How to apply the com.android.application plugin using the new plugins DSL?

I have a project configured through the triple of:

  • Declare repository in top-level build.gradle:

    buildscript { repositories { google() }}
allprojects { repositories { google() }}

  • Declare classpath dependency, so plugin artifact gets downloaded from the appropriate repository, in top-level build.gradle

    buildscript { dependencies { classpath 'com.android.tools.build:gradle:3.1.3' }}

  • Then, in the app build.gradle file, apply the plugin:

    apply plugin: 'com.android.application'

I want to migrate this to use the new plugins DSL as enabled by the PluginsDependenciesSpec.

I then:

  • Declared the repository in settings.gradle:

    pluginManagement { repositories { google() }}

  • Declared the plugin dependency in the app build.gradle:

    plugins { id "com.android.application" version "3.1.3" }

But this fails to resolve:

FAILURE: Build failed with an exception.

  • Where: Build file '…/build.gradle' line: 2

  • What went wrong: Plugin [id: 'com.android.application', version: '3.1.3'] 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.android.library:com.android.library.gradle.plugin:3.1.3')

Searched in the following repositories:

What am I missing to get Gradle to connect the dots here, so that it can connect the plugin.id to the appropriate JAR fetched from the appropriate repository?

Within the pluginManagement you can use resolutionStrategy and force usage of specific artifact from the google() repository.

pluginManagement {
    repositories {
        google()
    }

    resolutionStrategy {
        eachPlugin {
            if (requested.id.id in ['com.android.application', 'com.android.library']) {
                useModule("com.android.tools.build:gradle:${getProperty('version.plugin.android')}")
            }
        }
    }
}

Then you can apply android plugins with using new plugins DSL:

plugins {
    id 'com.android.application'
}

or

plugins {
    id 'com.android.library'
}

Here is the documentation.
