Working with the Apache Maven registry

You can configure Apache Maven to publish packages to GitHub Packages and to use packages stored on GitHub Packages as dependencies in a Java project.

GitHub Packages は、GitHub Free、GitHub Pro、Organization の GitHub Free、GitHub Team、GitHub Enterprise Cloud、GitHub Enterprise Server 3.0 以降、GitHub AE で利用できます。
GitHub Packagesは、レガシーのリポジトリごとのプランを使っているアカウントが所有しているプライベートリポジトリでは利用できません。 また、レガシーのリポジトリごとのプランを使っているアカウントは、リポジトリごとに課金される Container registry にはアクセスできません。 詳細については、「GitHub's products」を参照してください。

Authenticating to GitHub Packages

GitHub Packages では、personal access token (classic)を使用した認証のみがサポートされています。 詳しい情報については、「personal access tokenの作成」を参照してください。

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

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

To authenticate to a GitHub Packages registry within a GitHub Actions workflow, you can use:

  • GITHUB_TOKEN to publish packages associated with the workflow repository.
  • a personal access token (classic) with at least packages:read scope to install packages associated with other private repositories (which GITHUB_TOKEN can't access).

GitHub Actions ワークフローで使用される GITHUB_TOKEN の詳細については、「ワークフローで認証する」を参照してください。

Authenticating with a personal access token

You must use a personal access token (classic) with the appropriate scopes to publish and install packages in GitHub Packages. For more information, see "About GitHub Packages."

You can authenticate to GitHub Packages with Apache Maven by editing your ~/.m2/settings.xml file to include your personal access token (classic). 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 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.

GitHub Packages では Apache Maven の SNAPSHOT バージョンがサポートされています。 SNAPSHOT 成果物のダウンロードに GitHub Packages リポジトリを使用するには、それを使用するプロジェクトまたは ~/.m2/settings.xml ファイルの POM で SNAPSHOTS を有効にします。

Publishing a package

デフォルトでは、GitHubはパッケージはそのままの名前で既存のリポジトリに公開されます。 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 documentation.

  1. Edit the distributionManagement element of the pom.xml file located in your package directory, replacing 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.

         <name>GitHub OWNER Apache Maven Packages</name>
  2. Publish the package.

    $ mvn deploy

パッケージを公開した後は、GitHub上でそのパッケージを見ることができます。 詳しくは、「パッケージの表示」をご覧ください。

Installing a package

To install an Apache Maven package from GitHub Packages, 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. GitHub Packagesに認証を受けてください。 詳細については、「GitHub Packages への認証」を参照してください。

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

  3. Install the package.

    $ mvn install
