This folder contains executable examples of Mill builds, meant for learning purposes but also tested and verified for correctness.

The three sub-folders are:

1. basic/: the basic getting-started hello-world examples of using Mill

2. scalabuilds/: examples that walk you through getting from a minimal single-module Scala project to testing and publishing a multi-module multi-scala-version project

3. web/: this contains examples of doing basic web development with Mill as the build tool: going from a simple static HTML server to a client-server application sharing code between Scala-JVM and Scala.js, and publishing cross-platform Scala modules built across Scala-JVM and Scala.js

4. tasks/: examples demonstrating how Mill's various Task[T] flavors work, and in what kind of scenarios you would use each one

5. cross/: examples of Mill's cross-build capability, as a generic feature, beyond its specific usage in CrossScalaModule

6. misc/ examples that go deeper into the workings of the Mill build tool: dynamic cross modules, $file and $ivy imports, and using the mill-build/ folder.

7. thirdparty/: some example build.mill files for real-world Java and Scala codebases

Within each sub-folder, examples are numbered in the order they are intended to be read. Each example illustrates one key concept or technique, with the code followed by a comment explaining it, and an Example Usage block showing how the example can be used. By going through all of the examples, you should be able to learn everything that you need to be productive with the Mill build tool.
