nightly fails to start in some of my projects, latest works fine. Anyone else seeing this?

Working for me (linux-amd64)

I think the key word in my observation is “fails to start in some of my projects”. 😃 So for some of my projects it works and for others it doesn’t. I haven’t figured out a pattern.

Hum, interesting, it may be some change in master so

ericdallo 2025-05-19T13:54:24.334549Z

If you manage to repro in some public repo LMK

I see this trace in the lsp log:

it's indeed related to some changes I did

ericdallo 2025-05-19T14:04:50.189329Z

any public repro I can try?

ericdallo 2025-05-19T14:05:02.458439Z

glad you found this before a release hehe

I’ll see if I can find a public repo that repros it.

ericdallo 2025-05-19T14:09:29.639749Z

also if you could check clojure-lsp logs, there will have more info, maybe something before the exception

pez 2025-05-19T14:21:46.006229Z

This is probably not minimal. But it repros the problem:

(ns foo.bar)

#_#_#_#_1 2 3 4 5

(defn foo []
  (str #_#_#_#_"" '() "" '()))

#_{:clj-kondo/ignore [:clojure-lsp/unused-public-var]}
(def bar 1)

ericdallo 2025-05-19T14:22:05.788739Z

thanks, will take a look

ericdallo 2025-05-19T15:08:16.237829Z

@pez did a push fixing that case, a nightly should be available soon, LMK if any others please
