the preferences and couldn't find anything that seems related.</p>
