Hello! I occasionally have a weird issue where my repl will just lose references to eval’d namespaces/vars. I’ll get output like this:

; Evaluating file: my_file.clj
; Syntax error compiling at (my/project/directory/structure/my_file.clj:149:7).
; No such var: other-namespace/my-var
; Evaluation of file my_file.clj failed: class clojure.lang.Compiler$CompilerException

So I have to go through a chain of re-evaling namespaces, starting at the bottom until the namespace I am actually working in compiles. Restarting my REPL/Calva fixes this, but it’s randomly annoying. A coworker of mine https://github.com/BetterThanTomorrow/calva/issues/2025 where he suspects the problem originates. I’m posting it here to get some visibility and other possible ideas as to why this happens and how to resolve it.

The problem you describe here sounds the same as https://clojurians.slack.com/archives/CBE668G4R/p1673429735658019 and the thread directly above your post https://clojurians.slack.com/archives/CBE668G4R/p1674113409966499. (No Issue filed yet, that I am aware of. So it would be helpful if you want to write one up.) The Issue you linked to describes difficulty with a custom Jack-in, which does not seem related.

Thanks for the context. The issue I linked is possible adjacent since the afterCLJReplJackInCode in my project calls a start function that loads all the namespaces and dependencies.

I agree with @eveningsky that it sounds like an unlikely connection with that issue. I am known to be wrong often, so there could still be a connection. I have created two tiny projects in the Calva repo: 1. https://github.com/BetterThanTomorrow/calva/tree/dev/test-data/projects/load-bar-requiring-foo (failing to) reproduce the issue you report here, @james.luke.johnson 2. https://github.com/BetterThanTomorrow/calva/tree/dev/test-data/projects/repl-connected-code Reproducing the connect sequence bug your college reported. Please use the first project there to try find a reliable reproduction. I've also created an issue tracking this: https://github.com/BetterThanTomorrow/calva/issues/2026
