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 Amazon Elastic Container Registry (Amazon ECR) private repository. Publish the dependency .jar file to the repository. Use an Amazon Simple Notification Service (Amazon SNS) notification to start a CodePipeline pipeline build.
Create an AWS CodeArtifact repository. Publish the dependency .jar file to the repository. Use an Amazon EventBridge (Amazon CloudWatch Events) rule to start a CodePipeline pipeline build.
Explanations:
Using S3 and SNS does not automatically trigger a build in CodePipeline when the .jar file is updated in the bucket. SNS would need to be manually set up for this, and it is not directly integrated with CodePipeline for this use case.
ECR is meant for storing Docker images, not .jar files. It is not the best fit for storing application dependencies like a .jar file, and it doesn’t directly integrate with CodePipeline for this purpose.
Although ECR can store .jar files, it is primarily for container images. Also, SNS would not directly trigger a CodePipeline build in this scenario, as the integration would not be seamless.
AWS CodeArtifact is a repository designed for managing dependencies like .jar files. You can publish the dependency to CodeArtifact, and then use an EventBridge rule to trigger a CodePipeline build when a new version is available.
I would say the answer is:
Create an AWS CodeArtifact repository. Publish the dependency .jar file to the repository. Use an Amazon EventBridge (Amazon CloudWatch Events) rule to start a CodePipeline pipeline build.
