Google Artifact Registry SBT plugin

An SBT dependency resolver and publisher for Google Artifact Registry Maven repositories.

It is implemented as a wrapper around Artifact Registry Maven Tools.

Usage

Add the following to plugins.sbt in your project:

addSbtPlugin("ch.firsts" % "sbt-google-artifact-registry" % "1.0.0")

To use this plugin as a resolver, add the following to build.sbt:

resolvers += ArtifactRegistryResolver.forRepository("https://<REGION>-maven.pkg.dev/<PROJECT>/<REPOSITORY>")

To use the plugin to publish artifacts:

publishTo := Some(ArtifactRegistryResolver.forRepository("https://<REGION>-maven.pkg.dev/<PROJECT>/<REPOSITORY>"))

The specified Maven repository should already exist in the Google Artifact Registry.
For development on local computer the user has to be logged-in into the gcloud command line tool with credentials which have IAM permissions to read or write the Maven repository.

Coursier is not supported. When using recent SBT versions where Coursier artifact resolution is enabled by default, it has to be disabled by adding useCoursier := false to build.sbt, since Coursier partially uses it's own code to resolve artifacts, which does not fully depend on the resolvers to download the artifacts.
Publishing multiple SNAPSHOTS of the same version is not supported. The plugin uses Ivy IBiblioResolver as the base implementation, which hardcodes maven metadata locations in a way that is not compatible with the SBT.
