To reproduce, create a secret in Secrets Manager by the name "AmazonMQCredentials" and create some secret inside it, eg. user = admin

Then run the above code.

Expected Behavior

Code should run and print out the value of the secret from Secrets Manager

You don't even have to use my modified code to see the issue. Just take the code generated by Secrets Manager as-is and try running it. You will run into this error

// Use this code snippet in your app.
// If you need more information about configurations or implementing the sample
// code, visit the AWS docs:
// https://docs.aws.amazon.com/sdk-for-java/latest/developer-guide/home.html

// Make sure to import the following packages in your code
// import software.amazon.awssdk.regions.Region;
// import software.amazon.awssdk.services.secretsmanager.SecretsManagerClient;
// import software.amazon.awssdk.services.secretsmanager.model.GetSecretValueRequest;
// import software.amazon.awssdk.services.secretsmanager.model.GetSecretValueResponse;

public static void getSecret() {

String secretName = "AmazonMQCredentials";
Region region = Region.of("us-west-2");

// Create a Secrets Manager client
SecretsManagerClient client = SecretsManagerClient.builder()
        .region(region)
        .build();

GetSecretValueRequest getSecretValueRequest = GetSecretValueRequest.builder()
        .secretId(secretName)
        .build();

GetSecretValueResponse getSecretValueResponse;

try {
    getSecretValueResponse = client.getSecretValue(getSecretValueRequest);
} catch (Exception e) {
    // For a list of exceptions thrown, see
    // https://docs.aws.amazon.com/secretsmanager/latest/apireference/API_GetSecretValue.html
    throw e;
}

String secret = getSecretValueResponse.secretString();

// Your code goes here.

NoClassDefFoundError indicates that a class could not be loaded at runtime. This is usually caused by using different versions of the SDK core and service modules. Ideally, all SDK modules should be in the same version.

Looking at your pom.xml, you are using different versions for different SDK modules, this is probably the root cause:
software.amazon.awssdk:regions 2.4.3
software.amazon.awssdk:secretsmanager 2.15.80
software.amazon.awssdk:utils 2.10.49

We recommend using the BOM artifact to avoid this problem, check more info in our Dev Guide - https://docs.aws.amazon.com/sdk-for-java/latest/developer-guide/setup-project-maven.html#sdk-as-dependency

OK. After using the BOM, it worked. Thanks. Closing the issue
