I am trying to build an apk for the weather app and i am getting an error:

Error:Execution failed for task ':app:packageRelease'.

Unable to compute hash of /Volumes/SecondaryHD/HomeWork/AndroidProjects/Stormy/app/build/intermediates/classes-proguard/release/classes.jar

I even tried adding these lines to progurard-rules.pro but it didn't work either

-dontwarn java.nio.file.Files -dontwarn java.nio.file.Path -dontwarn java.nio.file.OpenOption -dontwarn org.codehaus.mojo.animal_sniffer.IgnoreJRERequirement -dontwarn android.net.http.AndroidHttpClient -dontwarn com.google.android.gms.**

Also based on your video i should have runProguard true line in my gradle file but i don't have it and adding it gives an error, i have minifyEnabled true instead

Please let me know how to fix this build error
