Automated Code Refactoring with OpenRewrite

About this training
You have a huge code base and code wide refactorings take up a huge amount of time? Upgrading libraries and adjusting your code due to breaking changes is nearly impossible because almost all your code files are affected? Updating or adding license headers in your code files is a pain and everyone forgets it almost everytime? This sounds like a nightmare to me. Wouldn’t it be great to automate these annoying tasks? I have good news for you, and it is called OpenRewrite! In this session we will have a closer look at this tool and how it can help you with automated code refactorings. We will learn how to include it into your project and how the result of the applied refactorings look like with an example Java application.
