You must publish a package to a project, but note which endpoint -you use to install the package. The option you choose determines the settings you add to your `pom.xml` file for publishing. - -The three endpoints are: - -- **Project-level**: Use when you have a few Maven packages that are not in the same GitLab group. -- **Group-level**: Use when installing packages from many different projects in the same GitLab group. GitLab does not guarantee the uniqueness of package names in the group. You can have two projects with the same package name and package version. As a result, GitLab serves whichever one is more recent. -- **Instance-level**: Use when installing many packages from different GitLab groups or in their own namespace. - -**Only packages with the same path as the project** are exposed by the instance-level endpoint. - -| Project | Package | Instance-level endpoint available | -| ------------------- | -------------------------------- | --------------------------------- | -| `foo/bar` | `foo/bar/1.0-SNAPSHOT` | Yes | -| `gitlab-org/gitlab` | `foo/bar/1.0-SNAPSHOT` | No | -| `gitlab-org/gitlab` | `gitlab-org/gitlab/1.0-SNAPSHOT` | Yes | - -#### Endpoint URLs - -| Endpoint | Endpoint URL | Additional information | -| -------- | ------------------------------------------------------------------------ | ---------------------------------------------------------------------------------------------------------------------------------- | -| Project | `https://gitlab.example.com/api/v4/projects/<project_id>/packages/maven` | Replace `gitlab.example.com` with your domain name.

Add a `publishing` section: - - In Groovy DSL: - - ```groovy - publishing { - publications { - library(MavenPublication) { - from components.java - } - } - repositories { - maven { - url "https://gitlab.example.com/api/v4/projects/<PROJECT_ID>/packages/maven" - credentials(HttpHeaderCredentials) { - name = "REPLACE_WITH_TOKEN_NAME" - value = gitLabPrivateToken // the variable resides in $GRADLE_USER_HOME/gradle.properties - } - authentication { - header(HttpHeaderAuthentication) - } - } - } - } - ``` - - In Kotlin DSL: - - ```kotlin - publishing { - publications { - create<MavenPublication>("library") { - from(components["java"]) - } - } - repositories { - maven { - url = uri("https://gitlab.example.com/api/v4/projects/<PROJECT_ID>/packages/maven") - credentials(HttpHeaderCredentials::class) { - name = "REPLACE_WITH_TOKEN_NAME" - value = - findProperty("gitLabPrivateToken") as String? // the variable resides in $GRADLE_USER_HOME/gradle.properties - } - authentication { - create("header", HttpHeaderAuthentication::class) - } - } - } - } - ``` - -1. Replace `PROJECT_ID` with your project ID, which you can find on your project's home page. - -1. Run the publish task: - - ```shell - gradle publish - ``` - -Go to your project's **Packages and registries** page and view the published packages. - -## Install a package - -To install a package from the GitLab Package Registry, you must configure -the [remote and authenticate](#authenticate-to-the-package-registry-with-gradle). -After configuring the remote and authenticate, you can install a package from a project, group, or namespace. - -If multiple packages have the same name and version, when you install -a package, the most recently-published package is retrieved. - -Add a [dependency](https://docs.gradle.org/current/userguide/declaring_dependencies.html) to `build.gradle` in the dependencies section: - -```groovy -dependencies { - implementation 'com.mycompany.mydepartment:my-project:1.0-SNAPSHOT' -} -``` - -Or to `build.gradle.kts` if you are using Kotlin DSL: - -```kotlin -dependencies { - implementation("com.mycompany.mydepartment:my-project:1.0-SNAPSHOT") -} -``` - -## Helpful hints - -For the complete list of helpful hints, see the [Maven documentation](../maven_repository/index.md#helpful-hints). - -### Create Maven packages with GitLab CI/CD by using Gradle - -You can create a package each time the `main` branch -is updated. - -1. Authenticate with [a CI job token in Gradle](#authenticate-with-a-ci-job-token-in-gradle). - -1. Add a `deploy` job to your `.gitlab-ci.yml` file: - - ```yaml - deploy: - image: gradle:6.5-jdk11 - script: - - 'gradle publish' - only: - - main - ``` - -1. Commit files to your repository. - -When the pipeline is successful, the Maven package is created. - -### Publishing a package with the same name or version - -When you publish a package with the same name and version as an existing package, the new package -files are added to the existing package. You can still use the UI or API to access and view the -existing package's older assets. - -Consider using the Packages API or the UI to delete older package versions. - -### Do not allow duplicate Maven packages - -To prevent users from publishing duplicate Maven packages, you can use the [GraphQl API](../../../api/graphql/reference/index.md#packagesettings) or the UI. - -In the UI: - -1. For your group, go to **Settings > Packages and registries**. -1. Expand the **Package Registry** section. -1. Turn on the **Do not allow duplicates** toggle. -1. Optional. To allow some duplicate packages, in the **Exceptions** box, enter a regex pattern that matches the names and/or versions of packages you want to allow. - -Your changes are automatically saved. - -### Request forwarding to Maven Central - -FLAG: -By default, this feature is not available for self-managed. To make it available, ask an administrator to [enable the feature flag](../../../administration/feature_flags.md) named `maven_central_request_forwarding`. -This feature is not available for SaaS users. - -When a Maven package is not found in the Package Registry, the request is forwarded -to [Maven Central](https://search.maven.org/). - -When the feature flag is enabled, administrators can disable this behavior in the -[Continuous Integration settings](../../admin_area/settings/continuous_integration.md). - -There are many ways to configure your Maven project to request packages -in Maven Central from GitLab. Maven repositories are queried in a -[specific order](https://maven.apache.org/guides/mini/guide-multiple-repositories.html#repository-order). -By default, maven-central is usually checked first through the -[Super POM](https://maven.apache.org/guides/introduction/introduction-to-the-pom.html#Super_POM), so -GitLab needs to be configured to be queried before maven-central. - -[Using GitLab as a mirror of the central proxy](../maven_repository/index.md#setting-gitlab-as-a-mirror-for-the-central-proxy) is one -way to force GitLab to be queried in place of maven-central. - -Maven forwarding is restricted to only the project level and -group level [endpoints](#naming-convention). The instance-level endpoint -has naming restrictions that prevent it from being used for packages that don't follow that convention and also -introduces too much security risk for supply-chain style attacks. +<!-- This redirect file can be deleted after <2023-08-09>. --> +<!-- Redirects that point to other docs in the same project expire in three months. --> +<!-- Redirects that point to docs in a different project or site (for example, link is not relative and starts with `https:`) expire in one year. --> +<!-- Before deletion, see: https://docs.gitlab.com/ee/development/documentation/redirects.html --> |
