new gradle `pluginManagement` do not find plugin `com.google.gms.google-services`

[danielesegato]

Following the new instructions to add google-services to my Android project I get this error:

org.gradle.internal.exceptions.LocationAwareException: Build file '.../app/build.gradle.kts' line: 1
Plugin [id: 'com.google.gms.google-services', version: '4.3.10'] was not found in any of the following sources:

- Gradle Core Plugins (plugin is not in 'org.gradle' namespace)
- Plugin Repositories (could not resolve plugin artifact 'com.google.gms.google-services:com.google.gms.google-services.gradle.plugin:4.3.10')
  Searched in the following repositories:
    Gradle Central Plugin Repository
    Google
    MavenRepo

As per instruction my settings.gradle.kts contains

pluginManagement {
  repositories {
    gradlePluginPortal()
    google()
    mavenCentral()
  }
  plugins {
    id("com.android.application") version "7.1.0-alpha13"
    id("com.android.library") version "7.1.0-alpha13"
    id("org.jetbrains.kotlin.android") version "1.5.21"
    id("com.google.gms.google-services") version "4.3.10" // <------
  }
}

while in my app/build.gradle.kts I've added:

plugins {
    id("com.android.application")
    kotlin("android")
    id("com.google.gms.google-services") // <-----
}

The instructions actually tells me to skip the declaration in the settings.gradle.kts and put the version directly in the app, I've tried that too, same result.

However, if I add in the root build.gradle.kts the legacy

buildscript {
  dependencies {
    classpath("com.google.gms:google-services:4.3.10")
  }
}

gradle can sync and it works as expected.

Isn't the new way supposed to replace the legacy one?

The issue is explained here https://github.com/square/wire/issues/1944

Apparently you forgot to publish the artifacts with the convention name and it isn't resolved.

the workaround is to add this inside the plugin management

pluginManagement {
    resolutionStrategy {
        eachPlugin {
            if (requested.id.id == "com.google.gms.google-services") {
                useModule("com.google.gms:google-services:4.3.10")
            }
        }
    }
}

Note that in the Wire issue they suggest to pass ${requested.version} in the useModule() but it gets resolved to null, failing, for me.

I had other plugins with the same issue so I used this syntax

    resolutionStrategy {
        eachPlugin {
            when (requested.id.id) {
                "com.google.gms.google-services" ->
                    useModule("com.google.gms:google-services:4.3.10")
                "com.google.firebase.crashlytics" ->
                    useModule("com.google.firebase:firebase-crashlytics-gradle:2.8.0")
                // etc.
            }
        }
    }

The wire issue doesn't fully spell it out I suppose, but for the resolution to work the plugin marker artifact should be published to maven.google.com.

~Usually the java-gradle-plugin sets this up, but that plugin isn't used in this project, but it can probably be added to the publish.gradle script.~

If you encounter other plugins not supporting this, ask them to publish the marker artifact too so no work arounds are needed.

The plugin descriptor is actually generated in the repo found in build/repo but it doesn't appear to be available on maven.google.com

Hello, this should be resolved now, as the extra artifact is now released to gmaven.
