something weird going on since yesterday, starting a repl with cider I get

Caused by: java.lang.IllegalAccessError: reader-error does not exist

    clojure.core$apply.invokeStatic (core.clj:667)

works fine if I do lein repl from the terminal, anyone else seeing this?

I'm on CIDER 0.24.0snapshot (package: )

Hmm. Funny. I've just tried to start our app and suddenly getting this error when I try to run cider-jack-in :

error in process sentinel: Could not start nREPL server: clojure.lang.Compiler$CompilerException: Syntax error compiling at (clojure/tools/reader/edn.clj:41:7).
#:clojure.error{:phase :compile-syntax-check, :line 41, :column 7, :source "clojure/tools/reader/edn.clj"}

...

[org.clojure/tools.reader "1.3.2"]

I've found this one: https://github.com/clojure-emacs/cider/issues/2236 But they say adding an explicit dependency on tools.reader did help them

ah right I'm not the only one then, and doesn't actually happen in all the projects either

I cleared also everything I had in my lein profiles just to be sure

And still the same error?

yes same thing

also adding tools.reader as dependency doesn't help

starting the repl from the terminal and doing cider-connect works

so definitively one of the libraries used in the cider startup is acting funny

I get the same problem with an open source project btw: https://github.com/FundingCircle/topology-grapher/ if anyone else could give it a try, I'll file an issue in the meanwhile or reopen that same one?

I just tried even starting with Emacs -Q with 0 config and it's the same problem

Do you have refactor installed?

yes

clj-refactor is an installed package. Status: Installed in ‘clj-refactor-20191217.909/’ (unsigned). Version: 20191217.909

should I try to delete that?

mm no same thing after I delete it

strange thing is that everything was working fine until a few days ago, but I don't even see any suspicious commit recently

Yep, the same for me too. I had older cider release from september so I tried to upgrade but the issue remains even with the latest version

is the full lein command printed somewhere apart from the minibuffer? it doesn't go to Messages, would be nice to see that

trying to run it without some arguments

It goes to messages 😉

I get further if I exclude the refactor-nrepl plugin but then it freezes before the repl prompt shows up:

Instrumented specs
nREPL server started on port 57012 on host localhost - 

# and then nothing ...

Btw. you can customize that via prefix, e.g. C-u , ' But that doesn't help anyway in this case 🙂

Btw. I'm using spacemacs

well for me it works with the full command from the shell

$ /usr/local/bin/lein update-in :dependencies conj \[nrepl\ \"0.6.0\"\] -- update-in :plugins conj \[refactor-nrepl\ \"2.5.0-SNAPSHOT\"\] -- update-in :plugins conj \[cider/cider-nrepl\ \"0.23.0-SNAPSHOT\"\] -- repl

ah the reason why I don't see it in Messages is that the buffer size is too small

and I lose that message 😄

message-buffer-max-lines should help

Ah, that's interesting. For me the error is basically the same regardless if I run it from Cider or from cmd - it's weird that it's different for you; But then I experience a slightly different issue:

clojure.lang.Compiler$CompilerException: Syntax error compiling at (clojure/tools/reader/edn.clj:41:7).
#:clojure.error{:phase :compile-syntax-check, :line 41, :column 7, :source "clojure/tools/reader/edn.clj"}

ok yeah anyway it's definitively refactor-nrepl somehow, I reproduced it also in the shell now

no I think it's the same error

I was testing on another project, in that project it didn't actually fail

I tried refactor-nrepl 2.4.0 but it freezes in a similar way as if I try to exclude it completely

Yep, other (simpler) project works for me too

I have tons of dependencies so it's hard to tell....

maybe one of these changes

to me this command works /usr/local/bin/lein update-in :dependencies conj \[nrepl\ \"0.6.0\"\] -- update-in :plugins conj \[refactor-nrepl\ \"2.4.0\"\] -- update-in :plugins conj \[com.billpiel/sayid\ \"0.0.18\"\] -- update-in :plugins conj \[cider/cider-nrepl\ \"0.23.0-SNAPSHOT\"\] -- repl :headless :host localhost, so using 2.4.0 for refactor-nrepl

so yeah definitively that, can I just disable it entirely somehow?

@bozhidar could it be some recent change to https://clojars.org/refactor-nrepl/versions/2.5.0-SNAPSHOT ?

I would guess it's in one of https://clojurians.slack.com/archives/C0617A8PQ/p1577098713041900

I can't find how to disable refactor-nrepl entirely or at least pin it to 0.24 btw

I've tried to build my own version but ./build.sh install failed (`Caused by: http://java.io.FileNotFoundException: Could not locate clojure/spec/alpha__init.class or clojure/spec/alpha.clj on classpath.`)

probably too old version of clojure?

lein do clean, install works but I'm not sure that's the proper way to do it

I created this issue in the meanwhile https://github.com/clojure-emacs/refactor-nrepl/issues/283

after a bit of bisecting this is the commit that broke it https://github.com/clojure-emacs/refactor-nrepl/commit/75f5255f0e4e701f50d30cc58216e03c2d558905

if anyone wants a workaround in the meanwhile just: • checkout locally the refactor-nrepl project • git checkout e35af1d1b972cfecbf5e857384234ac3f683652d to get to a working version • lein install to install it in your maven dir (overriding the 2.5.0-SNAPSHOT that would be downloaded)

with that it should all work locally (at least it does for me)
