title: Android Studio: How do I find where Gradle has been installed?
body: <p>I have installed <code>Android Studio</code> but would like to use <code>Gradle</code> to build a simple "hello world" <code>Java</code> application that I have created outside of AS.</p>
  
  <p>I have added the <code>java plugin</code> to my <code>build.gradle</code> file and ran `"gradle build" to try and build the .java file. </p>
  
  <p>However, I am getting the error: <code>"Gradle is not recognised as an internal or external command"</code></p>
  
  <p>Do I need to install a <em>separate</em> version of Gradle, not bundled with AS to be able to build a <code>java</code> project? </p>
