Introduction

Change is the only constant and this is very true for code. Code changes because of changes in requirements, changes in third-part library dependencies, frequent security vulnerabilities etc. Few changes need significant refactoring across the code base. For example, consider migrating a Spring Boot application from 3.5 to 4.0. This is a major change with significant effort. This potentially may cause regression if not done properly. To make larger code refactoring easier, we need deterministic and reliable tool. For this, I came across OpenRewrite as an appropriate tool. It’s an open source automated code refactoring tool. It supports various refactorings like library updates, security vulnerability fixing, clean code updates etc.
