De模糊处理不适用于android studio 3.0

Question

I have my code obfuscated with proguard that runs when a release version is build and during the publish of the APK in the play console, I upload the mapping.txt file in "Vitals" section.

When an exception raises I can read clear code in stacktraces (in crashlytics and in Play console).

With previous version of Android studio (<= 2.3.3) all works regulary, now after the upgrade to Android studio 3.0 the same process will not de obfuscate stacktraces anymore.

I came across the migration of gradle plugin introducing the needed modifies

build.gradle (app):

    flavorDimensions "mode"
        productFlavors {
        full {
        dimension "mode"
        }
    }
    ...
    buildTypes {
    release {
        multiDexEnabled true
        minifyEnabled true
        proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        signingConfig signingConfigs.config
    }
    debug {
        ext.enableCrashlytics = false
        versionNameSuffix "-DEBUG"
        }
    }

What's wrong in the configuration? The mapping.txt file is correctly uploaded and accepted by Play Console. Any hint?

It's new in android, when you upload the mapping file, it Deobfuscate your code so you can understand the stack trace. This is the documentation link, it says:

If you use ProGuard to optimize and obfuscate your APK files, you can upload a ProGuard mapping file for each version of your app on the Play Console to deobfuscate your crash stack traces and help you better analyze your app's crashes.
