Gradle Android Test fails runtime

I am beginner in Gradle Android Tests and I've found some problems when I try launch my test.

This is my build.gradle:

// Top-level build file where you can add configuration options common to all sub-projects/ modules.
buildscript {
    repositories {
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:1.0.0'
    }
}

allprojects {
    repositories {
        jcenter()
    }
}

apply plugin: 'com.android.library'


android {
    compileSdkVersion 23
    buildToolsVersion "23.0.3"

    defaultConfig {
        minSdkVersion 18
        targetSdkVersion 23
        versionCode 1
        versionName "1.0"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }

    def codeGradiantLicenseControlJavaCommon = '../../code/common'

    sourceSets {
        main {
            java.srcDir codeGradiantLicenseControlJavaCommon
        }
    }

    defaultConfig {
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    }

    lintOptions {
        abortOnError false
    }
}


sourceSets {
    androidTest {
        java.srcDir file('src/androidTest/java')
    }
}

configurations {
    androidtTestCompile.extendsFrom runtime
    androidtTestRuntime.extendsFrom androidtTestCompile
}

dependencies {
    androidtTestCompile files("$project.buildDir/classes/release")
}

dependencies {
    compile 'com.android.support:appcompat-v7:23.+'
    compile fileTree(dir: 'libs', include: ['*.jar'])

    androidTestCompile 'junit:junit:4.12'

    androidTestCompile 'com.android.support:support-annotations:23.0.0'
    androidTestCompile 'com.android.support.test:runner:0.5'
    androidTestCompile 'com.android.support.test:rules:0.5'
    // Optional -- Hamcrest library
    androidTestCompile 'org.hamcrest:hamcrest-library:1.3'
    // Optional -- UI testing with Espresso
    androidTestCompile 'com.android.support.test.espresso:espresso-core:2.2.2'
    // Optional -- UI testing with UI Automator
    androidTestCompile 'com.android.support.test.uiautomator:uiautomator-v18:2.1.2'
    //Mockito
    androidTestCompile "org.mockito:mockito-core:1.+"
}





task createJar(type: Copy) {
    from('build/intermediates/bundles/release/')
    into('build/libs/')
    include('classes.jar')
    rename ('classes.jar', 'GradiantLicenseControl.jar')
}

task androidTest(group: "verification", type: Test) {
    systemProperty "java.library.path", "src/androidTest/jniLibs"
    testClassesDir = sourceSets.androidTest.output.classesDir
    classpath = sourceSets.androidTest.runtimeClasspath
    androidTest.reports.html.destination = file("$buildDir/reports/androidTest")
}

And in Editor everything looks good, but when I execute gradle adroiTest not recognizes classes I'd imported:

Incremental java compilation is an incubating feature.
:library:compileAndroidTestJava
/Users/eutelobarreiro/Software/license-manager/projects/java/GradiantLicenseControlAndroid/library/src/androidTest/java/org/gradiant/license/control/GradiantLicenseControlNoLicenseTest.java:3: error: package android.content does not exist
import android.content.Context;

What is wrong in my build.gradle?

Thanks
