Working with the Gradle registry

注意：这种包类型可能不适用于� 的实例，� 为站点管理员可以启用或禁用每种支持的包类型。有关详细信息，请参阅“为企业配置包支持”。

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 packages:read scope to install packages associated with other private repositories (which GITHUB_TOKEN can't access).

有关 GitHub Actions 工作流中使用的 GITHUB_TOKEN 的详细信息，请参阅“工作流中的身份验证”。 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 "About 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 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 支持 Apache Maven 的 SNAPSHOT 版本。要使用 GitHub Packages 存储库下载 SNAPSHOT 工件，请在所用项目的 POM 或 ~/.m2/settings.xml 文件中启用 SNAPSHOTS。 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

默认情况下，GitHub 将包发布到名称与包相同的现有仓库中。 For example, GitHub will publish a package named com.example.test in the OWNER/test GitHub Packages repository.

在发布包后，您可以在 GitHub 上查看该包。有关详细信息，请参阅“查看包”。

向 GitHub Packages 验证。有关详细信息，请参阅“向 GitHub Packages 进行身份验证”。
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.

向 GitHub Packages 验证。有关详细信息，请参阅“向 GitHub Packages 进行身份验证”。
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")
        }
    }
}
