                compile fileTree(dir:'libs',include: ['*.jar'])

                androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {

                excludegroup:'com.android.support',module:'support-annotations'

    })

                compile'com.android.support:appcompat-v7:27.+'

                compile'com.android.support.constraint:constraint-layout:1.0.2'

                testCompile'junit:junit:4.12'

}
