For many Kotlin developers, Gradle is a mysterious black box - a tool that somehow builds their app. On good days, it just works. On bad days, it becomes a source of endless frustration: trial-and-error, copy-pasting from Stack Overflow, and, more recently, help from our AI overlords. But what if it didn’t have to be this way? What if just a bit of foundational knowledge could make Gradle feel far less intimidating - and maybe even empowering? That’s the goal of this talk. This talk aims to demystify Gradle by giving you a practical understanding of its core concepts. We’ll cover: - What Gradle actually does during a build - How tasks, plugins, source sets, and dependencies fit together - How to debug Gradle scripts and plugins - Lazy configuration and the configuration cache (and how not to break them) You’ll also get concrete tips on how to keep learning Gradle without getting overwhelmed. This talk is for Kotlin developers who want to stop treating their build tool as a necessary evil and start using it with confidence.
