Gradle UploadArchives SourceCode

Introduction

In software development, it is often necessary to share our code libraries or artifacts with others. One common way to achieve this is by publishing our code to a repository, such as Maven or Ivy, so that others can easily consume our code as dependencies in their projects.

In the Gradle build system, the uploadArchives task allows us to publish our code artifacts to a repository. In this article, we will explore how to use uploadArchives to publish our source code to a repository.

Prerequisites

Before we can use the uploadArchives task, we need to configure our Gradle build script properly. Here is an example of a basic build script:

plugins {
    id 'java'
}

group = 'com.example'
version = '1.0.0'

repositories {
    mavenCentral()
}

dependencies {
    // dependencies for our project
}

uploadArchives {
    repositories {
        mavenDeployer {
            repository(url: "file://${project.buildDir}/repo")
        }
    }
}

In this example, we have defined our project's group and version, added a repository, and specified the uploadArchives task to publish to a local directory.

Publishing Source Code

To publish our source code along with our artifacts, we need to include the following steps in our Gradle build script:

1. Enable the generation of source code JAR file. Add the following code to the build script:

   jar {
       from sourceSets.main.allSource
   }
   

   This ensures that a JAR file containing our source code is generated during the build process.

2. Configure the uploadArchives task to publish the source code JAR file. Modify the uploadArchives task as follows:

   uploadArchives {
       repositories {
           mavenDeployer {
               repository(url: "file://${project.buildDir}/repo")
   
               addFilter('sources') {
                   artifact = file("${project.buildDir}/libs/${project.name}-sources.jar")
               }
           }
       }
   }
   

   Here, we have added a filter named 'sources' and specified the path to the source code JAR file. This tells Gradle to publish the source code JAR file along with the other artifacts.

3. Run the uploadArchives task. Open a terminal or command prompt, navigate to the project directory, and execute the following command:

   ./gradlew uploadArchives
   

   This will build the project and publish the artifacts, including the source code, to the specified repository.

Conclusion

In this article, we have explored how to use the uploadArchives task in Gradle to publish our source code to a repository. By following the steps outlined in this article, you can easily share your code libraries or artifacts with others, allowing them to consume your code as dependencies in their projects.

Remember to configure your Gradle build script properly, enable the generation of source code JAR file, and configure the uploadArchives task to publish the source code alongside other artifacts. With these steps in place, you can easily publish your source code and make it available for others to use.
