[Gradle][Proguard] Build fails giving confusing error about 11 duplicate class definitions

Mobile

-

How to reproduce:
1. Open the attached project
2. Set "Android" as the current target
3. Set "Gradle" as the build option
4. In player settings > publishing settings set existing keystore (you will find it in the project ../Keystore/TestKeyStore.jks , password is Unity77)
5. Build the project

Actual result: Build fails showing an error about 11 duplicate class definitions. Which is confusing.
Expected result: Error looks same as creating Development build - only real issue is explained that there are duplicate files during packaging of APK.

Reproducible: 2017.1.0p1, 2017.2.0b4, 2017.3.0a1
Proguard was introduced in 2017.1

By Design: The 11 duplicate class definitions error is expected. In the plugin page there's a section on how to set it up to work with proguard: https://support.vungle.com/hc/en-us/articles/204463100-Advanced-Settings-Vungle-Android-SDK-v-1-0-v-4-1

If you add that configuration to the user proguard file, the warning disappears and the build succeeds.

    I fixed after enable multiDexEnabled parameter on Assets/Plugins/Android/mainTemplate.gradle

    defaultConfig {
    minSdkVersion 15
    targetSdkVersion **TARGETSDKVERSION**
    multiDexEnabled true
    }
