For me, last time I tried eglot, the problem was making it work with
dap-mode (which in turn iirc it's strictly coupled with lsp-mode). I
really need a debugger when developing and I don't feel quite at home
with GUD/RealGUD.

Actually I simply set (setq lsp-java-jdt-download-url
"https://download.eclipse.org/jdtls/snapshots/jdt-language-server-latest.tar.gz";)
and then I let lsp-mode download and build it. That's why I changed your
code

to
(format
  "find %s -name 'org.eclipse.equinox.launcher_*jar'"
  (expand-file-name
    ".cache/lsp/eclipse.jdt.ls/plugins"
    user-emacs-directory))

However, both with your code and with mine, now when I try to open a
java file I get this error:
Error in post-command-hook (#[0

Maybe this is part of the reason?
