hello all. How do I rund depstar to only include .class and not .clj in jar?

Sounds like you want the :exclude regex option?

even when using uberjar

See https://github.com/seancorfield/depstar/#excluding-files

why is it including .clj in libs ?

not .class

Not all .clj files get compiled (Clojure itself has at least one .clj file that doesn't get compiled).

(just checked, Clojure 1.10.2 has 43 .clj files)

so, I can not provide a jar with only .class?

Even if you AOT your main namespace with depstar, anything that is not statically reachable from it will not be compiled: AOT is purely transitive. If you use :compile :all, it will attempt to compile all of your own namespaces -- not just your main ns -- but even that won't necessarily reach all possible .clj files in all the transitive dependencies.

yes, I used it :compile :all but I saw that other libs did not been compile

what is the matter about not compile everything into .class?

I just explained that.

shame me, sorry

what you normaly use? :compile :all ?

:compile :all will compile all the namespaces in your project, which will also transitively compile every namespace that is statically reachable from your code: that's how Clojure's compile function works. If there are namespaces in libraries you use that are not statically reachable from any of your namespaces, they will not be "seen" by compile and they will not be compiled to .class files. That means if you use :exclude to omit all .class files, you may fail at runtime if a namespace that was not statically reachable is then loaded dynamically. You should be able to :exclude just your own code's .clj files from the JAR if you're careful with the regex -- and you do not have any code that is only reachable dynamically.

At work, we just use :aot true :main-class <some ns>. We "don't care" if source ends up in the JAR and we "don't care" about the potential "runtime compilation" overhead for namespaces that are only loaded dynamically.

so, no way to exist an obfuscator to clojure?

Like I keep saying -- and as it explains in the section of the README that I linked to: you can use :exclude with a regex to omit .clj files -- but you need to be careful to not exclude something that ends up being dynamically loaded at runtime because those would not be compiled by Clojure (because they are not statically reachable).

And it's also worth pointing out that JVM bytecode decompilers exist: so even if your code is all .class files, folks can decompile that into Java source code for the most part. It's weird Java source code but it's going to allow anyone to figure out how your code works.

What problem are you trying to solve here?

I didn´t know that in .jar it´s carrying the .clj and someone can see it. The .class , I think, it´s more difficult to read it

I thought it was compiled all into .class stuffs

Nearly all Clojure libraries are source code. It's actually bad to compile a library since it can cause version conflicts later on. Compiling an uberjar/application is fine but all it does is improve startup time.

I got it. So, what happen when you compile to GraalVM?

No idea, never used it.

thanks for your explanation

As a concrete example:

Generating a project called example based on the 'app' template.
(! 686)-> cd example/
(! 687)-> cat deps.edn

            :exec-fn hf.depstar/uberjar

                        :main-class "fabrao.example"
