Configuring Apache Maven for use with GitHub Packages
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 is available with GitHub Free, GitHub Pro, GitHub Team, and GitHub Enterprise Cloud. For more information, see "GitHub's products."

Authenticating to GitHub Packages
You need an access token to publish, install, and delete packages in GitHub Packages. You can use a personal access token to authenticate with your username directly to GitHub Packages or the GitHub API. You can use a
GITHUB_TOKEN to authenticate using a GitHub Actions workflow.
Authenticating with a personal access token
You must use a personal access token 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. Create a new ~/.m2/settings.xml file if one doesn't exist.
servers tag, add a child
server tag with an
id, replacing USERNAME with your GitHub username, and TOKEN with your personal access token.
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 REPOSITORY with the name of the repository you'd like to publish a package to or install a package from, and OWNER with the name of the user or organization account that owns the repository. Because upper case 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

Note: GitHub Packages does not support SNAPSHOT versions of Apache Maven. Make sure you disable SNAPHOT in your ~/.m2/settings.xml file.

If you are using a GitHub Actions workflow, you can use a
GITHUB_TOKEN to publish and consume packages in GitHub Packages without needing to store and manage a personal access token. For more information, see "Authenticating with the
Publishing a package
By default, GitHub uses the package name to create a repository where the package will be published.
For example, GitHub will publish a package named
com.example.test in a repository called
If you would like to publish multiple packages to the same repository, you can include the URL of the repository in the
<scm> 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.
distributionManagementelement of the pom.xml file located in your package directory, replacing
OWNERwith the name of the user or organization account that owns the repository and
REPOSITORYwith the name of the repository containing your project.
<distributionManagement> <repository> <id>github</id> <name>GitHub OWNER Apache Maven Packages</name> <url>https://maven.pkg.github.com/OWNER/REPOSITORY</url> </repository> </distributionManagement>
Publish the package.
$ mvn deploy
After you publish a package, you can view the package on GitHub. For more information, see “Viewing a repository's packages.”
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.
Authenticate to GitHub Packages. For more information, see "Authenticating to GitHub Packages."
Add the package dependencies to the
dependencieselement of your project pom.xml file, replacing
com.example.testwith your package.
<dependencies> <dependency> <groupId>com.example</groupId> <artifactId>test</artifactId> <version>1.0.0</version> </dependency> </dependencies>
Install the package.
$ mvn install
