How do you set the maven artifact ID of a Gradle project?

Setting the Maven artifact ID in a Gradle project typically involves editing the build.gradle file. The Maven artifact ID is primarily composed of three parts: group, artifactId, and version, which are referred to as GAV coordinates in Maven. In Gradle, these settings are typically defined within the group, archivesBaseName, and version properties of the build.gradle file.

Here is a simple example illustrating how to set the Maven artifact ID for a Gradle project:

Assuming your project needs to be published to a Maven repository, you can configure it as follows:

1. Open the build.gradle file: First, locate or create a build.gradle file in your project's root directory.

2. Set the artifact's basic information:

   • group: Typically used to define the organization or company's domain in reverse (e.g., com.example).
   • archivesBaseName: This corresponds to Maven's artifactId, defining the basic name of the artifact (e.g., mylibrary).
   • version: Specifies the version number of the artifact (e.g., 1.0.0).

   groovy
   group = 'com.example'
   archivesBaseName = 'mylibrary'
   version = '1.0.0'

3. Apply the Maven plugin: To generate Maven-compatible artifacts, apply the Maven plugin by adding the following line to the build.gradle file:

   groovy
   apply plugin: 'maven'

4. Configure repositories (optional): If you need to publish the artifact to a specific Maven repository, configure repository details in the build.gradle file. For example, to publish to a local Maven repository:

   groovy
   uploadArchives {
       repositories {
           mavenDeployer {
               repository(url: "file://${System.properties['user.home']}/.m2/repository")
           }
       }
   }

By following these steps, your Gradle project is configured with the Maven artifact ID and can generate Maven-compatible packages. This is particularly useful for publishing libraries to the Maven Central Repository or other private repositories. Adjust the values of group, archivesBaseName, and version as needed to align with your project requirements.
