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

Try excluding the following from espresso (one at a time):

androidTestCompile('com.android.support.test.espresso:espresso-core:2.1') {
  exclude group: 'javax.inject'
  exclude group: 'com.google.code.findbugs'
  exclude group: 'com.android.support', module: 'support-annotations'
}

Probably need to do the same with runner
