variant.assemble is now deprecated, suggested solution incorporating previous modifications:

archivesBaseName = "MyCompany-MyAppName-$versionName"
...
applicationVariants.all { variant ->
    variant.assembleProvider.get().doLast {
        if (variant.mappingFile != null && variant.mappingFile.exists()) {
            def mappingFilename = "$archivesBaseName-$variant.baseName-mapping.txt"
        (new File(variant.mappingFile.parent, mappingFilename)).delete()
        variant.mappingFile.renameTo(variant.mappingFile.parent +
                "/" + mappingFilename)
        }
    }
}

If using app bundle (aab) instead of apk, add this to after the android section:

afterEvaluate {
    bundleRelease.doLast {
        android.applicationVariants.all { variant ->
            if (variant.buildType.name == 'release') {
                tasks.create(name: "renameMappingFile") {
                    if (variant.mappingFile != null && variant.mappingFile.exists()) {
                        variant.mappingFile.renameTo(variant.mappingFile.parent + "/$variant.baseName-$versionName-${new Date().format('yyyy-MM-dd_HHmm')}-mapping.txt")
                    }
                }
            }
        }
    }
}

Swap bundleRelease for assembleRelease for apks in the last example too.

Update: However that last doesn't work if you try and build a normal debug directly to your phone then. Error:

Could not get unknown property 'bundleRelease' for project ':app' of type org.gradle.api.Project.
