I can’t reproduce this. Is there something else in your file that might make this happen?

Apparently because the exmaple I gave you works fine here 😕

sec

Now I can't find it or repro

Too bad. Would be great with something minimal like what you posted, but with whatever it takes to repro. Next time! 😃

I'll be looking for it and next time I'll make sure it's reproducable

I've had this happen before, but only when using CTRL+ALT+L in VSCode. It only happens if you comment code using #_ { "key": "ctrl+alt+l", "command": "calva-fmt.alignCurrentForm", "when": "calva:keybindingsEnabled && editorTextFocus && !editorReadOnly && !hasOtherSuggestions && !suggestWidgetVisible && editorLangId == 'clojure'" } Heres the devtools error:

Error:

; Execution error (NoSuchMethodError) at clj-yaml.core/make-yaml (core.clj:126).
; org.yaml.snakeyaml.representer.Representer: method <init>()V not found

(defn ^:private load-yaml [fileName]
  (-> fileName
      (io/resource)
      (slurp)
      (yaml/parse-string)))

The (yaml/parse-string) generates the error I’m using latest clj-commons/clj-yaml {:mvn/version "1.0.27"}, Version 1.0.26 works fine. Runtime code works fine. Its just in my VSCode that I see the error

Commands that I run in Calva: ctrl + alt + c, ctrl + alt + j (this starts the repl) ctrl + alt + c, then click enter, to evaluate file.

:require [ :as io]
            [clj-yaml.core :as yaml]

Let me know if there is anything you need to reproduce.

What is meant with “Runtime code works fine”?

Our clojure main, runs in our kubernetes DEV environment without issues.

Does it load this file?

Yes. I believe so. Just switching versions to 1.0.26 works.

Here is a partial stacktrace:

clj-yaml.core/make-yaml (core.clj:126)
clj-yaml.core/make-yaml (core.clj:102)
clojure.core/apply (core.clj:667)
clojure.core/apply (core.clj:662)
clj-yaml.core/parse-string (core.clj:301)
clj-yaml.core/parse-string (core.clj:263)
viasat.sdp.api.smoketests.config/load-yaml (config.clj:13)

Can you load the file from the command line repl?

I’m not setup to do that locally, I can try it tomorrow. But because the runtime works, I feel like it should probably work too.

How can Calva evaluate the file if you can’t do it from the command line? (I’m not very familiar with kubernetes.)

Pez, if you can give me the steps, I’ll do it. I went straight to Calva in working with Clojure. And I’m working with existing functionality.

Anyways, I was just letting you know in case you want to look at it. I can use the old version for now.

Is it a Leiningen project?

no its a deps.edn.

Don’t worry about it man. We can look into it next time

I thought it would be super easy for you to try it out, but looks like it might be kind of tough

Haha, I am already worrying about it. 😃 Let’s figure out what we can figure out.

Without Calva, I’m useless. The command line is impossible.

Are you using Jack-in to start the repl?

Yes

What’s the jack-in command line? (Calva has a command for copying the jack-in command line to the clipboard).

I can make a short video of what I’m doing if that will help

I think I get what you are doing from the description above. (I had just managed to forget that you used jack-in.) The jack-in command line will show us how to start the repl ourselves.

Ok, I started it on the command line, let me try to connect to it from Calva

Same error

To try to isolate the problem we should get Calva out of the test first. As well as nrepl. So if you paste the jack-in command line here, I will try to edit a command line that will start an interactive repl prompt in the terminal.

clojure -Sdeps ‘{:deps {nrepl/nrepl {:mvn/version,“1.0.0”},cider/cider-nrepl {:mvn/version,“0.28.5"}}}’ -M -m nrepl.cmdline --middleware “[cider.nrepl/cider-middleware]”

this ?

; Starting Jack-in Terminal: pushd /Users/kkamdar/repos/sdp-api/app/smoketests ; clojure -Sdeps '{:deps {nrepl/nrepl {:mvn/version,"1.0.0"},cider/cider-nrepl {:mvn/version,"0.28.5"}}}' -M -m nrepl.cmdline --middleware "[cider.nrepl/cider-middleware]" ; popd

Yes, that. You should be able to start a repl prompt just typing clj on the prompt.

i can do that, but I haven’t been able to figure out how to load the file.

Googling around, its not clear

=> (require 'the.ns.of.the.file)

did that, let me try it again. I also tried (load-file).

Yes, load-file is more like what Calva does.

What you pasted looks strange. Two nested in-ns.

i know. I think the output is just messed up

Yeah. but you are also missing the quote on the namespace. That’s what the error message is about.

same error:

But running it like this:

exec java $JAVA_OPTS \
    -Dfile.encoding=UTF-8 \
    -Dclojure.debug=false \
    -jar /app/smoketests-standalone.jar

works. So maybe its not related to Calva

Yeah, since you get the error without Calva, it means this is not caused by nrepl or Calva.

But related to clj. I can try upgrading to a later version

Ok, thanks Pez, sorry for being a pest. Let me try to update the version

It could also be related to the clj-yaml version. Check in #C042XAQFCCU if someone has an idea what could be going on.

oh ok, let me check there, didn’t know there was a channel for it

It’s natural to start asking here, especially since it works running the standalone jar.
