Can tools.deps.alpha take into account the "localRepository" directive from maven settings.xml?

Question

tools.deps.alpha does not take into account the "localRepository" directive from maven settings.xml.
According to the code (https://github.com/clojure/tools.deps.alpha/blob/dae323631f67cfdf1e4769c7a193f7b6373f448d/src/main/clojure/clojure/tools/deps/alpha/util/maven.clj) the local repository seems to
be hardcoded to $HOME/.m2/repository.
Is there an option to override that behavior?

Answer 1

You can set :mvn/local-repo at the root of your deps.edn to change the local repository location. This can be combined with -Sdeps to set it dynamically on the command line if needed:

clj -Sdeps '{:mvn/local-repo "/foo"}'

Thank you for your answer.
Note that it seems that I cannot make it work on Windows but I think it is linked to the specifics of that OS. I will test on wsl to confirm (or not) that.
clj -Sdeps '{:mvn/local-repo "D:/temp/m2repository"}'

I suspect this is a shell quoting difference - you could try putting it in your deps.edn and see if that works to check.

---

Also see https://github.com/clojure/tools.deps.alpha/wiki/clj-on-Windows#escaping-quotes

Yeah, on Windows, you would use:

clj -Sdeps '{:mvn/local-repo ""D:\\temp\\m2repository""}'

---

I confirm that it works in the deps.edn and from the command line when escaping correctly the quotes:

Powershell: clj -Sdeps '{:mvn/local-repo ""D:/temp/m2repository""}'

Do you think it is worth raising an issue to have tools.deps read the localRepository directive in the maven user configuration (settings.xml)?

I'm not planning to add that, so no
