🚀 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.

⚠️ 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.

� Privacy & Analytics

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
