Full Changelog: 0.11.0...0.11.1

0.11.0

Mill 0.11.0 is a breaking release with a focus on polish. This release fixes many long-standing sharp edges that could not be fixed without breaking backwards compatibility, and cleans up the Mill codebase for better maintainability and so we can offer better compatibility guarantees going forward. User-facing improvements include an overhauled documentation-site, much easier cross builds, faster/more-robust bootstrapping, better error messages. It aims to do everything Mill already does, but better.

One thing especially worth calling out is that the Mill documentation has been overhauled, with new sections Scala Build Examples, Scala Module Configuration, Web Build Examples, and many more. These examples all live in the example/ folder, and zips containing them can be downloaded from Github Releases to easily try them out or bootstrap a new project. This should make it much easier to learn Mill: what features exist, why they are necessary, and how you can use them in a realistic setting to configure a Mill build for a variety of real-world scenarios. All examples are executable, and are executed as part of Mill's CI to ensure they are correct and up to date. The Mill Scaladoc is now also aggregated and published with each release

Major changes that may require migration:

• The mill._ import now has to be included explicitly at the top of your build.sc, and is no longer added implicitly

• Mill no longer runs the build.sc file using Ammonite, and instead bootstraps build.sc itself using Mill.

  • Any build.sc compilation "pre-def" customization that may have been done using Ammonite's import $file.foo or import $exec.foo now has to be done using Mill meta-builds.
  • Normal import $file and import $ivys should continue working

• The ./mill bootstrap script now downloads Mill from Maven Central rather than Github Releases.

  • This should help improve the robustness of Mill bootstrapping, such that Github outages would no longer cause Mill bootstrapping to fail (Maven Central outages cause bootstrapping failure regardless).
  • We will continue publishing the Mill artifacts to Github Releases for compatibility, but please update your ./mill script to the latest version (from this release) via curl -L https://github.com/com-lihaoyi/mill/releases/download/0.11.0/0.11.0 -o mill to benefit from this

• Cross build syntax has been overhauled:

  • Rather than using class Foo(crossValue: T) extends Module, they are now defined by trait Foo extends Cross.Module[T].
  • Cross modules no longer add their cross-keys to the millSourcePath by default. If you previously had a def millSourcePath = super.millSourcePath / os.up, you must remove it. If you previously did not have that, you must add def millSourcePath = super.millSourcePath / crossValue
  • See the Cross-Scala Version Modules or Cross Build Documentation for more details of how things work now.
  • PlatformScalaModule has been introduced to simplify cross JVM/JS/Native modules: automatically inferring the jvm/js/native platformSuffix from the module path, automatically adding -${versionSuffix} source folders, and automatically removing the platformSuffix from the publish artifact path.
  • Test modules now automatically follow the source-folder layout of their parent module (#2531), removing much of the need for manually override def sources in your test modules to set up cross version/platform sources
  • See the Publishing Cross-Platform Scala Module or Publishing Cross-Platform Scala Module Alternative documentation to see how you can use these

• Target resolution now instantiates modules substantially more lazily, often not instantiating them at all unless strictly necessary.

  • This may help improve startup performance for working with large build files
  • This means that for modules who override def millModuleDirectChildren, you need to additionally inherit from the marker trait DynamicModule so Mill knows to instantiate the module and use your override during resolution

• The mill.modules package has been removed, with functionality moved to mill.util and mill.scalalib

• The Tests trait has been removed, as it relies on trait shadowing that will be removed in Scala 3. Please use ScalaTests/ScalaJSTests/ScalaNativeTests instead

• The ScalaModule#run command now takes a args: Task[Args] instead of args: String*, allowing it to be easily used in the implementation of tasks. example

• RunScript.resolveTasks has been replaced by mill.resolve.Resolve.{Segments,Tasks}

Example Build Migrations

Below is a link the to 0.10.x -> 0.11.0 build migrations for a number of the com.lihaoyi projects, in order from simplest to the more complex. These may be useful to skim through to see what kind of changes a "typical" Mill project would need to do migrating to 0.11.0

• MainArgs
• Fansi
• OS-Lib
• PPrint
• Scalatags
• Cask
• uPickle
