title: Gradle project sync failed with no event log
body: <p>I have a libGDX project generated by the gdx-setup.jar tool, including core, android, desktop, and html modules. I hadn't touched any of the gradle files, and my build has worked fine for some weeks.</p>
  
  <p>This morning when I opened IntelliJ IDEA (build 135.1230), it offered to update the Scala plugin, so I accepted and restarted, before trying to open the project. My libGDX project doesn't use Scala at all: I have the plugin for other work. When I tried to open the project, I got the infamous "Gradle project sync failed. Basic functionality (e.g. editing, debugging) will not work properly" message. Clicking "Try again" thinks for a bit before showing the same message. The Event Log window contains no output, and the Messages window says:</p>
  
  <blockquote>
    <p>Error: (of class java.lang.String)</p>
  </blockquote>
  
  <p>The Scala plugin isn't the only thing that might have changed: I've rebooted the (Ubuntu) machine since the project last worked, so it's possible that some package updates might have only just had an effect.</p>
  
  <p>Following the advice of others, I've tried editing the root gradle.properties to change <code>org.gradle.configureondemand</code> to <code>false</code>, and that made no difference. I've tried performing "Build → Clean Project" and "Invalidate and Restart", with the same effect. I've also tried running <code>git clean -X</code> and reimporting the Gradle project into IDEA, but I just get a "Resolve error" dialog with the same message as above.</p>
  
  <p>Running a build command like</p>
  
  <pre><code>./gradlew android:assemble
  </code></pre>
  
  <p>from a shell still works fine: only IntelliJ IDEA has a problem.</p>
  
  <p>Even if you've never seen this particular problem, I'd appreciate any tips on where to start debugging it. The error message doesn't exactly give me a lot to go on.</p>
