I was wondering whether putting a dot in a directory on the classpath makes a difference. On OS X, the answer is no. Unfortunately, I don't have a windows machine, so I can't check for certain what the situation is there.
Another issue: I ignored case-sensitivity in my answer above. Are windows paths ever case-sensitive? (silly question, I know, but I haven't worked with windows in a while.) Another question: If you run: java -cp "c:\clojure-contrib\clojure-contrib.jar;c:\clojure \clojure.jar;c:\projects.clj\examples" clojure.main can you then just do (require 'introduction) And do try it with quotes around the classpath. The dot in projects.clj might be like a space in that it could lead to a parsing error without quotes.
