</project>

Above is my pom.xml file And the following is my Java Code

import com.amazonaws.regions.Regions;
import com.amazonaws.services.sns.AmazonSNS;
import com.amazonaws.services.sns.AmazonSNSClient;
import com.amazonaws.services.sns.model.MessageAttributeValue;
import com.amazonaws.services.sns.model.PublishRequest;
import com.amazonaws.services.sns.model.PublishResult;

import java.util.HashMap;
import java.util.Map;

public class AwsSNSClient
{
    public static final String AWS_ACCESS_KEY_ID = "aws.accessKeyId";
    public static final String AWS_ACCESS_KEY = "aws.secretKey";
    static
    {
        System.setProperty(AWS_ACCESS_KEY_ID,"xxx");
        System.setProperty(AWS_ACCESS_KEY,"yyy");
    }
    public static void main(String args[])
    {
        AwsSNSClient myClient = new AwsSNSClient();
        myClient.sendSingleSMS("This is a message sent from PC from MAVEN CLI","+91xxx");
    }
    public void sendSingleSMS(String message,String phoneNumber)
    {
        AmazonSNS snsClient = AmazonSNSClient.builder().withRegion(Regions.AP_SOUTH_1).build();
        Map<String, MessageAttributeValue> smsAttributes = new HashMap<String, MessageAttributeValue>();
        smsAttributes.put("AWS.SNS.SMS.SenderID", new MessageAttributeValue().withStringValue("MyWebsite").withDataType("String"));
        smsAttributes.put("AWS.SNS.SMS.SMSType", new MessageAttributeValue().withStringValue("Transactional").withDataType("String"));

        PublishResult result = snsClient.publish(new PublishRequest()
                .withMessage(message)
                .withPhoneNumber(phoneNumber)
                .withMessageAttributes(smsAttributes));

        System.out.println("Message Sent Successfully---"+result.getMessageId());
    }
}

And here is the Exception generated in my Command Line
