- Zinc 1 drops support for Scala 2.9 and earlier. Scala 2.10 must use 2.10.2 and above. Scala 2.11 must use 2.11.2 and above. (latest patch releases are recommended)
|
||||
- `config("tooling")` must be directly assigned to a *capitalized* `val`, like `val Tooling = config("tooling")`. This captures the lhs identifier into the configuration so we can use it from the shell later.
|
||||
- Changes `publishTo` and `otherResolvers` from SettingKeys to TaskKeys. [#2059][2059]/[#2662][2662] by [@dwijnand][@dwijnand]
|
||||
- `Path.relativizeFile(baseFile, file)` is renamed to `IO.relativizeFile(baseFile, file)`.
|
||||
- `PathFinder`'s `.***` method is renamed to `.allPaths` method.
|
||||
- `PathFinder.x_!(mapper)` is moved to `def pair` on `PathFinder`.
|
||||
- Drops sbt 0.12 style hyphen-separated key names (use `publishLocal` instead of `publish-local`).
|
||||
- Renames early command feature from `--<command>` to `early(<command>)`.
|
||||
- Log options `-error`, `-warn`, `-info`, `-debug` are added as shorthand for `"early(error)"` etc.

The Scala Center is working with Lightbend to provide [an automatic migration tool][sbt-migration-rewrites].
|

#### Zinc API changes
|

|

- Java classes under the `xsbti.compile` package such as `IncOptions` hides the constructor. Use the factory method `xsbti.compile.Foo.of(...)`.
|
||||
- Renames `ivyScala: IvyScala` key to `scalaModuleInfo: ScalaModuleInfo`.
|
||||
- `xsbti.Reporter#log(...)` takes `xsbti.Problem` as the parameter. Call `log(problem.position, problem.message, problem.severity)` to delegate to the older `log(...)`.
|
||||
- `xsbi.Maybe`, `xsbti.F0`, and `sxbti.F1` are changed to corresponding Java 8 classes `java.util.Optional`, `java.util.Supplier` and `java.util.Function`.

- Replace cross building support with sbt-doge. This allows builds with projects that have multiple different combinations of cross scala versions to be cross built correctly. The behaviour of ++ is changed so that it only updates the Scala version of projects that support that Scala version, but the Scala version can be post fixed with ! to force it to change for all projects. A -v argument has been added that prints verbose information about which projects are having their settings changed along with their cross scala versions. [#2613][2613] by [@jroper][@jroper]

|

This depends on some factors such as how your classes are organized, but you can see 3x ~ 40x improvements. The reason for the speedup is because it compiles fewer source files than before by untangling the classes from source files. In the example adding a method to scala/scala's Platform class, sbt 0.13's name hashing used to compile 72 sources, but the new Zinc compiles 6 sources.

### sbt server: JSON API for tooling integration
|
||||
|
||||
sbt 1.0 includes server feature, which allows IDEs and other tools to query the build for settings, and invoke commands via a JSON API. Similar to the way that the interactive shell in sbt 0.13 is implemented with `shell` command, "server" is also just `shell` command that listens to both human input and network input. As a user, there should be minimal impact because of the server.

|

sbt IO 1.0 add variant of `IO.copyFile` and `IO.copyDirectory` that accept `sbt.io.CopyOptions()`.
|

`CopyOptions()` is an example of pseudo case class similar to the builder pattern.

```scala
|

import sbt.io.{ IO, CopyOptions }
|

|

IO.copyDirectory(source, target)

// The above is same as the following

#### Library management API and parallel artifact download

||||
|

sbt 1.0 adds Library management API co-authored by Eugene Yokota ([@eed3si9n][@eed3si9n]) from Lightbend and Martin Duhem ([@Duhemm][@Duhemm]) from Scala Center.
|
||||
This API aims to abstract Apache Ivy as well as alternative dependency resolution engines Ivy, cached resolution, and Coursier.
|
||||
|
||||
Parallel artifact download for Ivy engine was contributed by Jorge ([@jvican][@jvican]) from Scala Center.
|
||||
It also introduces Gigahorse OkHttp as the Network API, and it uses Square OkHttp for artifact download as well.

#### Binary format for Zinc's internal storage
|
||||
|
||||
Jorge ([@jvican][@jvican]) from Scala Center contributed a binary format for Zinc's internal storage using Google Procol Buffer.
|
||||
The new format provides us with three main advantages:
|
||||
|
||||
1. Backwards and forwards binary compatibility at the analysis format level.
|
||||
2. Faster (1.5 ~ 2x) serialization/deserialization of the analysis file.
|
||||
3. Provides a better way to make the analysis file machine-independent.
