Coursier is a dependency resolver and artifact fetcher for Maven/Ivy repositories, written in pure Scala, serving as the Scala application and artifact manager. It provides a CLI (cs) to install Scala tooling and applications, plus an embeddable Scala library API for resolving and fetching dependencies.

Use cases

• install the Scala development environment with one command
• resolve and download Maven/Ivy dependencies fast and in parallel
• create standalone launchers for Scala applications
• install Scala CLI tools like scalafmt or sbt from the command line
• embed dependency resolution in my own Scala tool via an API
• fetch artifacts from Maven repositories in a Scala.js project
• replace Ivy-based dependency fetching in sbt builds

When to choose

• you work in the Scala/JVM ecosystem and need fast, parallel dependency resolution
• you want a one-command setup of the Scala toolchain including JVM, scala-cli, and sbt
• you need to programmatically resolve Maven/Ivy dependencies from Scala code
• you want to install and launch Scala applications from the command line

When to avoid

• your project is not JVM/Scala-based and uses npm, pip, or cargo for dependencies
• you need to publish artifacts rather than resolve and fetch them
• you require a stable binary API for the library, which is still subject to breakages
