I’m really excited to have on stage Jonathan Leitschuh and Yahor Berdnikau, maintainers of ktlint-gradle. ktlint-gradle is a Gradle Plugin that allows you to lint and reformat your Kotlin code during a Gradle build. We’re going to touch and what are the challenges of building such a tool and a bit of the story of this project. Moreover, we’ll discuss on a topic which is really crucial in the OSS community: Sustainability. Most of us struggle to find new maintainers. It’s crucial to understand how we can foster a sustainable ecosystem and what are the risks of unmaintained projects.
