Funny part is that there is no class files and even the copy of the resource folder isn't in the target folder 😕

with lein the uberjar build works. BUT i wanted to give that method a try cause afaik its the new official way right?

i've a compojure ring app with run/jetty in it and the wrap-reload middleware

and doing a (compile 'jobplatform.core) leads to

Syntax error macroexpanding clojure.core/ns at (jobplatform/core.clj:1:1).
No such file or directory

The very last error is probably because the classes directory is missing. Not the target/classes that your build.clj mentions, but the value of *compile-path*, which by default is just "classes".

Yeah but i have no clue :/ switched to lein and everything works great :/ maybe i'm just to dumb xD

An explicit call to compile won't work with Lein just as well, because it's not about your tools but rather about how compile works.

Ah good to know. You know last time i was investibg into clojure like 5 or 6 years ago there was only lein :D just wanted to expand my knowledge and get back to awesome lisp development

These lines in the output seem to be crucial:

* run-java-tool was invoked directly
* run-java-tool should only be used via symlinks to it

Oh ok i'm on gentoo currently

Btw whats the current state of the art build wise still leiningen or is it allready boot or deps.edn

What's in /tmp/clojure-5265600849608910499.edn ?

I don't think the java thing is an issue or it wouldn't have run at all

The EDN was posted above. Pretty sure it is the issue since the run-java-tool wrapper uses exit 1. Seems the main process was run with one version of Java but compile-clj tried to use that wrapper.

I guess, can also set :java-cmd on the compile-clj task to a specific path to the java executable if needed

ok after setting JAVA_CMD or JAVA_HOME the build is complaining that it can't find clojure.main

even if i add it as dep

can you share the actual output

same error if i use only one of the vars

can you post the /tmp/compile-clj3444501778209445454/compile.args file

/usr/bin/java -cp /tmp/compile-clj3444501778209445454/compile-clj:target/classes clojure.main /tmp/compile-clj3444501778209445454/compile.clj

that is the actual command being run during the compile, you should be able to run it from your project directory at the terminal, not sure you will see anything different, but you could try that

the error makes it seem like clojure is not on the classpath, but I'm not sure how that would be happening. I guess I'm assuming your deps.edn is a typical deps.edn file

is there some example project for a hello world somewhere?

https://clojure.org/guides/tools_build, but seems like you are mostly doing that

for the clojure command i just did the install-linux.sh thing

can i reset that somehow maybe there was an issue

I don't see any reason to believe that's an issue

can you run the command above? or push up this project to git or something

i guess i can upload the hello world thing i did besides that that also doesn't work maybe my java installation doesn't work

correctly but i don't understand why lein is than working for me

You have:

> JAVA_HOME=/opt/openjdk-bin-17.0.10_p7/bin/javac JAVA_CMD=/usr/bin/java ...

> JAVA_HOME=/opt/openjdk-bin-17.0.10_p7 ...

> JAVA_CMD=/opt/openjdk-bin-17.0.10_p7/bin/java ...

i have tried it either way and you are right they java_home javac path was wrong in my paste but i undid that and came to the same clojure.main class not found exception sadly 😕 i don't get it why lein works and deps.edn not 😕 i want to use deps.edn 😄 somehow.

A good opportunity to learn the basics of tracing tools, if you're up for it. :) I'd look any sort of top (`top`, htop, btop, etc.) what exactly lein launches (easier if you put (Thread/sleep 1000000) somewhere). Or use strace with a filter for any syscalls that launch subprocesses. Learning how to view some the env of some process is also useful. All that is pretty basic stuff, easy to look up, even easier with LLMs. And in my case, it's enough to figure out what the hell is going on in around 80% of the cases.

My guess is that lein uses the same exact executable with maybe the same exact env that was used to launch its main process.

I’ll ask again - can you run the command in compile.args? If that doesn’t work, what do you get?

Error: Could not find or load main class clojure.main
Caused by: java.lang.ClassNotFoundException: clojure.main

thats what i get

So somehow the classpath does not include your deps

Don't you need to deref your basis? I see a similar error when using delay without the deref.

Yes! Thank you

That’s probably something I can add a check for

what do you mean by deref?

@basis instead of basis -- look closely at your build.clj and at the guide on http://clojure.org that was linked above.

@ = deref -- since you have (delay ..) in your basis def, you need to deref the delay in order to get the underlying value.

oh my god it was a compination now it works thanks so much guys

so to sum up. On gentoo or any distro that uses run-java-tool you have to set the java runtime as env either JAVA_HOME or in my case JAVA_CMD and as @U04V70XH6 mentioned you have to use @basis in the edn file. I was confused cause on the internet there was plenty of other stuff too. So add your JAVA_CMD and follow the official docs guys. Thanks again

> On gentoo or any distro that uses run-java-tool you have to set the java runtime as env either JAVA_HOME or in my case JAVA_CMD This doesn't sound right, given how tools.build searches for Java. Are you sure your env in a new shell doesn't include any JAVA_ variables?

You may see examples of build.clj that do not have the delay on computing the basis -- in which case those wouldn't deref it at use. Personally, I tend to create the basis inside a function: https://github.com/seancorfield/honeysql/blob/develop/build.clj#L86-L96 and just call that where I specifically need options with a :basis key.

i'll check one minute btw thank you too @U2FRKM4TW and @U064X3EF3

declare -x JAVAC="/home/metti/.gentoo/java-config-2/current-user-vm/bin/javac" thats what there is only

What does env | grep JAVA output?

and what the clojure script does is it uses type -p java which on gentoo gives you the /usr/bin/java which is basically a symlink to run-java-tool

❯ env | grep JAVA
JAVAC=/home/metti/.gentoo/java-config-2/current-user-vm/bin/javac

> which on gentoo gives you the /usr/bin/java which is basically a symlink to run-java-tool That's perfectly fine because run-java-tool specifically asks to be run via a symlink. But somehow it's being used directly.

and setting only JAVA_HOME didn't work either cause it the type command is first

@U2FRKM4TW thats right thats strange

You can also try running your build process in a way that results in that run-java-tool error with (into {} (filter #(clojure.string/starts-with? (key %) "JAVA")) (System/getenv)) printed somewhere inside the script and see what it outputs. Just in case.

{JAVAC /home/metti/.gentoo/java-config-2/current-user-vm/bin/javac}

Ahh, I see. @U064X3EF3 Caused by https://github.com/clojure/tools.build/blob/181ef9c90fd82014e4e44e711e3aec9baefeb3d7/src/main/clojure/clojure/tools/build/tasks/process.clj#L108`.getCanonicalPath` that resolves symlinks.

whats strange is that doesn't the emacs cider mode use clojure to initialize the repl? Cause there everything just works fine.

REPL has nothing to do with all this.

ah ok i see guess its due to the compilation of the code? that you need the right executable than?

No, it's just a combination of that wrapper on Gentoo being very strict with how it's called (for seemingly a good reason - the existence of the wrapper should be left as an implementation detail, nobody should rely on the wrapper directly), and tools.build using .getCanonicalPath, nothing more to that particular error.

don't think anything has changed for that

There's a chance you're thinking about some tool that does that, e.g. Clerk, like described here: https://clojurians.slack.com/archives/C66EM8D5H/p1713893176618759

ok, so i'm crazy. got it 😛

including that metadata on symbols seems like it might be a nice small enhancement

@U053S2W0V I have vague memories of being confused by this a while ago... You experiencing this?:

$ clj
Clojure 1.11.3
user=> (meta '(1 2 3))
{:line 1, :column 8}

aaaah yeah, tools.reader does this

with clojure's default reader:

user=> (map (juxt identity meta) (tree-seq sequential? seq '(1 [x (y)])))
([(1 [x (y)]) {:line 1, :column 71}]
 [1 nil]
 [[x (y)] nil]
 [x nil]
 [(y) {:line 1, :column 77}]
 [y nil])

was expecting to see meta on anything that satisfies IMeta, but was hoping to see it on the symbols at least

I agree this would be useful. There's an Ask about this: https://ask.clojure.org/index.php/13314/location-data-on-all-iobj

Oh, it seems it does and I can use byte/1 instead, and the ordering no longer matters. 🙌

What do you mean ordering?

λ clj -Srepro -M -r
Clojure 1.11.1

P
user=> (extend-protocol P (Class/forName "[B") (m [_] :b) String (m [_] :s))

user=> (extend-protocol P String (m [_] :s) (Class/forName "[B") (m [_] :b))
Syntax error (IllegalArgumentException) compiling at (REPL:1:1).

Clojure 1.12.0-alpha10
user=> (defprotocol P (m [this]))
P
user=> (extend-protocol P String (m [_] :s) byte/1 (m [_] :b))
nil
user=>

In the top form the string is read as a date, then converted to a different string (the bottom arrow), then read again.

Right, and that second printing is different in 1.12.0 from the original input due to how printing of dates is implemented.

Is it just a Clojure printing thing or does Java do something weird too?

I've never tried playing with dates around Gregorian calendar inception 😅

FWIW in Java I get (almost) the last result (different because of time zone I assume)

I don't know what's up with the first two numbers

the only thing that has changed is printing, but we'll take a look

I get -12238560000000 in all three cases.

Forgot to add - Java 21.0.3. @U06PNK4HG On 1.12.0-alpha10?

Still the same with JDK21 and 22, 1.11.3 and 1.12.0-alpha10. MacOS, en_US.UTF-8

Same in Docker

So I assume you also get this with all combinations?

user=> #inst "1582-02-24"
#inst "1582-02-24T00:00:00.000-00:00"

Clojure 1.12.0-alpha10
user=> #inst "1582-02-24"
#inst "1582-03-06T00:00:00.000-00:00"

Clojure 1.11.3
user=> #inst "1582-02-24"
#inst "1582-02-24T00:00:00.000-00:00"

Yes, always #inst "1582-02-24T00:00:00.000-00:00"

Weird. Here's a full unabridged reproduction. Does it also output 1582-02-24 for you? (Should be fine to use docker instead of podman if that's what you usually use).

It's a bit deeper than printing. Or it is about printing, but in the end it influences the #=() expression.

user=> (decompile #inst "1582-02-24")

...
    public static void __init0() {
        const__0 = RT.readString("#inst \"1582-03-26T00:00:00.000-00:00\"");
    }
...

Funny that if you try to decompile that, the read date drifts even further:

(decompile (.getTime #inst "1582-03-26T00:00:00.000-00:00"))

...
    public static void __init0() {
        const__0 = RT.readString("#inst \"1582-04-25T00:00:00.000-00:00\"");
    }
...

This is the change that causes differences in printing, but you probably know that: https://clojure.atlassian.net/browse/CLJ-2803 https://github.com/clojure/clojure/commit/213c50e7a34a27901b6db835b87f840a8b2a36ee

Yeah, it's mentioned in the Ask I link to in the OP.

Yeah, reading is hard.

Huh...
