What is lein-tar

How far could you take a jar if the jar was in a tar? Possibly as
far as Myanmar. Or maybe Zanzibar, if you had a car.

Package your project up as a tarball!

Formerly known as lein-release.


With Leiningen 2

Add [lein-tar "3.3.0"] to your project's :plugins.

With Leiningen 1

Add [lein-tar "1.1.2"] to your project's :dev-dependencies.


$ lein tar

Creates myproject-1.0.0.tar including your project's jar, its dependencies, and everything in pkg/. A build.clj file may also be added, containing git and/or jenkins details about the build that generated your tar.

Advanced Usage

The out of the box behavior is customizable via options in project.clj and also via the command line.

Options in project.clj

lein-tar checks project.clj for a :tar entry, and looks there for a map like the following. Of course, the entire map and all its keys are optional, none of this is required.

:tar {:uberjar true
      :format :tar-gz
      :output-dir "foobar"
      :leading-path "bazquux"}
  • :uberjar allows you to specify whether you'd prefer to have your project's uberjar in the tar, rather than the project jar and dependency jars, the default is false
  • :format allows you to build a .tar.gz (:tar-gz) or .tgz (:tgz) file, if you wish, as opposed to just a .tar (the default)
  • :output-dir determines where the tar will be generated, by default it's the project's target directory (that is, the :target-path of the project)
  • :leading-path specifies the first path component of the files in the tar, by default it's "{project-name}-{project-version}", but you can override it here

Command line options

lein-tar also accepts option command line arguments.

  • --name/-n by default, the generated file name will be something like myproject-1.0.0.tar (or whatever extension :format uses). To change that, the -n or --name argument is supported. The following will create a tar file called custom-name.tar:

    $ lein tar --name custom-name

Known Issues

Due to absurd limitations in the Java file API, Unix permissions inside the tarball are an approximation[1]. Executable files will be given permissions of 0755, while other files will be 0644.
