AmazonS3Client depreciado

olá, galera!

Estou tentando simular o Amazon S3 localmente com o Ninja S3 (s3ninja.net/). Implementando sessa forma deu certo:

import com.amazonaws.auth.AWSCredentials;
import com.amazonaws.services.s3.AmazonS3;
import com.amazonaws.services.s3.AmazonS3Client;
 
public void test01() {
			
	final String ID = "AKIAIOSFODNN7EXAMPLE";
	final String KEY ="wJalrXUtnFEMI/K7MDENG/bPxRfiCYEXAMPLEKEY";
	final String NINJA_URL = "http://localhost:9444/s3";	
		
	AWSCredentials credentials = new BasicAWSCredentials(ID, KEY);
	AmazonS3 s3client = new AmazonS3Client(credentials, new ClientConfiguration());
    s3client.setEndpoint(NINJA_URL);							
	//lista os buckets
	System.out.println(s3client.listBuckets());
}

Porém atualizando para a ultima versão do SDK da AmazonAWS, que é o 1.11.222, a chamada new AmazonS3Client() está depreciada. Olhando a API na última versão, tentei adequar o código dessa forma:

 public void test01() {

    final String ID = "AKIAIOSFODNN7EXAMPLE";
	final String KEY ="wJalrXUtnFEMI/K7MDENG/bPxRfiCYEXAMPLEKEY";
	final String NINJA_URL = "http://localhost:9444/s3";	
	
	BasicAWSCredentials creds = new BasicAWSCredentials(ID, KEY);		
	AmazonS3 s3client = AmazonS3ClientBuilder.standard().withCredentials(new AWSStaticCredentialsProvider(creds)).build();  // com.amazonaws.SdkClientException  aqui
	
	s3client.setEndpoint(NINJA_URL);
	
	System.out.println(s3client.listBuckets());
}

Mas na linha estou obtendo a execeção:

         com.amazonaws.SdkClientException: Unable to find a region via the region provider chain. Must provide an explicit 
region in the builder or setup environment to supply a region.
at com.amazonaws.client.builder.AwsClientBuilder.setRegion(AwsClientBuilder.java:371)

at main.Main01.test01(Main01.java:37)

Alguém sabe como poderia resolver esse erro?
obrigado
