  <p>saw a similar bug on gradle forums but that one seems old and fixed
  <a href="https://issues.gradle.org/browse/GRADLE-2167" rel="noreferrer">https://issues.gradle.org/browse/GRADLE-2167</a></p>
  
  <p>I tried reducing my classpath, but no use, still same error. Damn windows!! the classpath added by gradle is too long with all those generated cache folder names. saw this post so wondering if there could be some config to make gatling work on windows with gradle
  <a href="https://discuss.gradle.org/t/filename-too-long-in-windows/9222" rel="noreferrer">https://discuss.gradle.org/t/filename-too-long-in-windows/9222</a>
  any gradle experts to the rescue plz</p>
