Question 1

How do I install Leiningen on Windows?

Accepted Answer

Use the batch file or PowerShell script from the stable branch, or run the shell script in the Linux subsystem. First, install Java, then download the script, place it in your PATH, and make it executable as per the installation guide.

Question 2

Leiningen vs Boot: which is better for Clojure?

Accepted Answer

Leiningen is more established and simpler for standard projects with strong automation and plugins, while Boot offers composable tasks for complex workflows. For most use cases, Leiningen's ease of use wins, but Boot is preferred for highly custom builds.

Question 3

How to add a dependency in Leiningen?

Accepted Answer

Edit the project.clj file and add the library coordinates under :dependencies, like '[org.clojure/clojure "1.8.0"]'. Then run 'lein deps' to fetch and manage dependencies automatically from repositories.

Question 4

What are Leiningen profiles and how do I use them?

Accepted Answer

Profiles allow custom build configurations for different environments. Define them in project.clj or ~/.lein/profiles.clj, and activate via commands or settings to override dependencies, plugins, or other options as detailed in the profiles guide.

Question 5

How to create a new Clojure project with Leiningen?

Accepted Answer

Run 'lein new app myproject' to generate a standard project structure. This uses templates to set up a project.clj file and directory layout, making it easy to start coding without manual configuration.

Question 6

Can Leiningen be used for Java projects?

Accepted Answer

While it can handle mixed Clojure/Java projects via plugins and guides, for pure Java projects, tools like Maven or Gradle are better suited due to their broader ecosystem and native support for Java builds.
