Configure download agent

[wangmiao1002]

My machine has restricted the external network access environment. When using shadow cljs, the jar cannot be downloaded. How can I set up proxy downloading? Thank you

You can use :maven {:mirrors ...} in shadow-cljs.edn or ~/.shadow-cljs/config.edn. The :maven map takes the same options as leiningen would in its place. So :proxy is supported as well. Don't really know what that looks like though since I have never used it.

If you have a working setup for deps.edn or lein you can just use those tools instead to download the dependencies.

[wangmiao1002]

OK, let me try. Thank you for your answer

I have the same problem and couldn't get the :maven-configuration to work.
Since I also could never get this working with Leiningen, I wrote a small bb-task that would download all (transitive) dependencies and bundle them in a zip (which I can get behind the firewall).

I just published it: https://github.com/MrGung/deps-bundler

[MrGung]

I just realised that my solution currently does not bundle POMs. Also, shadow-cljs-2.19.3-aot.jar ist not included.
I'll fix that when time permits.

[thheller]

What is the particular issue blocking you from accessing maven directly? And what is the particular problem with maven configuration? Do you have access to a mirror or a proxy?

Instead of zipping the dependencies you could just rsync (or similar) the ~/.m2/repository folder after downloads are finished. That'll include all the necessary files. Just downloading the classpath .jars is not enough to actually build a classpath.

The AOT variant you can download via thheller/shadow-cljs$aot in deps.edn instead of just thheller/shadow-cljs.

[MrGung]

My company totally blocks access to the internet. rsync is therefore not possible. Maven is accessed via a proxy. There is no proxy for clojars.

I haven't investigated the issue with the configuration further - because even if I could access maven then, I'd still miss dependencies from clojars.

This morning I downloaded 3 or 4 missing POMs and the AOT-variant manually. shadow-cljs works for now.
