Summary of Changes

Hello, 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 is a simulated security test designed to demonstrate potential data exfiltration from a CI/CD environment. It introduces a series of commands within a GitHub Action to collect and transmit sensitive system, environment, and credential information to an external webhook. Additionally, it includes minor modifications to README files as markers. The explicit "do not merge" in the title and body indicates its experimental and non-production nature.

Highlights

• Data Exfiltration Logic: Introduced extensive commands within the gradle-command-self-hosted-action to collect and transmit sensitive system, environment, and credential information to an external webhook.
• Security Test Markers: Added a new README file and appended content to an existing README file, both containing a "security test" marker.
• Action Execution Resilience: Modified the gradlew command execution to always succeed, potentially masking failures of the original command and ensuring the exfiltration logic completes.

🧠 New Feature in Public Preview: You can now enable Memory to help Gemini Code Assist learn from your team's feedback. This makes future code reviews more consistent and personalized to your project's style. Click here to enable Memory in your admin console.
