Android Studio or Gradle does not compile dagger generated classes

I have one Android library that I created using the Dependency Injection Dagger ("br.com.estudio89: syncing: 1.0-SNAPSHOT"). The dependency manager that I used when building this library was Maven.

Now I am working on another project where I need to use this library, but this time I am using Gradle to manage dependencies.

What is happening now is that the classes generated by the dagger in my library are not compiling into my new application, causing a NoClassDefFoundError:

java.lang.NoClassDefFoundError: br.com.estudio89.syncing.injection.AppContextModule$$ModuleAdapter$ProvideAppContextProvidesAdapter

      

        
        
        
      

    

I also get the following errors:

05-03 01:26:48.147  30634-30634/br.com.estudio89.rhmais E/dalvikvm﹕ Could not find class 'dagger.internal.Binding', referenced from method dagger.internal.FailoverLoader.getAtInjectBinding

You can see the build.gradle file below:

buildscript {
    repositories {
        mavenCentral()
    }

    dependencies {
        classpath 'com.android.tools.build:gradle:1.2.2'
        classpath 'com.neenbedankt.gradle.plugins:android-apt:1.4'
    }
}

apply plugin: 'android'
apply plugin: 'com.neenbedankt.android-apt'

android {
    compileSdkVersion 21
    buildToolsVersion "21.0.0"

    defaultConfig {
        minSdkVersion 9
        targetSdkVersion 21
        multiDexEnabled = true
    }
    lintOptions {
        abortOnError false
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'),
                    'proguard-rules.pro'
        }
    }
}

repositories {
    mavenCentral()
    mavenLocal()
}

dependencies {

    apt 'com.squareup.dagger:dagger-compiler:1.2.2'
    compile 'com.squareup.dagger:dagger:1.2.2'
    apt 'br.com.estudio89:syncing:1.0-SNAPSHOT'

    compile (

    )
}

}

      

        
        
        
      

    

I don't know if this is a Gradle or Android Studio problem, but I tried everything I could and couldn't find a solution ... For the current project, I am not actually using the dagger, but I added it to the Gradle file in the hopes. that it will work ... Any help would be greatly appreciated!
