How to uberjar without bundling source code?

Question

The example given in https://clojure.org/guides/tools_build#_compiled_uberjar_application_build also copies all source files from the src folder into the uberjar. As I understand it, this is not strictly required for a compiled application? In my scenario where I don't want to distribute my source code along with the uberjar, can I simply not copy or exclude clojure source code? Or does that have subtle side effects? Why would I want source code in my uberjar to begin with?

Comments

I believe you need a bit more than just ommiting "src from the copy-dir call.
 That would work if you don't use any dependencies of your own but most applications are assembled from a collection of other modules/libraries.
In that case, you want to specify the `:exclude` key in the parameter map passed to `b/uber`. It's a sequence of things to exclude where each item can also be a regex.

NOTE: If you are building your uberjar on macOS, I also suggest excluding `LICENSE` because it tends to cause issues with the case-insensitive file system.

Answer 1

If you have compiled your Clojure source into classes, then you can just distribute the .class files in the uberjar. In that tools.build example, you can simply omit "src" from the copy-dir call (or omit the call entirely if you have no "resources" to copy).

For those using leiningen, :omit-source true will do the same trick [1].
