To better understand what's going underneath, you're just calling the addURL method of the classloader. But since you might be evaluating this at the repl, there is an important point regarding the classloader. Everytime clojure evaluates a form, it will use a new classloader on that form, and the parent will be the classloader of the caller of the eval. So this means if you evaluate two forms consecutively, the first being the addURL, and the second, the command depending on the jar, the second will fail (unless you wrap both commands in a let). You need to ensure that the parent of the current classloader in the call to addURL is set. This way, all future evals will delegate to the classloader that knows about the jar.
So in summary, the heart of the command should just be: (.addURL (.getContextClassLoader (Thread/currentThread)) (.toURL (.toURI file))) For runtime dependency management, pomegranate does this, and so does my library, dj https://github.com/bmillare/dj -- You received this message because you are subscribed to the Google Groups "Clojure" group.
