title: Could not open no_buildscript class cache for script
body: <p>When I executed a <code>gradle</code> command (Cygwin environment):</p>
  
  <pre><code>gradle cleanidea eclipse
  </code></pre>
  
  <p>It went wrong with this error log:</p>
  
  <pre><code>Could not open no_buildscript class cache for script 'jar:file:/D:/Program%20Files/gradle-2.5/lib/gradle-core-2.5.jar!/org/gradle/initialization/buildsrc/defaultBuildSourceScript.txt' (C:\Users\mingle\.gradle\caches\2.5\scripts\defaultBuildSourceScript_ehlybs1v0v6kbup5qmtxh65v\DefaultScript\no_buildscript).
  
  Signature Parse error: Expected Field Type Signature
          Remaining input: +Ljava/util/Spliterator$OfInt;
  </code></pre>
  
  <p>I tried to run with <code>--info</code> or <code>--debug</code> option to get more log output.
  This is the exception thrown:</p>
