Could not get unknown property 'processReleaseGoogleServices'

Question

I updated to use Android Studio 2.2 and Gradle 2.2.0. And now I have a problem building.

I followed this post https://medium.com/google-cloud/automatic-per-variant-google-services-json-configurations-with-gradle-d3d3e40abc0e#.g1p7c1tx2 to configure two "google-services.json" files to be used for dev vs prod builds and use the following method in my app/build.gradle file to toggle between the copying the two "google-services.json" files.

afterEvaluate {
    processDebugGoogleServices.dependsOn switchToDebug
    processReleaseGoogleServices.dependsOn switchToRelease
}

task switchToDebug(type: Copy) {
    description = 'Switches to DEBUG google-services.json'
    from "src/gcm-dev"
    include "google-services.json"
    into "."
}

task switchToRelease(type: Copy) {
    description = 'Switches to RELEASE google-services.json'
    from "src/gcm-prod"
    include "google-services.json"
    into "."
}

Gradle complies fine but when I click on the "Run app" (triangle "play" icon) or "Debug app" (triangle "play" icon with a bug behind) buttons in Android Studio, I get the following:

* What went wrong:
A problem occurred configuring project ':app'.
> Could not get unknown property 'processReleaseGoogleServices' for object of type com.android.build.gradle.AppExtension.

Please help, much appreciated.

You should update Google Play Services gradle plugin as well, follow the documentation to set it up: https://developers.google.com/android/guides/google-services-plugin

The great thing is that you no longer need to write gradle tasks which create appropriate google-services.json files in your root directory. Build type specific google-services.json are now supported by the plugin:

"As of version 2.2.0 the plugin supports build type and product flavor specific JSON files. All of the following directory structures are valid"

Answer 3

An alternative way to this is to refer to the task in the following way:

tasks.whenTaskAdded { task ->
    if (task.name == 'assembleDebug') {
        task.dependsOn 'switchToDebug'
    } else if (task.name == 'assembleRelease') {
        task.dependsOn 'switchToRelease'
    }
}

UPDATE

The problem you mentioned in comment is related to your google-services.json file. You need to place google-services.json into app/ dir. And for each build type there should be accordant director in app/src folder. If file already exists check if correct package name inside it

"client_info": {
"mobilesdk_app_id": "1:6596814400689:android:65d6f25f5006145",
"android_client_info": {
  "package_name": "com.my.app.package.name"
}

Answer 4

As described by @Singed, add a directory pr build type/flavor under src-directory and the corresponding google-services.jsonand Google Play gradle plugin will take care of the rest, e.g.:

src/
    debug/google-services.json
    release/google-services.json

During build the correct file will be processed, ending up in build/generated/res/google-services/debug|release/values/values.xml
