🚀 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.
