Which solution will meet these requirements?
Create an Amazon S3 bucket to store the dependency .jar file. Publish the dependency .jar file to the S3 bucket. Use an Amazon Simple Notification Service (Amazon SNS) notification to start a CodePipeline pipeline build.
Create an Amazon Elastic Container Registry (Amazon ECR) private repository. Publish the dependency .jar file to the repository. Use an ECR source action to start a CodePipeline pipeline build.

Create an AWS CodeArtifact repository. Publish the dependency .jar file to the repository. Use an Amazon EventBridge rule to start a CodePipeline pipeline build.
Explanations:
While using an S3 bucket to store the .jar file is a valid approach, simply publishing the file to S3 and using SNS does not automatically trigger a build in CodePipeline. You would need an EventBridge rule or S3 event notifications to invoke the pipeline.
Amazon ECR is primarily used for Docker images, not for .jar files. Although you could technically push a .jar file to ECR, it is not the intended use case, and there is no automatic trigger for CodePipeline builds based on new versions of the .jar file in ECR.
Similar to option B, ECR is not designed for .jar files. Although it is possible to publish the file there, it does not facilitate automatic triggering of a CodePipeline build without additional configurations like webhooks or notifications.
AWS CodeArtifact is designed for managing software dependencies, including .jar files. By publishing the .jar file to a CodeArtifact repository and setting up an EventBridge rule to monitor for changes, the pipeline can be automatically triggered to build whenever a new version of the .jar file is available, meeting the requirement.
I evaluate that the answer is:
Create an AWS CodeArtifact repository. Publish the dependency .jar file to the repository. Use an Amazon EventBridge rule to start a CodePipeline pipeline build.
