What to do when getting 'software.amazon.awssdk.services.s3 does not exist' error in Maven project?

I am trying to make a Create Bucket program using the aws s3 sdk, but this error stops the compilation:java: package software.amazon.awssdk.services.s3 does not exist

This is the pom.xml:

    </dependencies>

</project>

This is the CreateBucketExample.java:

package org.example;

import software.amazon.awssdk.services.s3.S3Client;

public class CreateBucketExample {
    public static void main(String[] args) {
        String bucketName = "bucket4example";
        S3Client client = S3Client.builder().build();

        CreateBucketRequest request = CreateBucketRequest.builder().bucket(bucketName).build();

        client.createBucket(request);


    }
}

This was the code from my previous work, but a similar import problem arose:

package aws.example.s3;

import com.amazonaws.regions.Regions;
import com.amazonaws.services.s3.AmazonS3;
import com.amazonaws.services.s3.AmazonS3ClientBuilder;
import com.amazonaws.services.s3.model.AmazonS3Exception;
import com.amazonaws.services.s3.model.Bucket;

Any suggestions would be appreciated. Thanks

Solution

  • Your Amazon S3 code looks fine. I have never had an issue running S3 code when POM is set properly. I used JDK 17 and my code worked.

    enter image description here

    My Java code uses Waiters which is the only difference from your code. I think your issue is your POM.

    Java code

    import software.amazon.awssdk.auth.credentials.ProfileCredentialsProvider;
import software.amazon.awssdk.core.waiters.WaiterResponse;
import software.amazon.awssdk.regions.Region;
import software.amazon.awssdk.services.s3.S3Client;
import software.amazon.awssdk.services.s3.model.CreateBucketRequest;
import software.amazon.awssdk.services.s3.model.HeadBucketRequest;
import software.amazon.awssdk.services.s3.model.HeadBucketResponse;
import software.amazon.awssdk.services.s3.model.S3Exception;
import software.amazon.awssdk.services.s3.waiters.S3Waiter;
import java.net.URISyntaxException;

public class HelloS3 {

    public static void main(String[] args) throws URISyntaxException {

        String bucketName = "myjunebucket";
        System.out.format("Creating a bucket named %s\n", bucketName);
        ProfileCredentialsProvider credentialsProvider = ProfileCredentialsProvider.create();
        Region region = Region.US_EAST_1;
        S3Client s3 = S3Client.builder()
            .region(region)
            .credentialsProvider(credentialsProvider)
            .build();

        createBucket (s3, bucketName);
        s3.close();
    }
    public static void createBucket( S3Client s3Client, String bucketName) {
        try {
            S3Waiter s3Waiter = s3Client.waiter();
            CreateBucketRequest bucketRequest = CreateBucketRequest.builder()
                .bucket(bucketName)
                .build();

            s3Client.createBucket(bucketRequest);
            HeadBucketRequest bucketRequestWait = HeadBucketRequest.builder()
                .bucket(bucketName)
                .build();

            // Wait until the bucket is created and print out the response.
            WaiterResponse<HeadBucketResponse> waiterResponse = s3Waiter.waitUntilBucketExists(bucketRequestWait);
            waiterResponse.matched().response().ifPresent(System.out::println);
            System.out.println(bucketName +" is ready");

        } catch (S3Exception e) {
            System.err.println(e.awsErrorDetails().errorMessage());
            System.exit(1);
        }
    }
}
