AWS SDK for Java 2.0
The AWS SDK for Java 2.0 is a rewrite of 1.0 with some great new features. As with version 1.0,
it enables you to easily work with Amazon Web Services but also includes features like
non-blocking IO and pluggable HTTP implementation to further customize your applications. You can
get started in minutes using Maven or any build system that supports MavenCentral as an
artifact source.

Getting Started
Sign up for AWS
Before you begin, you need an AWS account. Please see the Sign Up for AWS section of
the developer guide for information about how to create an AWS account and retrieve your AWS
credentials.
Minimum requirements
To run the SDK 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.
Using the SDK
The recommended way to use the AWS SDK for Java in your project is to consume it from Maven.
Importing the BOM
To automatically manage module versions (currently all modules have the same version, but this may not always be the case) we recommend you use the Bill of Materials import as follows:
<dependencyManagement>
<dependencies>
<dependency>
<groupId>software.amazon.awssdk</groupId>
<artifactId>bom</artifactId>
<version>2.10.56</version>
<type>pom</type>
<scope>import</scope>
</dependency>
</dependencies>
</dependencyManagement>
Then individual models may omit the version from their dependency statement:
<dependencies>
<dependency>
<groupId>software.amazon.awssdk</groupId>
<artifactId>ec2</artifactId>
</dependency>
<dependency>
<groupId>software.amazon.awssdk</groupId>
<artifactId>s3</artifactId>
</dependency>
<dependency>
<groupId>software.amazon.awssdk</groupId>
<artifactId>dynamodb</artifactId>
</dependency>
</dependencies>
Individual Services
Alternatively you can add dependencies for the specific services you use only:
<dependency>
<groupId>software.amazon.awssdk</groupId>
<artifactId>ec2</artifactId>
<version>2.10.56</version>
</dependency>
<dependency>
<groupId>software.amazon.awssdk</groupId>
<artifactId>s3</artifactId>
<version>2.10.56</version>
</dependency>
Whole SDK
You can import the whole SDK into your project (includes ALL services). Please note that it is recommended to only import the modules you need.
<dependency>
<groupId>software.amazon.awssdk</groupId>
<artifactId>aws-sdk-java</artifactId>
<version>2.10.56</version>
</dependency>
See the Set up the AWS SDK for Java section of the developer guide for more usage information.
New Features for 2.0
-
Provides a way to plug in your own HTTP implementation.
-
Provides first class support for non-blocking IO in Async clients.
Building From Source
Once you check out the code from GitHub, you can build it using Maven.
mvn clean install
# Skip tests, checkstyles, findbugs, etc for quick build
mvn clean install -P quick
# Build a specific service module
mvn clean install -pl :s3 -P quick --am
Sample Code
You can find sample code for v2 in the following places:
- aws-doc-sdk-examples repo.
- Integration tests in this repo. They are located in the
itdirectory under each service module, eg: s3-integration-tests
