The AWS SDK for Java enables Java developers to easily work with Amazon Web Services and build scalable solutions with Amazon S3, Amazon DynamoDB, Amazon Glacier, and more.

See the AWS SDK for Java 2.x for how to get started.

The AWS SDK for Java 1.x reached end-of-support on December 31, 2025. The SDK no longer receives updates or releases. Previously published releases will continue to be available via public package managers and the code will remain on GitHub.

We recommend that you migrate to the AWS SDK for Java 2.x. The AWS SDK for Java 2.x provides improved features, enhanced performance, and continued support from AWS. By adopting the latest version of the SDK, developers can ensure the security, compatibility, and stability of their solutions on AWS. Updating also allows you to leverage the latest services and innovations from AWS.

Changes to the SDK beginning with version 1.12.1 (June 2021) are tracked in CHANGELOG.md.

Changes in the retired 1.11.x series of the SDK, beginning with version 1.11.82, are listed in the CHANGELOG-1.11.x.md file.

Use the AWS SDK for Java 2.x to get started.

The AWS SDK for Java 1.x is in maintenance mode, so we recommend that you use the AWS SDK for Java 2.x.

To run the AWS SDK for Java 1.x, you will need Java 1.8+. For more information about the requirements and optimum settings for the SDK, please see the Installing a Java Development Environment section of the developer guide.

You can use the AWS SDK for Java 1.x in your project by consuming it from Maven. Import the aws-java-sdk-bom and specify the SDK Maven modules that your project needs in the dependencies.

See the Set up the AWS SDK for Java 1.x section of the developer guide for more information about installing the 1.x SDK through other means.

Once you check out the code from GitHub, you can build it using Maven. To disable the GPG-signing in the build, use:

mvn clean install -Dgpg.skip=true

For information about maintenance and support for SDK major versions and their underlying dependencies, see the following in the AWS SDKs and Tools Reference Guide:

• AWS SDKs and Tools Maintenance Policy
• AWS SDKs and Tools Version Support Matrix

A version 2.x of the SDK is generally available. It is a major rewrite of the 1.x code base, built on top of Java 8+ and adds several frequently requested features. These include support for non-blocking I/O, improved start-up performance, automatic iteration over paginated responses and the ability to plug in a different HTTP implementation at run time.

For more information see the AWS SDK for Java 2.x Developer Guide or check the project repository in https://github.com/aws/aws-sdk-java-v2.

The AWS SDK for Java 1.x supports Java versions from 8 to 17, but may not be updated to support future Java versions. To ensure long-term compatibility with the latest JDK versions, we recommend that you migrate to the AWS SDK for Java 2.x.
