Calva Error "LSP classpath lookup failed when running `lein with-profile +test,+dev classpath`. "

[rajcspsg]

I would like to use vs code as development environment for clojure.

I'm opening guestbook project in vs code.

As soon as the project is opened in vs code I get error pop up.

LSP classpath lookup failed when running `lein with-profile +test,+dev classpath`. Some features may not work properly if ignored. Error: Cannot run program "lein" (in directory "/Users/rnatarajan/Documents/Coding/others/clj-web-dev/c01/guestbook"): error=2, No such file or directory Choose an option:

Screenshot here

I'm also getting below details in VS code output -

Same question I've asked in stackoverflow as well

Welcome to Calva!

What I'm pretty sure is happening is you don't have lein installed and/or on your system path. That project contains a project.clj file, which means it's intended to be used with Leiningen. Once you install Leiningen (lein), and add it to your path, reload the VS Code window (if it's still open), and you should no longer see that error.

You're getting that error because Calva uses clojure-lsp for static code analysis features. When clojure-lsp is starting up for that project, it's trying to run that lein command in your screenshot to get some info it uses.

Let me know if the above suggestion works for you or if you have any further troubles.

@bpringe which lein returns /Users/rnatarajan/.sdkman/candidates/leiningen/current/bin/lein and echo $PATH returns

/Users/rnatarajan/.cabal/bin:/Users/rnatarajan/.ghcup/bin:/Users/rnatarajan/.sdkman/candidates/sbt/current/bin:/Users/rnatarajan/.sdkman/candidates/maven/current/bin:/Users/rnatarajan/.sdkman/candidates/leiningen/current/bin:/Users/rnatarajan/.sdkman/candidates/java/current/bin:/Users/rnatarajan/.sdkman/candidates/gradle/current/bin:/Users/rnatarajan/.elixir-ls/:/Users/rnatarajan/Library/Python/3.9/bin:/Users/rnatarajan/Documents/Coding/ekata/home-bin:/Users/rnatarajan/.bin:/opt/homebrew/bin:/opt/homebrew/Cellar/pyenv-virtualenv/1.2.1/shims:/Users/rnatarajan/.pyenv/shims:/opt/homebrew/bin:/usr/local/bin:/System/Cryptexes/App/usr/bin:/usr/bin:/bin:/usr/sbin:/sbin:/Users/rnatarajan/.cargo/bin:/Users/rnatarajan/Library/Application Support/Coursier/bin:/Users/rnatarajan/Library/Application Support/Coursier/bin:/Users/rnatarajan/.roswell/bin

The lein /Users/rnatarajan/.sdkman/candidates/leiningen/current/bin is already in the PATH.

Not sure if I miss anything

Hmm. Sometimes even though something is on your path in your terminal, it's not found in an integrated VS Code terminal when you open VS Code outside of that terminal (like by clicking the application). I'm not positive that's what's going on here since clojure-lsp is a separate process that's trying to run lein, but when you're in VS Code, can you run lein with-profile +test,+dev classpath successfully?

If not, try opening VS Code from a terminal where lein is found, using code <relative path to project directory>, and see if the problem persists.

Also, if the problem persists, please copy and paste the contents of your clojure-lsp server log here. CC @ericdallo

I don't know how to get clojure-lsp server logs.

I've lein installed and accessible via konsole.

I opened the vs code from same konsole via command open -a /Applications/Visual\ Studio\ Code.app. Still I get the same error.

The calva open lsp log provides only the below info which I think is not useful. I have enabled the verbose mode as well.

That's a bug. It should open the clojure-lsp log file. But you can open it manually. If you use the Show Server Info command instead, you should see the log-path printed (amongst a lot of other info), something like:

"log-path": "/tmp/clojure-lsp.out",

Then you can open this in VS Code from the command line. For the above path:

code /tmp/clojure-lsp.out

Thanks @PEZ

Here is the clojore-lsp server log.

But I doesn'tn't say why I doesn't find lein though

[ericdallo]

@rajcspsg are you on windows? we have this custom logic to convert the command to use powershell, maybe could be related?

[ericdallo]

ah nvm, the log says it's running lein with-profile +test,+dev classpath indeed

[ericdallo]

if lein is really on PATH, it should work
