Coursier

2.0.4

Edit

Installation

Native launcher

Linux

On Linux, download and run the coursier launcher with

$ curl -fLo cs https://git.io/coursier-cli-linux &&
    chmod +x cs &&
    ./cs

macOS

Download and run the coursier launcher with

$ curl -fLo cs https://git.io/coursier-cli-macos &&
    chmod +x cs &&
    (xattr -d com.apple.quarantine cs || true) &&
    ./cs

Note the xattr command to circumvent notarization on macOS Catalina.

Alternatively, the native launcher can be installed via homebrew with

$ brew install coursier/formulas/coursier
$ cs

Windows

On Windows, use

> bitsadmin /transfer cs-cli https://git.io/coursier-cli-windows-exe "%cd%\cs.exe"
> .\cs --help

Note that this must be run with cmd.exe, not PowerShell.

JAR-based launcher

In case you run into any issue with the native launcher, a JAR-based launcher is available.

The commands below install the JAR-based launcher as coursier, which can be substituted to cs in the various examples on this website.

Linux / macOS

Download and run the launcher with

$ curl -fLo coursier https://git.io/coursier-cli &&
    chmod +x coursier &&
    ./coursier

Note that the JAR-based launcher requires Java 8 or later to run. That is, a command like java -version should print a version >= 8.

The JAR-based launcher weights only about 25 kB and can be easily embedded as is in other projects. It downloads the artifacts required to launch coursier on the first run.

Alternatively, on macOS, the JAR-based launcher can be installed via homebrew with

$ brew install coursier/formulas/coursier
$ coursier

Windows

Install and run the JAR-based coursier launcher from the current directory at the Windows prompt, with

> bitsadmin /transfer downloadCoursierCli https://git.io/coursier-cli "%cd%\coursier"
> bitsadmin /transfer downloadCoursierBat https://git.io/coursier-bat "%cd%\coursier.bat"

You can then run coursier from the same directory, like

> coursier resolve io.circe:circe-core_2.12:0.10.0

Arch Linux

Install it from AUR,

$ pacaur -S coursier

FreeBSD

Install it via pkg from the Ports Collection,

$ pkg install coursier

zsh completions

If you use ZSH, simple tab-completions are available by writing the coursier completion data into your completions directory. You can install the completions with:

mkdir -p ~/.zsh/completion
cs --completions zsh > ~/.zsh/completion/cs
echo 'fpath=(~/.zsh/completion $fpath)' >> ~/.zshrc
echo 'autoload -Uz compinit ; compinit' >> ~/.zshrc
