title: Gradle compile dependency is not added to classpath
body: <p>I've added the reflections framework to my android project. However it wasn't added to the classpath. Android Studio suggests that I need to add it manually, however I cannot start my app since gradle cannot build it.</p>
  
  <p>Here is the build.gradle of my app module:</p>
  
  <pre><code>apply plugin: 'com.android.application'
  
  android {
      compileSdkVersion 22
      buildToolsVersion "21.1.2"
  
      defaultConfig {
          applicationId "my.package"
          minSdkVersion 21
          targetSdkVersion 22
          versionCode 1
          versionName "1.0"
      }
      buildTypes {
          release {
              minifyEnabled false
              proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
          }
      }
      lintOptions {
          abortOnError false
      }   
  }
  
  dependencies {
      compile fileTree(dir: 'libs', include: ['*.jar'])
      compile project(':offlinetasks')
      compile project(':tasks')
      compile project(':models')
      compile 'com.android.support:cardview-v7:21.0.3'
      compile 'com.android.support:recyclerview-v7:21.0.3'
  
      compile 'org.roboguice:roboguice:3.0.1'
      provided 'org.roboguice:roboblender:3.0.1'
  
      compile 'com.android.support:support-annotations:22.1.1'
      compile('org.reflections:reflections:0.9.10') {
          exclude module: 'xml-apis'
          exclude module: 'annotations'
      }
  
      testCompile 'junit:junit:4.12'
      testCompile('com.squareup.assertj:assertj-android:1.0.0') {
          exclude module: 'support-annotations'
      }
  }
  </code></pre>
  
  <p>When I build the app and try to use it I cannot import the Reflections class automatically. The only thing Android Studio suggests is to add the reflections framework manually.</p>

  <p>After I've added it to the classpath manually I can import the class. However when I'm trying to start it I get the following error:</p>
  
  <pre><code>tasks:compileReleaseJava
  /.../TaskFactory.java:8: error: package org.reflections does not exist
  import org.reflections.Reflections;
  </code></pre>
  
  <p>Does anyone know why this happens?</p>
  
  <p><strong>Edit:</strong>
  My project build.gradle looks like this:</p>
  
  <pre><code>// Top-level build file where you can add configuration options common to all sub-projects/modules.
  
  buildscript {
      repositories {
          jcenter()
          mavenCentral()
      }
      dependencies {
          classpath 'com.android.tools.build:gradle:1.2.3'
  
          // NOTE: Do not place your application dependencies here; they belong
          // in the individual module build.gradle files
      }
  }
  
  allprojects {
      repositories {
          jcenter()
          mavenCentral()
      }
  }
  </code></pre>
