Managing Dependencies in Gradle with AWS SDK for Java – Bill of Materials module (BOM)

In an earlier blog post, I discussed how a Maven bill of materials (BOM) module can be used to manage your Maven dependencies on the AWS SDK for Java.

In this blog post, I will provide an example of how you can use the Maven BOM in your Gradle projects to manage the dependencies on the SDK. I will use an open source Gradle dependency management plugin from Spring to import a BOM and then use its dependency management.

Here is the build.gradle snippet to apply the dependency management plugin to the project:

buildscript {
    repositories {
        mavenCentral()
    }
    dependencies {
        classpath "io.spring.gradle:dependency-management-plugin:0.5.4.RELEASE"
    }
}

apply plugin: "io.spring.dependency-management"

Now, import the Maven BOM into the dependencyManagement section and specify the SDK modules in the dependencies section, as shown here:

dependencyManagement {
    imports {
        mavenBom 'com.amazonaws:aws-java-sdk-bom:1.10.47'
    }
}

dependencies {
    compile 'com.amazonaws:aws-java-sdk-s3'
    testCompile group: 'junit', name: 'junit', version: '4.11'
}

Gradle resolves the aws-java-sdk-s3 module to the version specified in the BOM, as shown in the following dependency resolution diagram.
