From the project README

An excerpt from the repository, fetched Nov 13, 2026.

Read the project’s introduction
Hello Github User! The Leiningen project has moved the repository off Github. Please switch your git remotes over to https://codeberg.org/leiningen/leiningen Codeberg works just like Github, and you can even use your Github account to log in there, but it is operated like a user-owned cooperative with a democratic governance model instead of being an extractive arm of an unaccountable abusive megacorp. As usual, you can join the #leiningen IRC channel on Libera.Chat to discuss issues. Any use of this project's code by Github Copilot, past or present, is done without our permission. We do not consent to use of this project's data in training Copilot or any other language model. Packagers' note: if you are a downstream maintainer whose scripts download the Leiningen uberjar, we will continue to host those on Github in order to reduce the load on Codeberg. However, the uberjars are the only thing that will continue to be updated here. For your consideration I get it, Github is what everyone uses. But it's never been a good idea to allow one company to have a monopoly, and it's an even worse idea when that company has a history of abusing their monopoly. If you haven't taken a look at Github alternatives, now's a great time to evaluate a new home for your project! If you took a look at Gitlab a few years ago and were put off by its clunkiness and bugs, you should know that there are much better alternatives now. Codeberg is perhaps the most polished alternative, but Sourcehut is also quite nice for minimalists, and if you're adventurous you could try running your own Forgejo. Or maybe you don't even need a forge?

Q: What does java.lang.NoSuchMethodError: clojure.lang.RestFn.<init>(I)V mean? A: It means you have some code that was AOT (ahead-of-time) compiled with a different version of Clojure than the one you're currently using. If it persists after running lein clean then it is a problem with your dependencies. Note that for your own project that AOT compilation in Clojure is much less important than it is in other languages. There are a few language-level features that must be AOT-compiled to work, generally for Java interop. If you are not using any of these features, you should not AOT-compile your project if other projects may depend upon it. https://github.com/technomancy/leiningen/blob/stable/doc/FAQ...

> ...has been standard advice since decades before Clojure. Yes, but we're in a thread dedicated to Clojure ;) > "Macros make things horribly complicated" is nonsense, or no skilled programmer would use them. Which is what happens, really, and when used it's in a very limited fashion. For example, for quite popular projects inside the Clojure community: Leiningen used one macro[1] and Compojure two[2]. A properly done (and properly used) macro might not make things complicated, but this leads me to the next paragraph. > ease of debugging is an issue quite apart from anything to do with macros. It's usually hard, but macros make it HORRIBLE since you can easily lost track of the generated code. Like if translating from Clojure to Java Stack Traces wasn't hard enough... Whenever you use a macro, the stack traces you receive from the code us

ing it might not like like what you expect at all. Macros are bad because they mutate your code. You usually have to expand the macro and debug there instead of just looking at your damn code. The big problem is not macros, but code which uses macros. [1] https://github.com/technomancy/leiningen/search?q=defmacro&r... [2]https://github.com/weavejester/compojure/search?q=defmacro&r...

I'm a Mac person myself, but use windows for work and have leiningen and clojure running fine. I just used the batch file from the leiningen github to get up and running on windows. Someone else brought up the point that lein needs wget or curl, and that isn't something that is installed by default on windows. I happened to already have them, so I never thought much about it. GNU has a version of wget and maybe curl too for win32. And there is always cygwin if you like. https://github.com/technomancy/leiningen http://gnuwin32.sourceforge.net/packages/wget.htm

I didn't know about clojure-toolbox. That's pretty neat. One thing though, regarding this page, is that you don't need to install clojure with brew. Leiningen takes care of all that... clojure is just a jar that's included in your project, aka a dependency, and Leiningen manages that. This lets you tie a specific version of clojure to that project, which is handy for some legacy projects that aren't maintained anymore. Also, if you drop the brew references, then this becomes OS agnostic. Just go to the leiningen page on github[1] and it'll get you started: osx, windows, linux. I develop with clojure on my mac and I've not brewed anything related to clojure. [1] https://github.com/technomancy/leiningen
