Gradle

Buildkite Packages provides repository support for Gradle-based packages for Java using the Maven Publish Plugin.

Once your Java (Gradle) package repository has been created, you can upload packages (generated from your application's build) to this repository by configuring your application's relevant build.gradle file presented on your Java (Gradle) package repository's details page.

To view and copy the required build.gradle configurations:

Select Packages in the global navigation to access the Repositories page.
Select your Java (Gradle) package repository on this page.
Expand Publishing a package section and in the Using Gradle with maven-publish plugin section, use the copy icon at the top-right of the code box to copy the Gradle code snippet and paste it into the appropriate area/s of your build.gradle file.

These build.gradle file configurations contain the Maven coordinates for your package (which you will need to manually configure yourself), the URL for your specific Java (Gradle) package repository in Buildkite, and authentication credentials (generated by Buildkite Packages) required to upload the package to this repository.

Publish a package

The following steps describe the process above:

Copy, paste and modify the following Gradle snippet in your gradle.build file:

// You require these plugins
// "java": To publish java libraries
// "maven-publish": To publish to Maven repositories
["java", "maven-publish"].each {
    apply plugin : it
}

// Donwload 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.your_domain_name"
      artifactId = "your_package_name"
      version = "your_package_version"

      // Tell gradle to publish project's jar archive
      from components.java
    }
  }

  repositories {
    maven {
      // Define the Buildkite repository to publish to
      url "https://buildkitepackages.com/{org.slug}/{java.gradle.package.repository.name}/java/maven2/"
      credentials {
        username = "java-gradle-package-repository-credentials"
        password = ""
      }
    }
  }
}

Publish your package:
```
gradle publish
```
