title: Unable to see dependency tree with gradlew OR gradle
body: <p>I'm running the latest release of gradle (1.12). In the project's root directory, I run the following command, which as described in <a href="https://stackoverflow.com/a/21100040/588758">this answer</a> by @CommonsWare should give the dependency tree:</p>
  
  <p>When I run it, this happens:</p>
  
  <p><strong>$ gradle -q dependencies</strong></p>
  
  <pre><code>------------------------------------------------------------
  Root project
  ------------------------------------------------------------
  
  No configurations
  </code></pre>
  
  <p>The project in question is an Android gradle project created from scratch using the new project wizard built in with Android Studio. My top-level build.gradle file looks like this:</p>
  
  <pre><code>buildscript {
      repositories {
          mavenCentral()
      }
      dependencies {
          classpath 'com.android.tools.build:gradle:0.10.+'
      }
  }
  
  allprojects {
      repositories {
          maven { url "http://dl.bintray.com/populov/maven" }
          mavenCentral()
      }
  }
  
  subprojects {
      repositories {
          flatDir {
              dirs "$rootDir/libs"
          }
      }
  }
  </code></pre>
  
  <p>And my settings.gradle file looks like this:</p>
  
  <pre><code>include ':app', ':facebook', 'pullToRefresh'
  </code></pre>
  
  <p>From what I understand this is a very basic gradle configuration. Does anyone have an idea why the dependency tree function is returning nothing? Let me know if I need to provide more information.</p>
