Stop Copying Gradle Code

If you've worked on a multi-module Android project, you know the pain: build.gradle.kts files multiplying like rabbits, each containing the exact same Android compileSdk , Kotlin compiler options, and Compose configurations. When you need to bump a version or change a compiler flag, you end up doing a massive "Find and Replace" across 20 different modules. We know we shouldn't copy and paste application code, yet we routinely accept copy-pasting our build configuration. It's time to stop. In this article, we'll explore how to use a build-logic module to create custom Gradle convention plugins. By moving boilerplate out of your module-level build files, you can enforce consistency across your entire project and make maintaining your build system a breeze. To demonstrate, we will reference a real-world implementation from the RandomPokemon repository. The "After" Picture: A Clean app/build.gradle.kts Before we look at how to build convention plugins, let's look at why we want them. Here
