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

According to this bug report, you can also use resolutionStrategy:

allprojects {
    repositories {
        mavenCentral()
        maven {
            url 'http://download.crashlytics.com/maven'
        }
    }
    configurations.all {
        resolutionStrategy.force 'com.android.support:support-annotations:22.2.0'
    }
}

This is the solution that worked for me and allowed me to use the most recent version of appcompat-v7 and appcompat-v4.
