For some reason cider-connect is now auto-filling the wrong port for a server I started with lein repl :headless.

Has anyone seen that kind of behavior before?

Is there a way to avoid the recent javax.xml.bind exception when starting up a cider repl? https://dev.clojure.org/jira/browse/CLJS-2377

I see that there are some args that you can add in the repl command line, but I don’t know about Cider/Spacemacs

To be accurate; when I start a Cider cljs repl, I get the following exception:

2. Unhandled clojure.lang.Compiler$CompilerException

i'm seeing

(defcustom cider-lein-global-options
  nil
  "Command global options used to execute Leiningen (e.g.: -o for offline)."
  :type 'string
  :group 'cider
  :safe #'stringp)

you could set that to "--add-modules java.xml.bind"

no idea if that will work but that's where i would start

how do I do that?

I’m not handy with elisp

ah ok

(setq cider-lein-global-options “--add-modules java.xml.bind”)

?

that's one way but that will be "global"

you can look into dir-locals, which will only apply under a particular directory structure

but if this is a jdk thing it sounds like it should be global?

maybe it’s OK that they’re global? 🙂

I’ll just give it a go

sounds good

feedback in a min

and you'll probably want that in your init so it is persisted

apparently I don’t know how to add it properly to my .spacemacs

tried both init and config

You could also set in the top level of the project that needs this a file called .dir-locals.el with the content

((nil . ((cider-lein-global-options . "--add-modules java.xml.bind"))))

^^^ this way, when checked in, it will work for anyone else using the project and emacs as well

wait

hmmm

error in process sentinel: Could not start nREPL server: ‘--add-modules’ is not a task. See ‘lein \
help’.

oh. we're feeding lein the java options. i think there's a way to do this

@tanzoniteblack I’ll try your approach

:jvm-opts ["-Xmx1g" "-server"]

i think we are fundamentally in the wrong area

we need clj optionsin project, not elisp

^^^ Agreed, didn't realize this was a javac option

add to your jvm-opts vector "--add-modules=java.xml.bind" (or whatever the exact appropriate thing is) inside your project.clj

although you could look to see how cider slides in cider-nrepl and try to emulate that

so that this fix would happen for all of your projects until the fundamental fix is applied

else you will have to edit every project.clj file you use

I’m expecting the fix to go in soon, maybe foolishly. This is just for my hobby projects (until the same thing occurs at work, of course ; ) so I’ll live with the project.clj changes

let me give it a go

where do I put it in my project.clj?

don’t have a :jvm-opts key there already

cheers

great success! 😄 😄 😄

Thank you so much, @dpsutton @tanzoniteblack!
