How to change the proguard mapping file name in gradle for Android project

Question

I have android project based on gradle and I want to change mapping.txt file name after it's generated for my build. How can it be done?

upd

How it can be done in build.gradle? Since I have access there to my flavors and other stiff, I would like to create mapping file name based on flavor/build variant version.

Simpler solution.

applicationVariants.all { variant ->         if (variant.getBuildType().isMinifyEnabled()) {             variant.assemble.doLast {                 copy {                     from variant.mappingFile                     into "${rootDir}/proguardTools"                     rename { String fileName ->                         "mapping-${variant.name}.txt"                     }                 }             }         }     }
