How can I resolve the unsupported 'artifactregistry' protocol error in Gradle?

The error indicates that Gradle doesn’t recognize the protocol "artifactregistry" when resolving dependencies. Gradle expects repository URLs to use one of the supported protocols: file, http, https, gcs, s3, or sftp.

To resolve this issue you need to:

1. Change the Protocol
   Replace the "artifactregistry" protocol in your URL with "https". For example, if your artifact repository URL currently starts with
   artifactregistry://us-central1-maven.pkg.dev/your-project/your-repo
   change it to
   https://us-central1-maven.pkg.dev/your-project/your-repo

2. Update the Settings
   Adjust your Maven repository settings in settings.gradle so that the URL uses https. For instance, if you originally had:

   GROOVYCopied
   dependencyResolutionManagement {
       repositories {
           mavenCentral()
           gradlePluginPortal()
           maven {
               url "${artifactRepoBaseUrl}/mvn-snapshots"
           }
           mavenLocal()
       }
       versionCatalogs {
           create("libs") {
               from("com.xyz.build:build-logic:3.0.3-SNAPSHOT")
           }
       }
   }

   and artifactRepoBaseUrl is something like "artifactregistry://us-central1-maven.pkg.dev/your-project/your-repo", update it so the final URL will use https. You could modify it directly:

   GROOVYCopied
   dependencyResolutionManagement {
       repositories {
           mavenCentral()
           gradlePluginPortal()
           maven {
               // Replace "artifactregistry" with "https"
               url "https://us-central1-maven.pkg.dev/your-project/your-repo/mvn-snapshots"
           }
           mavenLocal()
       }
       versionCatalogs {
           create("libs") {
               from("com.xyz.build:build-logic:3.0.3-SNAPSHOT")
           }
       }
   }

3. Check Credentials and Access
   Ensure that you have the proper authentication (if required) configured for your Google Artifact Registry repository. This often means providing credentials via Gradle properties or environment variables.

By making sure that your repository URL uses the https protocol, Gradle will be able to resolve the dependencies and load the version catalog as expected.
