Step-by-step instructions

Consuming IoT Device SDK from Maven in your application

Consuming this SDK via Maven is the preferred method of consuming it and using it within your application. To consume the Java V2 SDK in your application, add the following to your pom.xml dependencies:

<dependency>
  <groupId>software.amazon.awssdk.iotdevicesdk</groupId>
  <artifactId>aws-iot-device-sdk</artifactId>
  <version>1.21.0</version>
</dependency>

Replace 1.21.0 in <version>1.21.0</version> with the latest release version for the SDK. Look up the latest SDK version here: https://github.com/aws/aws-iot-device-sdk-java-v2/releases

Build IoT Device SDK from source

Install Maven and Set PATH

# Create a workspace directory to hold all the SDK files
mkdir sdk-workspace
cd sdk-workspace
# Clone the repository
git clone https://github.com/awslabs/aws-iot-device-sdk-java-v2.git
cd aws-iot-device-sdk-java-v2
# Compile and install
mvn clean install

If you wish to use the latest CRT release, rather than the latest tested with the IoT SDK, you can run the following before running mvn clean install:

# Update the version of the CRT being used
mvn versions:use-latest-versions -Dincludes="software.amazon.awssdk.crt*"

Mac-Only TLS Behavior

Please note that on Mac, once a private key is used with a certificate, that certificate-key pair is imported into the Mac Keychain. All subsequent uses of that certificate will use the stored private key and ignore anything passed in programmatically. Beginning in v1.7.3, when a stored private key from the Keychain is used, the following will be logged at the "info" log level:

static: certificate has an existing certificate-key pair that was previously imported into the Keychain.  Using key from Keychain instead of the one provided.
