Proguard Printmapping not working in Android Studio 2.0.0 (and 2.1.0)

Using gradle wrapper 2.10, and Android Gradle build tools 2.0.0-beta7 2.1.0

From my build.gradle:

buildTypes {
        all{
            minifyEnabled  true
            proguardFiles = [getDefaultProguardFile("proguard-android.txt"), 'proguard-project.pro'];
        }
    }

This works. Things are obfuscated.

I have the following line in my proguard-project.pro as well:

-printmapping my-mapping.txt

Everything else in that file works fine, but the mapping keeps getting printed to the wrong place:

Printing mapping to [C:\path\to\my\project\build\outputs\mapping\debug\mapping.txt]

Has this syntax changed?

Note: I've tried supplying a direct path. I've tried supplying a name without a hyphen. Nothing changes.

For now I just made a gradle copy task for it.

Starting from Android Studio 3.5.3 and AGP 3.5.3 the -printmapping parameter is respected.

For example using:

-printmapping mapping.txt

It is copied from the default:

{projectRoot}\build\outputs\mapping\release\mapping.txt

to:

{projectRoot}\mapping.txt

Just try to start Android Studio as administrator.

-printmapping

may not write to system folder which cause this issue.

The mapping file at location build\outputs\mapping\debug\mapping.txt is the default one that gets generated even when you don't specify -printmapping my-mapping.txt inside proguard-project.pro. I see the name is always mapping.txt so -printmapping is being ignored with the new Android Studio version.

I remember it used to get generated at the same project root folder where proguard-project.pro is present but I confirm, it doesn't generate now with Android Studio 2.0 and is a bug that you can file at Android Issue Tracker.

Maybe you can change to follwoing

android {
    buildTypes {
        release {
            runProguard true
            proguardFiles getDefaultProguardFile('proguard-android.txt')，'some-other-rules.txt'
            //proguardFile 'some-other-rules.txt' 
        }
    }
}

Faced with same problem, but it seems that

{projectRoot}\build\outputs\mapping\debug\mapping.txt

is correct place for mapping files now
