Where are the output files of Android Wear Proguard

Question

I have Proguard enabled for both a wearable app and a mobile app using gradle in Android Studio (0.8.2). I know that proguard is enabled since I placed Thread.dumpStack () in both applications and the hidden code exits. I found the output files of mobile proguard, including mappings.txt, and checked there my classes of mobile methods, etc. Everything is still beautiful. But then

Where are proguard output files for clothes stored? I checked the mappings.txt file for any wear related methods, but did not find them. Also check all other folders of my project.

I use the wearApp gradle rule to build.

Gradle wear includes:

productFlavors {
    freeapp {
        applicationId "com.barkside.app"
    }
}
buildTypes {
    release {
        runProguard true
        proguardFiles getDefaultProguardFile('proguard-android.txt'), 
             'proguard-project.txt'
    }
}

Mobile gradle includes:

dependencies {
    wearApp project(path: ':wear', configuration: 'freeappRelease')
