gar-credentials

This plugin replaces and simplifies the usage of Google authenticated artifact registries. This plugin exposes a extension method named garCliCredentials which replaces the method credentials {}when declaring a maven repository. Instead of the custom scheme used by the official plugin artifactregistry://, this plugin uses the classic https:// scheme.

This plugin was designed to be used with the centralized repository declaration syntax which uses the dependencyResolutionManagement{ } lambda in settings.gradle.kts files.

This plugin was tested on windows and linux/macos.

how-to

Apply the plugin into a settings.gradle.kts file like this:

// Put this code at the beginning of the settings.gradle.kts file
import com.decathlon.android.gradle.authenticatedgarcli.garCliCredentials

plugins {
    id("com.decathlon.gradle.authenticated-gar-cli")
}

Declare a maven repo like this

dependencyResolutionManagement {
    repositories {
        maven {
            setUrl("https://europe-west1-maven.pkg.dev/wonderful-repository")
            garCliCredentials(this)
        }
    }
}

Then, run a gradle sync. If the gcloud cli is not installed an exception will be fired. Once the cli is installed, the plugin will ask for the user to authenticate by running gcloud auth login. This will open the web browser automatically and will ask you to authenticate with your google account. When it's done, the gradle daemon will resume automatically the configuration phase and continue its execution.

Limitations

• C.I. are not supported yet, you have to run gcloud auth activate-service-account --key-file=/path/to/service-account.json before starting gradle or an other login method
• Only works with settings.gradle.kts files
• garCliCredentials method is a Kotlin extension to be used with gradle kts, groovy code was not tested

Help

Before submitting an issue, run your project with --info enabled like this ./gradlew --info and search for logs sent by the logger used in AuthenticatedGarCliPlugin.kt.

403 or 401 errors when downloading dependencies

This appends often when the active account in the gcloud CLI is not the right one. Run gcloud auth list into your IDE's terminal and check the account you're expecting to be used is correctly selected.

Python errors fired containing mach-o file, but is an incompatible architecture (have 'arm64', need 'x86_64')

We're not sure why this issue is fired but it appends sometimes, delete the folder ~/.config/gcloud/, uninstall Python3 and reinstall gcloud

TODO

• Releases: Add configuration to publish to the gradle plugin portal and setup to CI to publish automatically
• Service account support ? Useful when running this plugin on a C.I.
