Online Meeting - Automated Mass Refactoring for Java-Based Applications

Abstract
This talk will focus on how engineering teams can leverage automated refactoring tools that originated at Netflix to greatly reduce the time and effort required when migrating to new versions of frameworks like Spring and JUnit and between language versions. Does this scenario sound familiar?

Your organization has many applications that are critical for the day-to-day operation of your business. Over time, you find that your applications have many dependencies on third-party technologies and libraries that have different release cadences. Invariably, your organization encounters pressures to upgrade those dependencies for any number of the following reasons: critical bug fixes, security updates, expiring support, "modernization," or technical enablement. Refactoring a single application to update its third-party dependencies can be tricky and often requires manual intervention when there are breaking changes. Performing the same refactoring operation across all of your applications can result in weeks or months of effort at the organization level.

This talk introduces OpenRewrite, an open source ecosystem specializing in mass, automated refactoring focusing on Java source code, Maven build files, XML, YAML, and property files. We will discuss how the framework enables the creation of composable, prepackaged recipes that can be used to automate common framework migration and how these recipes can be integrated into both Maven and Gradle builds.
This talk will include some live demonstrations of Rewrite's tools to perform automated migrations on real-world, Spring applications and libraries.
