🗓️ Thursday, December 4 | 11:00 AM - 3:00 PM ET

Join a live, hands-on session to learn how to run and author OpenRewrite recipes — from declarative YAML to advanced imperative transformations. Whether you’re upgrading Java, migrating Spring Boot, or refactoring your own libraries, you’ll learn the methods to automate changes quickly, safely, and at scale.

‍Why Attend

‍By the end of this workshop, you’ll be able to:

• Run OpenRewrite recipes across thousands of files or repos to handle real-world scenarios like upgrading frameworks, removing deprecated APIs, and enforcing team-specific standards.
• Author declarative (YAML), Refaster-style, and imperative recipes for your own migrations.
• Use Preconditions to control recipe execution and ensure safety.
• Unit Test Recipes to verify accuracy before applying changes.
