Google Cloud Artifact Registry for Gradle plugins

Question

I have successfully published to Artifact Registry, and I can use artifacts from there in "normal" use: dependencies { implementation("mygroup:myartifact:myversion") }.

My issue is plugins. I have created a plugin. I can successfully publish it to Artifact Registry and also to Maven local. I can use it from Maven local, but I can't get my build script to take it from Artifact Registry.

buildscript {
    repositories {
        maven(url = uri("artifactregistry://us-west1-maven.pkg.dev/glitchy-maven/repo"))
    }
}

plugins {
    id("com.google.cloud.artifactregistry.gradle-plugin") version "2.1.1"
    id("com.glitchybyte.gradle.plugin.buildinfo") version "1.0.0"
    `java-library`
}

And I get:

* What went wrong:
Plugin [id: 'com.glitchybyte.gradle.plugin.buildinfo', version: '1.0.0'] 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.glitchybyte.gradle.plugin.buildinfo:com.glitchybyte.gradle.plugin.buildinfo.gradle.plugin:1.0.0')
  Searched in the following repositories:
    Gradle Central Plugin Repository

So, it's not looking into Artifact Registry for plugins. I know I'm missing something, but I don't know what.

...Update...

I removed buildscript from build.gradle.kts, and instead I added this to settings.gradle.kts:

pluginManagement {
    plugins {
        id("com.google.cloud.artifactregistry.gradle-plugin") version "2.1.1"
    }
    repositories {
        maven(url = uri("artifactregistry://us-west1-maven.pkg.dev/glitchy-maven/repo"))
    }

And I get:

* What went wrong:
Error resolving plugin [id: 'com.glitchybyte.gradle.plugin.buildinfo', version: '1.0.0']
> Could not resolve all dependencies for configuration 'detachedConfiguration1'.
   > Not a supported repository protocol 'artifactregistry': valid protocols are [http, https, file, gcs, s3, sftp]

Answer 1

For whoever ends up here like me looking for a solution. I found mine here.

Add the following to your settings.gradle(.kts)

buildscript {
    repositories {
        gradlePluginPortal()
    }
    dependencies {
        classpath("gradle.plugin.com.google.cloud.artifactregistry:artifactregistry-gradle-plugin:latest.release")
    }
}
apply(plugin = "com.google.cloud.artifactregistry.gradle-plugin")

My full settings gradle file:

pluginManagement{
    repositories{
        gradlePluginPortal()
        mavenLocal()
        maven {
            url = uri("artifactregistry://us-west1-maven.pkg.dev/some-artifact-storage/my-release")
        }
    }
}
buildscript {
    repositories {
        gradlePluginPortal()
    }
    dependencies {
        classpath("gradle.plugin.com.google.cloud.artifactregistry:artifactregistry-gradle-plugin:latest.release")
    }
}

apply(plugin = "com.google.cloud.artifactregistry.gradle-plugin")

rootProject.name = "some-application"

Hello Sorry for the late answer. I think you are missing this part of the configuration to be added to your settings.gradle.kts

buildscript {
    repositories {
        maven {
            url = uri("https://plugins.gradle.org/m2/")          }
    }
    dependencies {
        classpath("gradle.plugin.com.google.cloud.artifactregistry:artifactregistry-gradle-plugin:2.2.0")
    }
}
apply(plugin =  "com.google.cloud.artifactregistry.gradle-plugin")
