🚀 Jakarta Migration (javax → jakarta)

Analyze, plan, and automate your Java EE → Jakarta EE migration — directly inside IntelliJ.

Migrate from Java EE 8 (javax.*) to Jakarta EE 9+ with confidence. This plugin detects migration blockers, analyzes dependencies, and helps you refactor safely using OpenRewrite.

⚠️ Free Trial Temporarily Unavailable

The free trial has been paused. We want to bring it back, but we need your help to make this project sustainable.

Sponsor this project on GitHub to help cover the time and effort of ongoing development. If this plugin has saved you hours of migration work, please consider giving back so we can continue building features and restore free trial access for the wider Java community.

Premium features (Advanced Refactor, platform detection, advanced scans, PDF reports, and AI-assisted migration) are available with a paid subscription. The free tier still includes migration risk analysis, dependency scans, version recommendations, and strategy insights.

Note: The free trial can still be accessed by installing v1.0 of this plugin.

⚠️ Why This Matters

The transition from javax.* to jakarta.* is not a simple rename.

• Dependencies break

• Frameworks require upgrades

• Application servers must change

• Hidden references cause runtime failures

This plugin helps you identify risks early and migrate systematically.

Anonymous Data Collection

This plugin collects anonymous usage statistics and error reports to help improve the product:

What we collect:

• Anonymous user ID (randomly generated UUID)

• Plugin version and environment

• Usage events (credit usage, upgrade clicks)

• Error reports with stack traces (when errors occur)

• Current UI tab and action context

What we DON'T collect:

• Personal information or identifying data

• Source code or project content

• IP addresses or location data

• User names or email addresses

How we use it:

• Improve migration detection accuracy

• Fix bugs and crashes faster

• Understand which features are most useful

• Plan future improvements

Data Storage:

• All data is stored securely in Supabase (GDPR compliant)

• Anonymous user IDs are stored locally in your IDE config

Opt-Out Options

You can disable data collection at any time:

Via About Tab:

1. Open File → Settings → Plugins → Jakarta Migration

2. Click the About tab

3. Toggle off "Usage Analytics" and/or "Error Reporting"

4. Changes are saved automatically

What happens when you opt-out:

• No new usage events will be collected

• No new error reports will be sent

• Previously collected anonymous data remains in Supabase

• Plugin functionality is not affected - all features work normally

🔍 What You Can Do

📊 Analyze Your Project

• Scan your entire codebase for javax.* usage

• Identify migration blockers and compatibility issues

• Estimate migration effort and risk

📦 Understand Dependencies

• Detect which dependencies are Jakarta-compatible

• Deep transitive scanning — find hidden javax.* references in your full dependency tree

• Get recommendations for compatible versions

• Visualize module relationships with dependency graphs

🧠 Plan Your Migration

• Compare migration strategies

• Identify required platform upgrades (Spring, app servers, etc.)

✅ Validate Migration Readiness

• Enhanced Test Coverage Analysis: Detects integration tests that actually validate javax/jakarta compatibility

• Critical Risk Zone Detection: Identifies modules with migration issues AND insufficient test coverage

• Migration-Aware Confidence Scoring: Prioritizes tests that catch real migration issues over mocked unit tests

📄 Generate Professional Reports

• HTML-to-PDF Reports: Beautiful, professional reports with executive summaries

• Multiple Templates: Professional, Technical, and Minimal report styles

• Comprehensive Analysis: Dependencies, platforms, advanced scanning, and recommendations

• Make informed decisions before changing code

⚡ Refactor with Confidence

• Apply OpenRewrite-powered refactoring recipes

• Automatically transform javax.* → jakarta.*

• Undo changes with built-in history

🧪 Advanced Refactor (Premium)

• Build complex multi-step refactor sequences

• Test refactors in isolated sandboxed testcontainers before applying

• Experiment history — compare results, re-run, and clone past experiments

• Safely validate that refactors won't break your build

🤖 AI-Powered Capabilities
