Authenticating to GitHub Packages

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

You can use a personal access token to authenticate to GitHub Packages 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 personal access token, 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 with at least read:packages scope to install packages associated with other private repositories (which GITHUB_TOKEN can't access).

For more information about GITHUB_TOKEN used in GitHub Actions workflows, see "Automatic token authentication." For more information about using GITHUB_TOKEN with Gradle, see "Publishing Java packages with Gradle."

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 "Introduction to GitHub Packages."

You can authenticate to GitHub Packages with Gradle using either Gradle Groovy or Kotlin DSL by editing your build.gradle file (Gradle Groovy) or build.gradle.kts file (Kotlin DSL) file to include your personal access token. You can also configure Gradle Groovy and Kotlin DSL to recognize a single package or multiple packages in a repository.

Replace REGISTRY_URL with the URL for your instance's Maven registry. If your instance has subdomain isolation enabled, use maven.HOSTNAME. If your instance has subdomain isolation disabled, use HOSTNAME/_registry/maven. In either case, replace HOSTNAME with the host name of your GitHub Enterprise Server instance.

Replace USERNAME with your GitHub username, TOKEN with your personal access token, REPOSITORY with the name of the repository containing the package you want to publish, and OWNER with the name of the personal account or organization on GitHub 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.

Example using Gradle Groovy for a single package in a repository

plugins {
    id("maven-publish")
}
publishing {
    repositories {
        maven {
            name = "GitHubPackages"
            url = uri("https://REGISTRY_URL/OWNER/REPOSITORY")
            credentials {
                username = project.findProperty("gpr.user") ?: System.getenv("USERNAME")
                password = project.findProperty("gpr.key") ?: System.getenv("TOKEN")
            }
        }
    }
    publications {
        gpr(MavenPublication) {
            from(components.java)
        }
    }
}

Example using Gradle Groovy for multiple packages in the same repository

plugins {
    id("maven-publish") apply false
}
subprojects {
    apply plugin: "maven-publish"
    publishing {
        repositories {
            maven {
                name = "GitHubPackages"
                url = uri("https://REGISTRY_URL/OWNER/REPOSITORY")
                credentials {
                    username = project.findProperty("gpr.user") ?: System.getenv("USERNAME")
                    password = project.findProperty("gpr.key") ?: System.getenv("TOKEN")
                }
            }
        }
        publications {
            gpr(MavenPublication) {
                from(components.java)
            }
        }
    }
}

Example using Kotlin DSL for a single package in the same repository

plugins {
    `maven-publish`
}
publishing {
    repositories {
        maven {
            name = "GitHubPackages"
            url = uri("https://REGISTRY_URL/OWNER/REPOSITORY")
            credentials {
                username = project.findProperty("gpr.user") as String? ?: System.getenv("USERNAME")
                password = project.findProperty("gpr.key") as String? ?: System.getenv("TOKEN")
            }
        }
    }
    publications {
        register<MavenPublication>("gpr") {
            from(components["java"])
        }
    }
}

Example using Kotlin DSL for multiple packages in the same repository

plugins {
    `maven-publish` apply false
}
subprojects {
    apply(plugin = "maven-publish")
    configure<PublishingExtension> {
        repositories {
            maven {
                name = "GitHubPackages"
                url = uri("https://REGISTRY_URL/OWNER/REPOSITORY")
                credentials {
                    username = project.findProperty("gpr.user") as String? ?: System.getenv("USERNAME")
                    password = project.findProperty("gpr.key") as String? ?: System.getenv("TOKEN")
                }
            }
        }
        publications {
            register<MavenPublication>("gpr") {
                from(components["java"])
            }
        }
    }
}

Publishing a package

By default, GitHub publishes the package to an existing repository with the same name as the package. For example, GitHub will publish a package named com.example.test in the OWNER/test GitHub Packages repository.

After you publish a package, you can view the package on GitHub. For more information, see "Viewing packages."

1. Authenticate to GitHub Packages. For more information, see "Authenticating to GitHub Packages."

2. After creating your package, you can publish the package.

    gradle publish
   

Using a published package

To use a published package from GitHub Packages, add the package as a dependency and add the repository to your project. For more information, see "Declaring dependencies" in the Gradle documentation.

1. Authenticate to GitHub Packages. For more information, see "Authenticating to GitHub Packages."

2. Add the package dependencies to your build.gradle file (Gradle Groovy) or build.gradle.kts file (Kotlin DSL) file.

   Example using Gradle Groovy:

   dependencies {
       implementation 'com.example:package'
   }
   

   Example using Kotlin DSL:

   dependencies {
       implementation("com.example:package")
   }
   

3. Add the repository to your build.gradle file (Gradle Groovy) or build.gradle.kts file (Kotlin DSL) file.

   Example using Gradle Groovy:

   repositories {
       maven {
           url = uri("https://REGISTRY_URL/OWNER/REPOSITORY")
           credentials {
               username = project.findProperty("gpr.user") ?: System.getenv("USERNAME")
               password = project.findProperty("gpr.key") ?: System.getenv("TOKEN")
           }
      }
   }
   

   Example using Kotlin DSL:

   repositories {
       maven {
           url = uri("https://REGISTRY_URL/OWNER/REPOSITORY")
           credentials {
               username = project.findProperty("gpr.user") as String? ?: System.getenv("USERNAME")
               password = project.findProperty("gpr.key") as String? ?: System.getenv("TOKEN")
           }
       }
   }
