 The `groupId` and `artifactId` fields in the _pom.xml_ file create a unique identifier for your package that registries use to link your package to a registry. For more information see [Guide to uploading artifacts to the Central Repository](https://maven.apache.org/repository/guide-central-repository-upload.html) in the Apache Maven documentation.

 The _pom.xml_ file also contains configuration for the distribution management repositories that Maven will deploy packages to. Each repository must have a name and a deployment URL. Authentication for these repositories can be configured in the _.m2/settings.xml_ file in the home directory of the user running Maven.
 
 You can use the `setup-java` action to configure the deployment repository as well as authentication for that repository. For more information, see [`setup-java`](https://github.com/actions/setup-java).

 If you would like to publish multiple packages to the same repository, you can include the URL of the repository in the `<distributionManagement>` element of the _pom.xml_ file. {% data variables.product.prodname_dotcom %} will match the repository based on that field. Since the repository name is also part of the `distributionManagement` element, there are no additional steps to publish multiple packages to the same repository.
 
 For more information on creating a package, see the [maven.apache.org documentation](https://maven.apache.org/guides/getting-started/maven-in-five-minutes.html).

For more information, see [Naming convention of Maven coordinates](https://maven.apache.org/guides/mini/guide-naming-conventions.html) in the maven.apache.org documentation. If you use upercase letters in the artifact name, you'll get a _422 Unprocessable Entity_ response.
