In my humble scenario, the plain installation instructions (and various Internet posts about how to get started) do not yield a working Clojure project in the intelliJIDEA + La Clojure.
I have imported a working leiningen project into the IDE. "Error running project: Clojure classes are not attached to module" is the error message received when attempting to run my simple Clojure project.
The REPL is running fine within the IDE, but can't run my project in the IDE.
Very frustrated at this. Posts like http://dev.clojure.org/display/doc/Getting+Started+with+La+Clojure+and+IntelliJ+IDEA?focusedCommentId=4653239#comment-4653239 seem to portray an over simplified if not wrong picture.
La Clojure not working out-of-the-box
