Conferences and trade magazines are full of new programming languages, new tools, new hypes, which seemingly never cease to amaze. Quick results, direct feedback, and unprecedented productivity are suggested. The urge to incorporate the new into one’s software is awakened – until one is brought back to reality: their own legacy system.

Automatisierte Code-Wartung mit OpenRewrite

In Teil 1 dieser Serie habe ich gezeigt, wie OpenRewrite im Rahmen von Softwareentwicklungsprojekten zur Automatisierung von Code-Wartungsaufgaben verwendet werden kann. In diesem Beitrag zeige ich nun, wie man eigene OpenRewrite-Rezepte schreibt. Das hilft Dir nicht nur dabei, Refactoring-Aufgaben auszuführen, für die es keine öffentlich zugänglichen Rezepte gibt, sondern auch dabei, zu verstehen, wie OpenRewrite unter der Haube funktioniert.

Automated code maintenance with OpenRewrite

With the large number of software development projects in most organisations, keeping these projects up to date with the latest security patches and framework updates can be quite a task. OpenRewrite is a library that provides an automated solution to this problem. Using recipes written in Java, it can perform large-scale source code refactoring during the build process, preserving as much of the original code as possible. In this blog post, I will explain how OpenRewrite works and how you can use it to refactor your code base.

JDK 21, the next long-term support release

The newest JDK release, version 21, appeared on September 19th. A number of developers view it as a long-term support release that will be supported for at least the next five years. As many applications will presumably be updated to version 21 from JDK 17, the last long-term support release, we would like to take this opportunity to examine the relevant changes from 17 to 21.
