Install Clojure on Windows

Choose between WSL and the Windows Clojure installer, verify Java first, and set up a Windows workflow that matches the Clojure tutorials and tools you plan to use.

Windows is a valid Clojure development environment, but you should choose the workflow deliberately. The official Clojure install guide recommends Windows Subsystem for Linux (WSL) when you want the closest match to most Clojure tutorials and command-line documentation. The Windows installer is also available when you want a native Windows command.

Choose A Windows Path

Option Best fit Trade-off
WSL You want Linux-like shell behavior, tutorial compatibility, and familiar Unix tooling You must understand the Windows/WSL filesystem boundary
Windows installer You want native Windows commands and minimal shell change Some tutorials assume Unix commands or clj behavior
Existing Java IDE terminal You already work inside IntelliJ, VS Code, or another tool Make sure the integrated terminal uses the same Java and Clojure commands

For most Java engineers learning Clojure from community examples, WSL is the least surprising path.

Verify Java First

Before installing Clojure, verify Java from the same environment where you will run Clojure.

In Windows Command Prompt:

1java -version
2javac -version

In PowerShell:

1java -version
2javac -version

In WSL:

1java -version
2javac -version

Do not assume that Java installed on Windows is automatically available in WSL. Treat WSL as a separate Linux environment unless your team has documented a different setup.

Install With WSL

If you use WSL:

  1. Install or open a Linux distribution in WSL.
  2. Install Java inside that distribution.
  3. Follow the Linux Clojure CLI instructions from the official install guide.
  4. Verify the commands inside WSL, not only in Windows.
1clj -h
2clojure --version

Keep your project files in a location that your editor and WSL workflow both handle well. Avoid creating a performance or path-confusion problem by constantly crossing the Windows/WSL filesystem boundary without understanding it.

Install Natively On Windows

If you install natively, use the Windows installer referenced by the official Clojure install guide. After installation, open a new terminal and verify:

1clojure --version
2clojure -Spath

Native Windows setup is useful when the rest of your toolchain is already Windows-native. Just be careful when copying commands from Linux-oriented tutorials.

Team Checklist

Check Why it matters
Decide WSL or native Windows Avoids mixing paths, shells, and installed tools accidentally
Verify Java in the chosen environment Clojure starts on that JVM, not a different one
Verify clojure --version Confirms CLI command availability
Start a REPL from the editor Confirms the editor uses the same project environment
Document the chosen path Prevents every Windows developer from inventing a different workflow

Knowledge Check

### Why does the official guidance recommend WSL for many Windows learners? - [x] It closely matches the Linux-style commands used by many Clojure tutorials and docs. - [ ] Clojure cannot run natively on Windows. - [ ] Java is unavailable on Windows. - [ ] Leiningen only works in WSL. > **Explanation:** Native Windows works, but WSL reduces command and shell mismatches for many learning resources. ### What should you verify before installing Clojure in WSL? - [x] Java is installed inside the WSL environment. - [ ] Windows Explorer can open every source file. - [ ] A global `CLASSPATH` is set. - [ ] The project has no tests. > **Explanation:** WSL has its own environment. Verify Java where Clojure will actually run. ### What is the main risk of mixing native Windows and WSL setup casually? - [x] Different paths, shells, Java installs, and command availability can make failures hard to diagnose. - [ ] Clojure source files become unreadable. - [ ] The JVM stops supporting bytecode. - [ ] Markdown tables stop rendering. > **Explanation:** The tools may all be installed, but not in the same environment. Consistency matters more than the platform choice.
