title: No build.gradle is created when importing an existing Java project with Gradle in Eclipse
body: <p>I have Java projects in Eclipse Mars. I have Buildship 1.0.21 and Gradle 3.1. In Eclipse I right click a project and press <code>Import &gt; Gradle Project</code> and go through the wizard. When I'm done my project has its Gradle nature <code>G</code> symbol but no <code>build.gradle</code>, gradle wrapper folder or anything else gradle related (my other "real" projects have <code>gradlew</code> and <code>gradle.bat</code> files too).</p>
  
  <p>Why does this happen and how to I fix this?</p>
