java.lang.ClassNotFoundException: com.amazonaws.transform.EnhancedJsonErrorUnmarshaller

Question

When trying to connect to the secret manager my code is throwing this exception. I am trying to Create a Secrets Manager client.

AWSSecretsManager client = 
    AWSSecretsManagerClientBuilder.standard()
        .withRegion(region)
        .build();

In Pom.xml have added the following dependencies.

<dependency>
    <groupId>com.amazonaws</groupId>
    <artifactId>aws-java-sdk-secretsmanager</artifactId>
    <version>1.11.965</version>
</dependency>
<dependency>
    <groupId>com.amazonaws</groupId>
    <artifactId>aws-java-sdk</artifactId>
    <version>1.11.965</version>
</dependency>

    <groupId>com.amazonaws</groupId>
    <artifactId>aws-java-sdk-core</artifactId>
    <version>1.11.965</version>
</dependency>

Amazon suggests moving to the AWS SDK for Java V2. You can find Secret Manager V2 code in Github here.

The POM file that contains the dependencies is located in Github in the SecretManager folder.

V2 code has been tested many times and this code works:

package com.example.secrets;

//snippet-start:[secretsmanager.java2.create_secret.import]
import software.amazon.awssdk.regions.Region;
import software.amazon.awssdk.services.secretsmanager.SecretsManagerClient;
import software.amazon.awssdk.services.secretsmanager.model.CreateSecretRequest;
import software.amazon.awssdk.services.secretsmanager.model.CreateSecretResponse;
import software.amazon.awssdk.services.secretsmanager.model.SecretsManagerException;
//snippet-end:[secretsmanager.java2.create_secret.import]

public class CreateSecret {

    public static void main(String[] args) {

       final String USAGE = "\n" +
                "Usage:\n" +
                "    CreateSecret  <secretName> <secretValue> \n\n" +
                "Where:\n" +
                "    secretName - the name of the secret (for example, tutorials/MyFirstSecret). \n"+
                "    secretValue - the secret value. \n";

        if (args.length != 2) {
            System.out.println(USAGE);
            System.exit(1);
        }

       String secretARN = createNewSecret(secretsClient, secretName, secretValue);
       System.out.println("The secret ARN is "+ secretARN);
       secretsClient.close();
    }

                .secretString(secretValue)
                .build();

            CreateSecretResponse secretResponse = secretsClient.createSecret(secretRequest);
            return secretResponse.arn();

        } catch (SecretsManagerException e) {
            System.err.println(e.awsErrorDetails().errorMessage());
            System.exit(1);
        }
        return "";
