    // in the individual module build.gradle files
   }
}
allprojects {
     repositories {

Answer 1

Yes, with android gradle plugin 2.2.0 release, the android-apt plugin is no longer needed for annotation processing. The apt function was included in the latest android gradle plugin. It's called annotationProcessor now which was what you had in your build script. However, there were a few misconfigured stuff in the script.

First of all, the dagger compiler should not be added to classpath. So remove this line: classpath 'com.google.dagger:dagger-compiler:2.2'.

And you are using android gradle plugin version alpha3. Try to use the latest version, so change to classpath 'com.android.tools.build:gradle:2.2.2'.

The dependency declaration block looks legit. So try to make the above changes to see if it would work.
