Working with the Apache Maven registry

Authenticating to Registro del paquete de GitHub

You need an access token to publish, install, and delete packages.

You can use a personal access token (PAT) to authenticate to Registro del paquete de GitHub or the GitHub Enterprise Server API. When you create a personal access token, you can assign the token different scopes depending on your needs. For more information about packages-related scopes for a PAT, see "About permissions for GitHub Packages."

To authenticate to a Registro del paquete de GitHub registry within a GitHub Actions workflow, you can use:

• GITHUB_TOKEN to publish packages associated with the workflow repository.
• a PAT to install packages associated with other private repositories (which GITHUB_TOKEN can't access).

Para obtener más información sobre el GITHUB_TOKEN que se utiliza en los flujos de trabajo de GitHub Actions, consulta la sección "Autenticarse en un flujo de trabajo".

Authenticating with a personal access token

Debes utilizar un token de acceso personal con los alcances adecuados para publicar e instalar paquetes en Registro del paquete de GitHub. Para obtener más información, consulta "Acerca de Registro del paquete de GitHub".

You can authenticate to Registro del paquete de GitHub with Apache Maven by editing your ~/.m2/settings.xml file to include your personal access token. Create a new ~/.m2/settings.xml file if one doesn't exist.

In the servers tag, add a child server tag with an id, replacing USERNAME with your GitHub username, and TOKEN with your personal access token.

In the repositories tag, configure a repository by mapping the id of the repository to the id you added in the server tag containing your credentials. Replace HOSTNAME with the host name of tu instancia de GitHub Enterprise Server, and OWNER with the name of the user or organization account that owns the repository. Because uppercase letters aren't supported, you must use lowercase letters for the repository owner even if the GitHub user or organization name contains uppercase letters.

If you want to interact with multiple repositories, you can add each repository to separate repository children in the repositories tag, mapping the id of each to the credentials in the servers tag.

Registro del paquete de GitHub es compatible con versiones SNAPSHOT de Apache Maven. Para utilizar el repositorio del Registro del paquete de GitHub para descargar artefactos de SNAPSHOT, habilita las SNAPSHOTS en el POM del proyecto consumidor en tu archivo ~/.m2/settings.xml.

Publishing a package

Predeterminadamente, GitHub publica el paquete en un repositorio existente con el mismo nombre que éste. For example, GitHub will publish a package named com.example:test in a repository called OWNER/test.

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. GitHub 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.

1. Edit the distributionManagement element of the pom.xml file located in your package directory, replacing HOSTNAME with the host name of tu instancia de GitHub Enterprise Server, OWNER with the name of the user or organization account that owns the repository and REPOSITORY with the name of the repository containing your project.

   If your instance has subdomain isolation enabled:

   <distributionManagement>
      <repository>
        <id>github</id>
        <name>GitHub OWNER Apache Maven Packages</name>
        <url>https://maven.HOSTNAME/OWNER/REPOSITORY</url>
      </repository>
   </distributionManagement>
   

   If your instance has subdomain isolation disabled:

   <distributionManagement>
      <repository>
        <id>github</id>
        <name>GitHub OWNER Apache Maven Packages</name>
        <url>https://HOSTNAME/_registry/maven/OWNER/REPOSITORY</url>
      </repository>
   </distributionManagement>
   

2. Publish the package.

   $ mvn deploy

Después de que publiques un paquete, puedes verlo en GitHub. Para obtener más información, consulta "Visualizar paquetes".

Installing a package

To install an Apache Maven package from Registro del paquete de GitHub, edit the pom.xml file to include the package as a dependency. If you want to install packages from more than one repository, add a repository tag for each. For more information on using a pom.xml file in your project, see "Introduction to the POM" in the Apache Maven documentation.

1. Autentícate en Registro del paquete de GitHub. Para obtener más información, consulta "Autenticar a Registro del paquete de GitHub."

2. Add the package dependencies to the dependencies element of your project pom.xml file, replacing com.example:test with your package.

   <dependencies>
     <dependency>
       <groupId>com.example</groupId>
       <artifactId>test</artifactId>
       <version>1.0.0-SNAPSHOT</version>
     </dependency>
   </dependencies>
   

3. Install the package.

   $ mvn install
