I'm migrating AWS SDK for java from v1 to v2. Earlier I was instantiating the AWSIotMqttClient like

Credentials cred = awsService.generateTempIAMCredentialsForIOT();

// AWS IAM credentials could be retrieved from AWS Cognito, STS etc.
IOTMqttClient client = new IOTMqttClient(iotEndpoint, clientId, cred.accessKeyId(),
    cred.secretAccessKey(), cred.sessionToken(), this);

the sdk-v2 doesn't seem to have any way to use IAM credentials for MqttClientConnection or Mqtt5Client.

Does anyone know a possible way to accomplish this via sdk-v2?

Thanks

• Show your pom.xml , or build.gralde, and version of Java, etc. Let's show full content of Java class , before go to your problem. We need context of your problem first. – Vy Do Commented Apr 2 at 8:25

AWS SDK in general has a good way for looking for configuration with minimal intervention / configuration from the developer, as long as you make sure you have the necessary configuration in place, either it's giving necessary IAM Policy access or having temporary credentials placed in a config file.

Please have a deep dive into

https://docs.aws.amazon/sdk-for-java/latest/developer-guide/credentials.html

Which basically suggests you don't need to specify anything if you assign the right policy to the resource you are running your code at.
