## プロジェクトの歴史と使われ方

Coursier is a Scala application and artifact manager used to install Scala applications, set up Scala development environments, and download and cache JVM artifacts.

### プロジェクトの歴史

The public repository was created in 2015. The official overview describes Coursier as a Maven/Ivy-style dependency resolver and fetcher rewritten from scratch in Scala, designed to be fast and embeddable.

The README notes that large parts of Coursier development since September 2018 were funded by the Scala Center.

### 採用の歴史

Coursier became infrastructure in the Scala ecosystem rather than only an end-user CLI. The official users page lists Scastie, Scalafiddle, Ammonite, Mill, sbt, Pants, Scalafmt, Scalafix, Scala Jupyter kernels, and Scala language-server tooling as users or integrations.

The Coursier docs also record a major packaging milestone: sbt 1.3.x shipped with Coursier support enabled by default, reducing the need for the separate `sbt-coursier` plugin in most sbt 1.3.x builds.

### 使われ方

As the `cs` command-line tool, Coursier installs Scala applications, launches applications, creates standalone launchers, resolves dependencies, fetches artifacts, manages Java runtimes, and sets up common Scala tools.

For private repositories, credentials can be supplied inline, by environment or Java property, or via `credentials.properties` in platform-specific config locations.

### パッケージ好きにとっての重要性

Coursier matters to package and build-tool maintainers because it sits at the boundary between package managers, Maven/Ivy metadata, launcher generation, dependency caches, and Scala build reproducibility. It is both a CLI package and a library consumed by other tools.

### タイムライン

- 2015: Public GitHub repository created.
- 2018: Scala Center funding noted for large parts of development from September onward.
- 2019: sbt 1.3.x line documented as shipping with Coursier support enabled by default.
- 2026: v2.1.25 milestone releases continue.
