DevOps / Gradle8 Interview Questions

What is the purpose of settings.gradle?

settings.gradle is read first, during Gradle's initialization phase, and its main purpose is to tell Gradle which projects exist in the build — the root project's name and any subprojects to include.

rootProject.name = 'my-app'
include 'core', 'api', 'web'

// composite builds also declare included builds here
includeBuild '../shared-library'

Beyond declaring the project structure, it's also where plugin management and dependency resolution management can be centralized for the whole build — declaring which plugin repositories to search, or defining a shared version catalog available to every subproject. Because it runs before any project's build.gradle, settings.gradle is the one place configuration can affect the very shape of the build (which projects exist at all), not just how an existing project behaves.

What must settings.gradle declare for a multi-project build to work?
When is settings.gradle read relative to each project's build.gradle?
