title: Failed to resolve com.melnykov:floatingactionbutton:1.3.0 in gradle
body: <p>I apologize if I am missing something obvious, but I recently converted my project from Eclipse to Android Studio (and Gradle) and am trying to add support for Floating Action Buttons using <a href="https://github.com/makovkastar/FloatingActionButton" rel="nofollow">Melnykov's library</a>, but Gradle cannot resolve it. I thought it was a simple matter of adding <code>compile 'com.melnykov:floatingactionbutton:1.3.0'</code> to my app's <code>build.gradle</code> file. Am I missing something or is the source not available to download or what? Thanks ahead of time. </p>
  
  <p>My app's <code>build.gradle</code> file:</p>
  
  <pre><code>apply plugin: 'android'
  
  dependencies {
      compile 'com.android.support:support-v4:22.1.0'
      compile files('libs/opencsv-3.1.jar')
      compile 'com.android.support:appcompat-v7:22.1.0'
      compile 'com.melnykov:floatingactionbutton:1.3.0'
  }
  
  android {
      compileSdkVersion 22
      buildToolsVersion "22"
  
      sourceSets {
          main {
              manifest.srcFile 'AndroidManifest.xml'
              java.srcDirs = ['src']
              resources.srcDirs = ['src']
              aidl.srcDirs = ['src']
              renderscript.srcDirs = ['src']
              res.srcDirs = ['res']
              assets.srcDirs = ['assets']
          }
  
          // Move the tests to tests/java, tests/res, etc...
          instrumentTest.setRoot('tests')
  
          // Move the build types to build-types/&lt;type&gt;
          // For instance, build-types/debug/java, build-types/debug/AndroidManifest.xml, ...
          // This moves them out of them default location under src/&lt;type&gt;/... which would
          // conflict with src/ being used by the main source set.
          // Adding new build types or product flavors should be accompanied
          // by a similar customization.
          debug.setRoot('build-types/debug')
          release.setRoot('build-types/release')
      }
  }
