There's a trailing space in that string btw

If you really have that, this won't work

it went

!!

sorry

FWIW you do not need shadow.server/start! or stop! when only using release

clojure -T:build socket-repl :port 1337

Unqualified function can't be resolved: socket-repl

clojure -T:build build/socket-repl :port 1337

Namespace could not be loaded: build

deleted .cpcache and ˜/.gitlibs and ran with clj -A:build -M -m build

it gave me

[main] INFO org.eclipse.jetty.util.log - Logging initialized @4872ms to org.eclipse.jetty.util.log.Slf4jLog
Execution error (FileNotFoundException) at build/loading (build.clj:1).

same error 😞

I think the project deps are interfering with your build script and its deps. Use clojure -T:build <function> to invoke functions in build.clj -- they will be passed a single argument, a hash map, like the -X option does.

You'll need the shadow-clj dependency added to :build for that to work -- since your build.clj depends on it and :ns-default build added.

Here's what works:

(obvs it couldn't find the :project build coz I don't have the shadow-cljs config)

my build is in ./src/build.clj is this correct?

or you put into the root folder of the project?

oh, it's in the root folder

thanks @U04V70XH6 it went right 😄

build.clj is not part of your application so it shouldn't live in src. Do you think the tools.build guide could be clearer about that? (and also to use :deps instead of :extra-deps and -T:build instead of -A/`-M` or was that just your attempt to satisfy Cursive?)

I think it needs to be more clear about that

@d.ian.b There's already an issue for this https://github.com/clojure/clojure-site/issues/550 so I've tried to summarize what I think you found confusing/missing there. Feel free to add more comments if I missed anything.

Nice, thanks Sean!

clojure -M:build -m build => I got the Could not locate clojure/tools/build/api__init.class, clojure/tools/build/api.clj or clojure/tools/build/api.cljc on classpath.

again 😞

Clojure CLI version 1.10.3.986

OK, so you could use -T and follow the guide -- which means having an exec function style entry point into your build.clj instead of -main.

I did that to try it on cursive repl only

thanks
