Gradle (Groovy)

Publish a package

The following steps describe the process above:

1. Copy the following Gradle (Groovy) snippet, paste it into your build.gradle file, and modify accordingly:

   plugins {
       id 'java'          // To publish java libraries
       id 'maven-publish' // To publish to Maven repositories
   }
   
   // Download standard plugins, e.g., maven-publish  from GradlePluginPortal
   repositories {
     gradlePluginPortal()
   }
   
   // Define Maven repository to publish to
   publishing {
     publications {
       maven(MavenPublication) {
   
         // MODIFY: Define your Maven coordinates of your package
         groupId = "com.name.domain.my"
         artifactId = "my-java-package-name"
         version = "my-java-package-version"
   
         // Tell gradle to publish project's jar archive
         from components.java
       }
     }
   
     repositories {
       maven {
         // Define the Buildkite repository to publish to
         url "https://packages.buildkite.com/{org.slug}/{registry.slug}/maven2/"
         authentication {
           header(HttpHeaderAuthentication)
         }
         credentials(HttpHeaderCredentials) {
           name = "Authorization"
           value = "Bearer registry-write-token"
         }
       }
     }
   }
   

   where:

   • registry-write-token is your API access token used to publish/upload packages to your Java source registry. Ensure this access token has the Read Packages and Write Packages REST API scopes, which allows this token to publish packages to any source registry your user account has access to within your Buildkite organization.

   • com.name.domain.my is the domain name of your Java package (in typical right-to-left order).

   • my-java-package-name is the name of your Java package.

   • my-java-package-version is the version number of your Java package.

   • {org.slug} can be obtained from the end of your Buildkite URL, after accessing Package Registries or Pipelines in the global navigation of your organization in Buildkite.
   • {registry.slug} is the slug of your Java source registry, which is the kebab-case version of this registry's name, and can be obtained after accessing Package Registries in the global navigation > your Java source registry from the Registries page.

2. Publish your package:

   gradle publish
   

Access a package's details

A Java package's details can be accessed from its source registry through the Releases (tab) section of your Java source registry page. To do this:

1. Select Package Registries in the global navigation to access the Registries page.
2. Select your Java source registry on this page.
3. On your Java source registry page, select the package to display its details page.

The package's details page provides the following information in the following sections:

• Installation (tab): the installation instructions.
• Contents (tab, where available): a list of directories and files contained within the package.
• Details (tab): a list of checksum values for this package—MD5, SHA1, SHA256, and SHA512.
• About this version: a brief (metadata) description about the package.

• Details: details about:

  • the name of the package (typically the file name excluding any version details and extension).
  • the package version.
  • the source registry the package is located in.
  • the package's visibility (based on its registry's visibility)—whether the package is Private and requires authentication to access, or is publicly accessible.
  • the distribution name / version.
  • additional optional metadata contained within the package, such as a homepage, licenses, etc.

• Pushed: the date when the last package was uploaded to the source registry.

• Total files: the total number of files (and directories) within the package.

• Dependencies: the number of dependency packages required by this package.

• Package size: the storage size (in bytes) of this package.

• Downloads: the number of times this package has been downloaded.

Downloading a package

A Java package can be downloaded from the package's details page. To do this:

1. Access the package's details.
2. Select Download.

Installing a package

A Java package can be installed using code snippet details provided on the package's details page. To do this:

1. Access the package's details.
2. Ensure the Installation tab is displayed and select the Gradle (Groovy) section to expand it.
3. Copy the code snippet, paste this into the build.gradle Gradle file, and run gradle install on this modified script file to install this package.

This code snippet is based on this format:

repositories {
  maven {
    url "https://packages.buildkite.com/{org.slug}/{registry.slug}/maven2/"
    authentication {
      header(HttpHeaderAuthentication)
    }
    credentials(HttpHeaderCredentials) {
      name = "Authorization"
      value = "Bearer registry-read-token"
    }
  }
}

dependencies {
  implementation "com.name.domain.my:my-java-package-name:my-java-package-version"
}

where:

• {org.slug} can be obtained from the end of your Buildkite URL, after accessing Package Registries or Pipelines in the global navigation of your organization in Buildkite.

• {registry.slug} is the slug of your registry, which is the kebab-case version of your registry name, and can be obtained after accessing Package Registries in the global navigation > your registry from the Registries page.

• registry-read-token is your API access token or registry token used to download packages from your Java registry. Ensure this access token has the Read Packages REST API scope, which allows this token to download packages from any registry your user account has access to within your Buildkite organization.

  Note: Both the authentication and credentials sections are not required for registries that are publicly accessible.

• com.name.domain.my is the domain name of your Java package (in typical right-to-left order).

• my-java-package-name is the name of your Java package.

• my-java-package-version is the version number of your Java package.
