Multi-Project Builds and Deployment

Configure and manage multi-project SBT builds for larger applications and prepare for deployment.

Why Multi-Project Builds?

As Scala applications grow, managing all code in a single project can become difficult. Multi-project builds help organize your codebase.

They allow you to:

  • Separate different modules (e.g., core logic, API, utilities).
  • Manage dependencies between these modules clearly.
  • Apply specific settings to individual parts of your application.

This approach improves modularity and maintainability.

Defining Multiple Projects

In SBT, you define multiple projects within your main build.sbt file. Each project is typically a lazy val.

The root project usually aggregates or depends on these sub-projects.

Here's a basic setup for a root project and two sub-projects:

lazy val root = project
  .in(file("."))
  .aggregate(core, api)

lazy val core = project
  .in(file("core"))

lazy val api = project
  .in(file("api"))
