Android Gradle 3.0.0-alpha2 plugin, Cannot set the value of read-only property 'outputFile'

As Android plugin 3.0 migration guide suggests:

• Use all() instead of each()
• Use outputFileName instead of output.outputFile if you change only file name (that is your case)

Example from the guide:

// If you use each() to iterate through the variant objects,
// you need to start using all(). That's because each() iterates
// through only the objects that already exist during configuration time—
// but those object don't exist at configuration time with the new model.
// However, all() adapts to the new model by picking up object as they are
// added during execution.
android.applicationVariants.all { variant ->
    variant.outputs.all {
        outputFileName = "${variant.name}-${variant.versionName}.apk"
    }
}

See below:

applicationVariants.all { variant ->
    variant.outputs.all { output ->
        def newApkName = applicationId + "-" + variant.versionName + "(" + variant.versionCode + ")" + ".apk";
        outputFileName = new File("${project.projectDir}/../outputs/apks/" + variant.name, newApkName);
    }
}

Below code is working for me on android studio canary 3.0.0-alpha3

android.applicationVariants.all {
    variant.outputs.all {
        def newApkName
        newApkName = "APPLICATION_NAME-" + defaultConfig.versionName + "-" + defaultConfig.versionCode".apk"
        outputFileName = newApkName;
    }
}

This change the apk file name
