title: Configuration with name 'default' not found. Android Studio
body: <p>I have an Android Studio app. It has a library dependency (Android-Bootstrap), when I try to sync gradle, it gives me an error:</p>
  
  <blockquote>
    <p>Configuration with name 'default' not found.</p>
  </blockquote>
  
  <p>My structure is:</p>
  
  <pre><code>-FTPBackup
     -fotobackup
       -build.gradle
     -Libraries
       -Android-Bootstrap
         -Settings.gradle
         -build.gradle
  -Settings.gradle
  -Build.gradle
  </code></pre>
  
  <p>The FTPBackup settings.gradle and build.gradle:</p>
  
  <pre><code>include ':fotobackup'
  include ':libraries:Android-Bootstrap',':Android-Bootstrap'
  </code></pre>
  
  <hr>
  
  <pre><code>// Top-level build file where you can add configuration options common to all sub-projects/modules.
  
  buildscript {
      repositories {
          mavenCentral()
      }
      dependencies {
          classpath 'com.android.tools.build:gradle:0.9.+'
      }
  }
  
  allprojects {
      repositories {
          mavenCentral()
      }
  }
  </code></pre>
  
  <p>And the build.gradle inside fotobackup is:</p>
  
  <pre><code>apply plugin: 'android'
  
  android {
      compileSdkVersion 19
      buildToolsVersion '19.0.3'
  
      defaultConfig {
          minSdkVersion 14
          targetSdkVersion 19
          versionCode 1
          versionName "1.0"
      }
      buildTypes {
          release {
              runProguard false
              proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.txt'
          }
      }
  }
  
  apply plugin: 'android'
  
  dependencies {
      compile fileTree(dir: 'libs', include: ['*.jar'])
      compile 'com.android.support:support-v4:+'
      compile project (':libraries:Android-Bootstrap')
  }
  </code></pre>
  
  <p>The library is downloaded from <a href="https://github.com/Bearded-Hen/Android-Bootstrap" rel="nofollow noreferrer">https://github.com/Bearded-Hen/Android-Bootstrap</a> and it has build.gradle, settings etc.</p>
  
  <p>whats wrong?</p>
