Gradle can't find AWS libraries

I'm new to using the AWS SDK and SQS both. According to the docs, I added the following to my build.gradle.

// AWS  
implementation platform('com.amazonaws:aws-java-sdk-bom:1.11.X')  
implementation 'com.amazonaws:aws-java-sdk-sqs'  

But when I re-import in IntelliJ, I get the following errors:

Could not find com.amazonaws:aws-java-sdk-bom:1.11.X.
Required by:
project :

Possible solution:

• Declare repository providing the artifact, see the documentation at https://docs.gradle.org/current/userguide/declaring_repositories.html

Here's my dependencies section. I think MavenCentral should be enough.

repositories {
mavenCentral()
// for heavyweight software dependencies
flatDir {
dirs 'libs'
}
// Spock snapshots are available from the Sonatype OSS snapshot repository
maven { url "https://oss.sonatype.org/content/repositories/snapshots/" }
}

Please hit me up with any feedback.

Thanks.
