title: Why does IDEA report errors for build.sbt in a new sbt project?
body: <p>I'm running IntelliJ 13.1.5 community edition. I've got JDK, Scala, SBT installed. The JAVA_HOME, JDK_HOME, SCALA_HOME and SBT_HOME variables are set. If I create a new SBT project, after initial sbt refresh, I get this:</p>
  
  <p><img src="https://i.stack.imgur.com/Fy7LU.png" alt="intellij error"></p>
  
  <p>The thing compiles and runs fine, even if I add dependencies, but the file itself shows tonnes of errors. F4 settings show empty SBT module stuff:</p>

  <p>I then installed <a href="https://github.com/mpeltonen/sbt-idea" rel="noreferrer">https://github.com/mpeltonen/sbt-idea</a> and ran sbt gen-idea in the project folder. This created a bunch of files, and reloading the project, the reds in the sbt file went away.</p>
  
  <p>This is on my laptop. However, on my work machine, simply creating a new project works fine, and the sbt file isn't filled with red. Can't seem to figure out how that machine's different. Any pointers on how to resolve this annoying issue?</p>
