GitHub Copilot modernization – Java Upgrade CLI Plugin
GitHub Copilot modernization – Java Upgrade CLI Plugin helps you upgrade your Java applications directly from the command line. It brings the same intelligent modernization capabilities as the VS Code extension to your terminal and CI/CD pipelines, enabling you to:
- Analyze your project, assess your dependencies, and generate an upgrade plan
- Execute the plan to automatically transform your codebase
- Fix build issues and resolve migration errors during the upgrade process
- Validate your application against known CVEs after the upgrade
- Output a detailed summary including file changes, updated dependencies, and upgrade results
Installation
copilot plugin install modernize-java@awesome-copilot
Quick Start
copilot --model claude-sonnet-4.6 --agent modernize-java:modernize-java
Key Capabilities
🔍 Intelligent Analysis and Upgrade Planning
Modernization starts with understanding your code. The CLI automatically analyzes your Java project and generates a customizable upgrade plan that you can review and edit before execution.
🔧 Automatic Code Transformation and Error Fixing
The CLI applies code transformations, automatically resolves build issues, and runs test validations — ensuring a smooth, error-free upgrade process without manual intervention.
🛡️ Post-Upgrade CVE Validation
After upgrade, the CLI scans for CVE (Common Vulnerabilities and Exposures) issues and code inconsistencies, then reports detected issues with suggested fixes to improve your application's security posture.
🔄 Upgrade Summary
At the end of each upgrade run, the CLI outputs a structured summary covering file changes, updated dependencies, test validation results, and any remaining issues — suitable for review in pull requests or CI logs.
