Which version of lein?

I'm getting the same error too in a deps.edn project since upgrading to latest version of cider

problem seems to be the change in cider-latest-middleware-version

bumping it back down to "0.21.2-SNAPSHOT" solved the error

its a deps.edn project..

When I run the command that emacs/cider says it is running, aka

$ /usr/local/bin/clojure -Sdeps '{:deps {nrepl {:mvn/version "0.6.0"} cider/cider-nrepl {:mvn/version "0.22.0-SNAPSHOT"}}}' -m nrepl.cmdline --middleware '["cider.nrepl/cider-middleware"]'

I get the same error,

Hmm, I did push a new snapshot on cider-nrepl a day ago, but there were no changes there that seem related to this problem.

In particular pr_values was already removed for a couple of months already.

I wonder if something’s wrong with the build in general. It’s the first one using the new MrAnderson 0.5, but on the other hand you’re getting the error for something that’s not even inlined.

seen the issue @bozhidar will have a look later today

the cider.nrepl ns in that snapshot jar looks very outdated. no idea how could that happen. was this a manual build or CI produced?

@benedek - Manual build, done with make deploy.

sorry for asking the obvious. are you sure you run that from the right dir?

not some old backup or something?

Pretty sure about this. 🙂

The deps here match those in HEAD.

run make clean && make install jar has to OK looking cider.nrepl in it

no reference to pr-values

an other weird thing i noticed with the snapshot in question: it has a src dir in it

which maybe has the right version of stuff in it?! looks weird… something went wrong when this was built. what about just trying to deploy a new one maybe?

That’s what I just did.

Did make clean and make deploy again and it seems that this time it’s ok.

Perhaps the previous one got messed up because I didn’t do clean after updating MrAnderson. I don’t know what exactly went wrong, but it seems we’re back in business now.

good, i’ve also seen you already upgraded to 0.5.1-snapshot of MrAnderson. brave move 😉

i just ran make install and i seem to have a src file in the built jar

?!

this is just a bit of it

so what is the difference between me running it and you running it is the big Q

same if you run make clean before? — should not have an effect either tho…

i have two copies it seems. everything at cider/nrepl/ and src/cider/nrepl/

i did not do a clean before but i'll do it now and rebuild

that is what i am seeing in the broken snapshot jar too

lein 2.9.1 on fedora 29.

interestingly (frustratingly?) a lein clean and rebuilding seems to have fixed it

also i run make install without clean this time. result seems to be ok

so seems like the first build is busted and subsequent ones are fine?

strange. there's a top level project.clj in the jar with (defproject mvxcvi/arrangement "1.1.1"

that is just MrAnderson weirdness. should not cause any probs

i mean the project.clj

i can successfully jack in with my installed cider-nrepl

This seems spooky... I tried changing nrepl {:mvn/version "0.6.0"} to *nrepl {:mvn/version "0.6.0-SNAPSHOT"} and it started up fine, now the spooky bit

did you update cider?

when I change it back to "0.6.0" it starts up fine. (without the -SNAPSHOT)

it starts up or doesn't start up?

@bozhidar pushed a change to make CIDER use the 21.2 snapshot. perhaps you have that change?

I was using outside of cider,

$ /usr/local/bin/clojure -Sdeps '{:deps {nrepl {:mvn/version "0.6.0"} cider/cider-nrepl {:mvn/version "0.22.0-SNAPSHOT"}}}' -m nrepl.cmdline --middleware '["cider.nrepl/cider-middleware"]'

ah

oh. i think he also deployed again so it should be fixed

Huh...

Odd, that it didnt download the packages that it needs

in other news will very likely release MrAnderson 0.5.1 tmrw first thing

In that vein, if I remove "-SNAPSHOT" from the cider-nrepl,

$ /usr/local/bin/clojure -Sdeps '{:deps {nrepl {:mvn/version "0.6.0"} cider/cider-nrepl {:mvn/version "0.22.0"}}}' -m nrepl.cmdline --middleware '["cider.nrepl/cider-middleware"]'

oh, I see MrAnderson is supposed to bundle stuff, so this resolution isnt needed.

yes there is no 0.22.0. it is in development there has been no release

huh, so it is an oversight that cider runs with that on the command?

i don't follow. CIDER should never reference 0.22.0 non-snapshot

does it currently?

Humm... Seems I mistakingly installed "CIDER 0.22.0snapshot (package: 20190329.1924)"

I presume I do not want a snapshot version.

cider is an installed package.

     Status: Installed in ‘cider-20190329.1924/’ (unsigned). Delete

up to you. the snapshot version has the chance for breakages (as seen today) but if no one uses it then the melpa-stable version just shifts the risk to everyone rather than volunteers who run the melpa (snapshot) version

ie, if no one beta tests, then everyone beta tests

ok, then I guess I'm wondering then, why does cider have a snapshot mvn dependency

oh, I didnt show that.

presumably you are running the melpa (not melpa-stable) version so you are in the snapshot version

i wish the names were inverted. ie, melpa and melpa-beta or something but it is what it is

Just to be clear, when I execute from emacs, "cider-jack-in", emacs puts this in Messages

[nREPL] Starting server via /usr/local/bin/clojure -Sdeps '{:deps {nrepl {:mvn/version "0.6.0"} cider/cider-nrepl {:mvn/version "0.22.0-SNAPSHOT"}}}' -m nrepl.cmdline --middleware '["cider.nrepl/cider-middleware"]'...

is that legit? or a bug?

seems legit

oh I see ( I read up on SNAPSHOT and maven), snapshot in maven speak means always fetch the latest.

but you also said 0.22.0 has never been released

due to this: https://github.com/clojure-emacs/cider/blob/master/cider.el#L405

the way its released is while you are creating 0.22.0 you release 0.22.0-SNAPSHOT and then once you are happy with it you release the 0.22.0 artifact

so there can be versions of 0.22.0-snapshot while you work on it and it changes and then a single 0.22.0 release

replace snapshot with "beta" "preview" or "test" in your head and it should make sense.

ok, I dropped back to melpa-stable - for today anyway. And all is right with the cider-jack-in

Thanks @dpsutton!!!!! 🙂
