title: Intellij broken SBT, cannot create new projects
body: <p>I created a Scala play 2 project and it worked fine, but the IDE found all sorts of issues in build.sbt. These errors didn't seem to affect anything, but I tried to fix them anyways. In doing so, I appear to have broken Intellij entirely and would like to start over.</p>
  
  <p>I followed the instructions on <a href="https://www.jetbrains.com/help/idea/directories-used-by-intellij-idea-to-store-settings-caches-plugins-and-logs.html" rel="nofollow noreferrer">this page</a> and re-setup the IDE, but now I cannot even properly create a Scala project.</p>

  <p>I found that the issue appears to be with SBT, and I managed to find the error in ~/Library/Logs/IntelliJIdea2017.1/sbt.last.log. What appears to be happening is that SBT encounters this error and the project is never completely loaded, and Intellij wasn't designed to expect errors here.</p>
  
  <p>The error is</p>
  
  <pre><code>[info] Loading project definition from /Users/me/IdeaProjects/playtestagain/project
  java.lang.NoClassDefFoundError: sbt/TrackLevel
  </code></pre>
  
  <p>I cannot seem to find any information about this. I reinstalled SBT through homebrew and it didn't seem to do anything. </p>
