LEININGEN(1)

NAME
lein - Automate Clojure projects

SYNOPSIS

lein [-o] [-U] [TASK [ARGS]]
lein [-h|--help]
lein [-v|--version]

DESCRIPTION

Leiningen is for automating Clojure projects without setting your hair on fire.

Working on Clojure projects with tools designed for Java can be an exercise in frustration. With Leiningen, you just write Clojure.

TASKS

lein help will show the complete list of tasks, while lein help TASK shows usage for a specific one.

lein help tutorial has a detailed walk-through of the various tasks, but the most commonly-used are:

    lein install
        install a project into your local repository

    lein deploy [REPOSITORY]

    lein show-profiles

    lein trampoline [TASK]

-h, --help
    Print this help or help for a specific task.

-v, --version
    Print Leiningen's version.

CONFIGURATION

Leiningen reads its configuration from the project.clj file in your project root. Either use lein new to create a fresh project from which to work, or see the exhaustive list of configuration options with lein help sample.

You can customize your project map further with profiles; see lein help profiles.

BUGS

Check https://codeberg.org/leiningen/leiningen/issues to see if your problem is a known issue. If not, please open a new issue on that site. Please include the output of lein version as well as your project.clj file and as much of the relevant code from your project as possible.
