Thank you! I was having a very difficult time trying to figure out how to get my compiled application to run, turned out I forgot to define :main in project.clj

You need to say:

java -jar helloworld-standalone.jar

not

java -jar helloworld.jar

I've written a simpler and briefer guide sharing my experience with using Leiningen for building Clojure programs, using the current version Leiningen 1.1.0. Not as detailed as yours here, and definitely based on what I learnt from yours, but thought I'd share what bits I know about the newer version.

Thanks for writing your guide here. Learnt a lot.

Hi Zef,
I am using leiningen 1.1.0 and 'lein uberjar' creates two jars, helloworld.jar and helloworld-standalone.jar . Only the latter works with 'java -jar helloword-standalone.jar'. You may want to check that your example is consistent with that. Thanks for your tutorial!

yes, actually it turns out the problem seems it is Mac OSX 10.4 that leiningen won't compile on, it works fine on the debian system I use, but thanks for a nice tutorial!

Hi,

I get exactly the same error as above when trying to compile with the same input files. Is something broken?

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.

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.
