title: How to create Gradle build for existing IDEA project?
body: <p>I have a Groovy project in Intellij IDEA 13.1.5 that I want to build with Gradle. So I have installed Gradle itself and enabled the Gradle plugin in IDEA.</p>
  
  <p>But how can I now build the project (or better: start to write the Gradle build file) from within IDEA? I have created a <code>build.gradle</code> file in the project's module, which is recognized by IDEA correctly as Gradle file, according to the icon next to the file name.</p>
  
  <p>Beside that I don't know how to continue from there. IDEA documentation says I should open the Gradle Tools window, but I can find it in View --> Tool Windows.</p>
  
  <p>Any ideas?</p>
