Working with the Gradle registry

ノート: サイト管理者はそれぞれのサポートされているパッケージの種類を有効化あるいは無効化できるので、このパッケージの種類はインスタンスで利用できないかもしれません。詳しい情� �については、「Enterprise 向けのパッケージサポートを設定する」を参照してく� さい。

Authenticating to GitHub Packages

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

You can use a personal access token (PAT) 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 PAT, 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 PAT to install packages associated with other private repositories (which GITHUB_TOKEN can't access).

GitHub Actionsワークフローで使われるGITHUB_TOKENに関する詳しい情� �については「ワークフローでの認証」を参照してく� さい。 For more information about using GITHUB_TOKEN with Gradle, see "Publishing Java packages with Gradle."

Authenticating with a personal access token

GitHub Packages内でパッケージを公開及びインストールするためには、適切なスコープで個人アクセストークンを使わなければなりません。詳しい情� �については「GitHub Packagesについて」を参照してく� さい。

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 user or organization account 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.

Note: GitHub PackagesはApache MavenのSNAPSHOTバージョンをサポートしています。 SNAPSHOT成果物をダウンロードするためにGitHub Packagesリポジトリを使うには、使用するプロジェクトのPOM中もしくは~/.m2/settings.xmlファイルでSNAPSHOTSを有効にしてく� さい。 For an example, see "Configuring Apache Maven for use with GitHub Packages."

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

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 the OWNER/test GitHub Packages repository.

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。詳しい情� �については「パッケージの表示」を参照してく� さい。

GitHub Packagesに認証を受けてく� さい。詳しい情� �については「GitHub Packagesへの認証を行う」を参照してく� さい。
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.

GitHub Packagesに認証を受けてく� さい。詳しい情� �については「GitHub Packagesへの認証を行う」を参照してく� さい。
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")
}
```

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")
        }
    }
}
