title: Gradle 2.2.1 trying to use gradle-2.1-bin
body: <p>I'm developing multi-project java application in Eclipse 4.4.<br>
  Gradle 2.2.1 is installed in my local machine but gradle is trying to use gradle-2.1-bin.zip according to following stacktrace.
  Now I'm not using gradle-wrapper and <code>gradle -version</code> returns 2.2.1 in my bash. Anywhere else are there to investigate? </p>
  
  <pre><code>FAILURE: Build failed with an exception.
  
  * What went wrong:
  Execution failed for task ':myapp:compileJava'.
  &gt; java.lang.AssertionError: Null.
  
  * Try:
  Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output.
