I can't get eglot to open the source for functions in Clojure jars, but decompiling Java works fine

[stig]

I'd love to be able to "drill down" into Clojure code that my project depends on, but it's not working for me. However, I can see the source for (decompiled) Java programs. I made this 35-second video to show the issue. In it I'm running M-. (xref-find-definititon) on first the println symbol (fails), then the IllegalStateException symbol (success) and finally the str/blank? symbol (fails):

eglot-bug.mov

The project was created by running lein new eglot-bug-repro and editing the src/eglot_bug_repro/core.clj file slightly to add the str/empty? and Java exception, just to have a couple more examples (including the successful one) than the generated project has.

I'm on MacOS, and I'm installing emacs, eglot, and clojure-lsp with Nix. (My flake is here.)

Versions:

• Eglot Version: 1.15
• GNU Emacs 28.2 (build 1, aarch64-apple-darwin22.4.0, NS appkit-2299.50 Version 13.3 (Build 22E252))
• clojure-lsp:

  $ clojure-lsp --version 
  clojure-lsp 2023.05.04-19.38.01
  clj-kondo 2023.04.15-SNAPSHOT

Answering myself, I asked this question in the clojurans #emacs channel and was pointed to https://git.sr.ht/~dannyfreeman/jarchive which fixes this problem for me.
