Localstack java.lang.NoClassDefFoundError: com/amazonaws/auth/AWSCredentials

Question

I would like to make some testes using localstack (SQS) in Spring Boot with a local docker container, so i'm using the LocalStackContainer to talk to my local docker container, but when i run the tests a weird exceptions happens. First i will show the code and second the stack trace.

The code: here i try to make a connection to the local docker with the image of localstack v 0.11.6 and SQS as the service. In this line, i got the exception.

import org.testcontainers.containers.localstack.LocalStackContainer;
import org.testcontainers.utility.DockerImageName;

@SpringBootTest(classes = SqsConsumer.class)
public class SqsConsumerTest {

    public static LocalStackContainer localStackContainer = new LocalStackContainer(DockerImageName.parse("localstack/localstack:0.11.6"))
            .withServices(LocalStackContainer.Service.SQS);

    @BeforeClass
    public static void initLocalStack() throws IOException, InterruptedException {
        localStackContainer.start();

        localStackContainer.execInContainer("awslocal", "sqs", "create-queue", "--queue-name", "image-sqs");
    }

}

the Exception/Stacktrace:

java.lang.NoClassDefFoundError: com/amazonaws/auth/AWSCredentials

Well, the dependencies:

<dependency>
        <groupId>software.amazon.awssdk</groupId>
        <artifactId>sqs</artifactId>
    </dependency>

    <dependency>
        <groupId>software.amazon.awssdk</groupId>

        <groupId>org.testcontainers</groupId>
        <artifactId>testcontainers</artifactId>
        <scope>test</scope>
    </dependency>

I've already checked the running docker container and i think everthing is ok from there. Its kind of weird this problem, i've checked the dependencies and its likely to be the problem but i didn't found any valid dependency for that.

EDIT: After using another dependency from maven, it worked. Thanks everybody.

<dependency>
    <groupId>com.amazonaws</groupId>
    <artifactId>aws-java-sdk-sqs</artifactId>
    <version>1.12.142</version>
</dependency>

Try adding the following dependency:

<dependency>
    <groupId>com.amazonaws</groupId>
    <artifactId>aws-java-sdk-sqs</artifactId>
    <version>1.12.142</version>
</dependency>

Probably related to this question: JUnit AWSCredentials NoClassDefFoundError with LocalStackContainer

Edit: changed the artifact id to aws-java-sdk-sqs from aws-java-sdk-s3

In my case I'm using SQS but after searching in maven i found this out and it worked. ` com.amazonaws aws-java-sdk-sqs 1.12.142 ` – Victor Hugo Pongolino Jan 19 '22 at 17:26
Oh right, my bad. I'll update the answer for future reference. – cakedmypants Jan 19 '22 at 18:27
