Maven project "AmazonS3ClientBuilder() has private access in com.amazonaws.services.s3.AmazonS3ClientBuilder"

I've got a file and get the error mentioned in the title very early:

import com.amazonaws.services.s3.AmazonS3;
import com.amazonaws.services.s3.AmazonS3Client;
import com.amazonaws.services.s3.AmazonS3ClientBuilder;
import com.amazonaws.services.s3.model.Bucket;
import com.amazonaws.services.s3.model.ObjectMetadata;
import com.amazonaws.services.s3.model.PutObjectRequest;
import com.amazonaws.services.s3.model.PutObjectResult;
import java.io.File;

public static void main(String[] args) throws Exception {
    createAndPopulateSimpleBucket();
}

public static void createAndPopulateSimpleBucket() throws Exception {
    AmazonS3 s3client = new AmazonS3ClientBuilder().standard().build();
}

I get the error in the title when I call new AmazonS3ClientBuilder().

I'm new to Maven, and I think I have my pom set up correctly. Here it is:

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
    <modelVersion>4.0.0</modelVersion>

    <groupId>groupId</groupId>
    <artifactId>AWSJavaHelloWorld</artifactId>
    <version>1.0-SNAPSHOT</version>

    <dependencyManagement>
        <dependencies>
            <dependency>
                <groupId>com.amazonaws</groupId>
                <artifactId>aws-java-sdk-bom</artifactId>
                <version>1.11.715</version>
                <type>pom</type>
                <scope>import</scope>
            </dependency>
        </dependencies>
    </dependencyManagement>

    <dependencies>

        <dependency>
            <groupId>com.amazonaws</groupId>
            <artifactId>aws-java-sdk-s3</artifactId>
        </dependency>

    </dependencies>
</project>

I'm guessing something is wrong with my pom, but I can't figure out what. I also get the same error when I include everything from the AWS SDK (instead of only really including the S3 dependency).

So, can anyone spot what's wrong?

The documentation of AmazonS3ClientBuilder states that this class does not expose a public no-arg constructor. This means that you cannot invoke new AmazonS3ClientBuilder() from your class.

Fortunately, this class provides two static factory methods; one of these methods, AmazonS3ClientBuilder#defaultClient, creates an AmazonS3 instance (the client), and the other method, AmazonS3ClientBuilder#standard, creates an instance of the builder.

Knowing this, you can replace your code with one of the following snippets:

public static void createAndPopulateSimpleBucket() throws Exception {
    AmazonS3 s3client = AmazonS3ClientBuilder.defaultClient();
}

Or:

public static void createAndPopulateSimpleBucket() throws Exception {
    AmazonS3 s3client = AmazonS3ClientBuilder.standard().build();
}
