Question

Im trying to write the JAVA code to get the cloud front distribution details using AWS JAVA SDK 1.x

below is the code snippet

public static void main(String[] args) {
        // TODO Auto-generated method stub
  final AmazonCloudFront cf = AmazonCloudFrontClientBuilder.standard().withRegion("us-east-1").build();
          GetDistributionRequest rq = new GetDistributionRequest();
           System.out.println( cf.getDistribution(rq).getDistribution());
  }

getting below exception

20:48:07.002 [main] DEBUG com.amazonaws.AmazonWebServiceClient - Internal logging successfully configured to commons logger: true
20:48:07.347 [main] DEBUG com.amazonaws.monitoring.CsmConfigurationProviderChain - Unable to load configuration from com.amazonaws.monitoring.EnvironmentVariableCsmConfigurationProvider@5a85c92: Unable to load Client Side Monitoring configurations from environment variables!

what Im not able to understand is which Id code is looking for?

My findings:

1. There is no any AWS authentication issue. I confirmed this because S3 AWS SDK works fine.

2. I referred many blogs and AWS docs, havent found any sample code for 1.x

below is the pom.xml snippet

<dependency>
    <groupId>com.amazonaws</groupId>
    <artifactId>aws-java-sdk-cloudfront</artifactId>
    <version>1.12.781</version>
</dependency>

Environment details:

JAVA: 17

not sure what is missing.
