Key Capabitlies

🔍 Intelligent Analysis and Upgrade Planning

Modernization starts with understanding your code. The extension automatically analyzes your Java code and generates a customizable upgrade plan that you can review and edit within VS Code.

🔧 Automatic Code Transformation and Error Fixing

Modernization isn’t complete until your application builds successfully. GitHub Copilot app modernization - upgrade for Java executes tools like open-source tools like OpenRewrite to apply code transformations, automatically resolve build issues, and run test validations — ensuring a smooth, error-free upgrade process.

🛡️ Post-Upgrade CVE Validation

After the upgrade process is completed, the tool scans for CVE (Common Vulnerabilities and Exposures) issues and code inconsistencies. When such issues are detected, it automatically applies fixes within VS Code Agent Mode, allowing the user to review the changes. This enhances the application's security posture and ensures compliance with organizational guidelines.

🔄 Summarizing the Upgrade Process

The summary at the end of upgrade provides you with an overview of key details, including file changes, updated dependencies, test validation results and remaining minor issues.

🧪 Unit Test Generation

In addition to Java upgrade, GitHub Copilot app modernization - upgrade for Java can also help generate unit test cases separately to boost the unit test coverage.
