Android tests build error: Multiple dex files define Landroid/support/test/BuildConfig

Question

I\'m trying to add Espresso 2 to my project (which also has lots of other dependencies), but I\'m hitting this error when trying to run tests:

UNEXPECTED TOP         


        

Answer 1

My solution:

compile 'com.android.support:appcompat-v7:22.1.0'
androidTestCompile 'com.android.support.test.espresso:espresso-core:2.1'
androidTestCompile 'com.android.support:support-annotations:22.1.0'
androidTestCompile 'com.android.support.test:runner:0.2'

+

android {
    packagingOptions {
        exclude 'LICENSE.txt'
   }
}
