good article , i get leiningen working on windows but i had some issues,
first self-install dont works on windows: you have to download jars and set system vars.
Second i have tried to use last 1.2.o snapshot clojure.jar and didnt works (clojure-1.1.0.jar was the solution) and then "lein compile" raise a "project.clj not found". I had to change lein.bat to add "." to classpath.

It was interesting to read this article and I hope to read a new article about this subject in your site in the near time.

I wish it was this easy to work with on windows.

Actually, I would also expect it to clean the class files. Not sure why it doesn't.

Thanks Zef - sounds reasonable. I just sort of expected it to clean the class files etc that were used to compile my project.

Appreciate it, and of course the wicked fast response!

This is the intent, lein clean cleans all generated files and dependencies so that you end up with a clean source tree.

Perhaps someone can answer this because maybe I am not understanding it correctly. I randomly did a 'lein clean' today and it purged the clojure, contrib and swank jars in my /lib folder. Is this expected behavior or did I fail to configure my project? I did not handle the project.clj in anyway after the 'lein new' and 'lein deps'.

Thanks,
vss

Did you do lein jar, or lein uberjar? Because if you did lein jar, you still need all your dependencies to be on your classpath.

Fixed that. Thanks.

Same situation as feldt reports: fresh lein-stable install, same exception when trying to run helloworld.jar. On the other hand, running the helloworld-stanalone.jar works just fine.

Fresh install of leiningen stable, then changed project.clj to depend on 1.1.0-master-SNAPSHOT, everything compiles but when running helloworld.jar I get:

1.1.0-alpha is no more – it's 1.1.0-master

Done. Thanks for letting me know.

So recently we changed it so that self-install is only recommended for the stable branch. Zef: could you update the bin link at the top to the stable branch instead? http://github.com/technomancy/leiningen/raw/sta...

Thanks!

and you use the example program and buildfile as provided?

Hi
I just downloaded Leiningen (lein) as was attempting to initiate commands which results in the following errors:

I'm using (pretty sure) the latest lein. The uberjar is called -standalone.jar and the command for that also makes the .jar at the same time.

Thanks! I just downloaded and installed leiningen over the weekend. This is a good description of how to use it.

I think Phil (@technomancy) has done a fabulous job to help newbies like me work with Clojure easy.
