Where is the proguard mapping file in Android studio [duplicate]

In android studio(2.2.2) where are the proguard mapping files generated after generating a signed APK?

I have Generated Signed Apk file and follow below two paths but in my root folder i did not get any "mapping.txt" file

For debug: \app\build\outputs\mapping\debug\mapping.txt

For release: \app\build\outputs\mapping\release\mapping.txt

please suggest me how can i get this "mapping.txt" file?

Do you has been generate proguard mapping ?

in proguard-rules.pro type it -printmapping {location}/filename.txt .

example :

For debug

-printmapping build/outputs/mapping/debug/mapping.txt

For release

-printmapping build/outputs/mapping/release/mapping.txt
