All these answers used copy to rename the file. I didn't want to move the file however, I just wanted to change it's name, keeping in mind the build type and flavor.

I based myself on the code from the other posters here and changed it up a bit. Since Minify can be false, while still using proguard, I just check if the file is present.

Following code accomplishes just that.

android {
    applicationVariants.all { variant ->
        variant.assemble.doLast {
            def mappingFolderUrl = "${project.buildDir.path}/outputs/mapping/"

            if (variant.buildType.name) {
                mappingFolderUrl += variant.buildType.name + "/"
            }

            if (variant.flavorName) {
                mappingFolderUrl += variant.flavorName + "/"
            }

            def mappingFileUrl = mappingFolderUrl + "mapping.txt"
            logger.lifecycle("mappingFile path: ${mappingFileUrl}")

            File mappingFile = file(mappingFileUrl)
            if (mappingFile.exists()) {
                def newFileName = mappingFolderUrl + "mapping-${variant.name}.txt"
                mappingFile.renameTo(newFileName)
            }
        }
    }
}

NOTE

You could probably use this code to move the file as well.

the .renameTo() method expects a full path, If you change the path, I would suppose you effectively move the File to another place.
