Does elin require java?

[knalasol]

When I try to run ./bin/elin --help or the bb command to debug suggested at #42, I get an error of
Exception in thread "main" java.lang.Exception: Couldn't find 'java'. Please set JAVA_HOME.
which leaves me to wonder: does elin require java? The repo page says that I only need Neovim and Babashka.

When I open a bb file, I get a Failed connecting to Elin server: port=#####, error= error.
I also seem to fail to connect silently if I call :ElinInstantConnect babashka or :ElinConnect [n] where n is the port provided by bb nrepl-server.

To Reproduce
Install elin with vim.pack on neovim nightly, having babashka installed but not clojure nor java, and run elin --help

Expected behavior
no error, elin connecting to repl server

Environemnt:
Arch Linux
Neovim v0.12.0-dev-### (nightly)
Babashka v1.12.215

Configuration file (if you have):
N/A

Project local configuration:
N/A
(I am trying to use elin within a standalone babashka executable as described in documentation section 2.3)

I can confirm that installing a headless JRE resolves the issue and allows elin to work as expected. I used OpenJDK 25.

The explanation seems to be this line from the Babashka book:

The :deps entry is managed by deps.clj and requires a java installation to resolve and download dependencies.

Since java is not otherwise required to use the babashka binary, it is not listed as one of its installation requirements (and I've gotten by without it so far). However, elin demands it, at least by making use of the :deps entry in its bb.edn.

(P.S. Thanks for making this project!)
