Note	New to Clojure? Head to the Getting Started guide instead for information on how to install the Clojure tools! These tools allow you to start a REPL for interactive use, download Clojure libraries (including Clojure itself), and run Clojure programs.

Stable Release: 1.12.5 (May 12, 2026)

Include the release in your project using the following coordinates:

deps.edn coordinate:

org.clojure/clojure {:mvn/version "1.12.5"}

Leiningen dependency:

[org.clojure/clojure "1.12.5"]

Dependencies

Clojure 1.12.5 depends on the following core libraries:

org.clojure/spec.alpha {:mvn/version "0.5.238"} (jar)
org.clojure/core.specs.alpha {:mvn/version "0.4.74"} (jar)

Using Clojure with a tool like the Clojure CLI or Leiningen will automatically include these libraries as transitive dependencies.

Java compatibility

Clojure depends on Java and all Clojure code is compiled to Java 8 compatible bytecode (newer versions of Java can load this as well).

Recommended: Java 25 (LTS releases are supported)
Minimum: Java 8

Clojure Source

Get Clojure

Via deps.edn

Specify the version of Clojure that you want in your deps.edn:

{:deps
 {org.clojure/clojure {:mvn/version "1.12.5"}}}

Via Leiningen

Modify the dependencies and repositories sections of your Leiningen project.clj file, specifying the version of Clojure that you want:

; under dependencies, select the release of clojure that you want
:dependencies [[org.clojure/clojure "1.12.5"]]

Using Clojure SNAPSHOT releases

Most tools do not automatically include the sonatype snapshot repositories. To use SNAPSHOT releases, you must add this to your configuration:

In deps.edn

Add an additional repository in deps.edn:

{:mvn/repos
 {"sonatype-oss-public" {:url "https://oss.sonatype.org/content/groups/public/"}}}

In Leiningen

Add a snapshot repository in Leiningen in project.clj:

:repositories {"sonatype-oss-public" "https://oss.sonatype.org/content/groups/public/"}

In Maven

In pom.xml:

<repositories>
  <repository>
    <id>sonatype-oss-public</id>
    <url>https://oss.sonatype.org/content/groups/public/</url>
    <releases>
      <enabled>true</enabled>
    </releases>
    <snapshots>
      <enabled>true</enabled>
    </snapshots>
  </repository>
</repositories>
