Summary of Changes

Hello @dhavalbhensdadiya-crest, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request significantly expands the Google Cloud Secret Manager Java samples by adding new functionalities for managing secrets with Customer Managed Encryption Keys (CMEK) and for manipulating secret annotations. These additions provide developers with clear examples for advanced secret management operations, ensuring better security and organizational control over sensitive data. The changes are accompanied by comprehensive documentation updates and robust integration tests to maintain code quality and reliability.

Highlights

• New Samples for Customer Managed Encryption Keys (CMEK): Introduced new code samples demonstrating how to create secrets with Customer Managed Encryption Keys (CMEK) in both global and regional scopes for Google Cloud Secret Manager.
• New Samples for Deleting Secret Annotations: Added new code samples for deleting annotations from existing secrets, covering both global and regional Secret Manager configurations.
• Documentation Updates: The README.md file has been updated to include instructions for enabling the Cloud KMS API, setting new environment variables for global and regional KMS keys, and granting the necessary Cloud KMS Encrypter / Decrypter IAM role.
• Integration Test Coverage: New integration tests have been added and existing test files modified to validate the functionality of creating secrets with CMEK and deleting secret annotations for both global and regional scenarios.

Code Review

This pull request adds new samples for creating secrets with Customer-Managed Encryption Keys (CMEK) and for deleting secret annotations, for both global and regional secrets. The changes include updates to the README, new sample files, and corresponding integration tests. My review focuses on improving the clarity and efficiency of the new sample code. I've pointed out some incorrect comments and region tags in CreateSecretWithCmek.java that seem to be from a copy-paste. I've also suggested a more efficient implementation for DeleteSecretAnnotations.java and its regional counterpart, which avoids an unnecessary API call.
