Clojurians Log v2

Ah, something a bit odd:

(!2016)-> cat ~/.config/clojure/tools/
antq.edn        clj-new.edn     clj-watson.edn  new.edn         tools.edn

TDEPS-268 does sound like a potential cause.

Just hit another weirdness @alexmiller -- if I switch these tools to use the :mvn/version instead of :git/*, the :ns-default from the tool's deps.edn isn't picked up and you have to use the fully-qualified fn name on the CLI. Is that a known limitation of installing tools as Maven deps instead of git deps?

yes

tools rely on getting that from the deps.edn, which is in a well-known place for local and git deps (file at the root of the project). with maven deps, where do you find that? you don't include the deps.edn in the jar typically, and I wouldn't want every jar to have a deps.edn at the root - they would all overlap in classpath space, that's crazy talk. so that is a problem to be solved still

there are several potential answers, have not decided on one

Thanks. Just wanted to make sure -- since I've never used maven deps for tools before. I was only trying that to get rid of the "ambiguous" coords issue.

The problem right now is this:

(!2005)-> ls ~/.config/clojure/tools/
antq.edn  clj-watson.edn  new.edn  tools.edn

(2026-03-05.16:14:51)-(~/clojure)
(!2006)-> clojure -Ttools install-latest :lib com.github.seancorfield/clj-new :as clj-new
clj-new: Installed com.github.seancorfield/clj-new 1.3.415 {:mvn/version "1.3.415"}

(2026-03-05.16:14:58)-(~/clojure)
(!2007)-> cat ~/.config/clojure/tools/clj-new.edn
{:lib com.github.seancorfield/clj-new, :coord {:mvn/version "1.3.415"}}

Is fixing tools.tools a priority? And can I help?

I'm working on it

LMK if I can help/test stuff/whatever 🙂

I released a new tools.tools - you can test it by updating your existing $CACHE/tools/tools.edn:

{:lib io.github.clojure/tools.tools
 :coord {:git/tag "v0.3.6"
         :git/sha "b35ee5b6defd5c3cf15ed052e0cd7a063c0e1379"}}

if that looks good, I'll do a CLI release

Trying it now.

Are you sure about that tag/sha? I get

Error building classpath. Library io.github.clojure/tools.tools has sha and tag that point to different commits

Looks like that SHA should be "b67e68d"?

oh, maybe I grabbed the 0.3.5

yeah, b67e68d2e0bdb540be736c4c442dc8de579766da

sorry, copy/pasted wrong thing

It solves the ambiguous coords issue but still won't install a lib from scratch:

(!2007)-> clojure -Ttools install-latest :lib com.github.seancorfield/clj-new :as clj-new
clj-new: Did not find versions for com.github.seancorfield/clj-new

ok, let me look at that next

I'll keep an eye on Slack and test any new versions.

Related experience report: :ns-default not applied when a tool is installed from Maven https://github.com/liquidz/antq/issues/298

https://github.com/liquidz/antq/issues/298#issuecomment-4170777658, install-latest downloads the git version by default, instead of the Maven version.

re :ns-default - this is a known issue as there is no deps.edn to source the :tools/usage info from in a jar. Tracking in https://clojure.atlassian.net/browse/TDEPS-277 - I think I've settled on what to do there but haven't done it yet.

@alexmiller Am I understanding correctly that there are essentially two parts to that: • A "standard" location to look in a JAR file for a project's deps.edn so that clojure -T can find it and figure out :ns-default etc., • Changes to how tools maintainers build JARs for Maven/Clojars, to ensure they create that file path and copy deps.edn to it (I'm a little hazy on how/where the pom.xml file is copied to the "standard" location under META-INF as it is)

Yes on both. The pom files that get bundled into jar files now is just a maven convention that many build tools follow.

I think in Java land, that copying is done by the maven jar plugin, but merely as a convention

I guess I forgot the announcement on the CLI. I did put it on the release page https://clojure.org/releases/tools#v1.12.4.1612

The other, nothing new that I'm aware of. Examples?

Pick any tool that has both Clojars releases and (previously) git deps -- antq or clj-new were the two where I ran into this. Update the tools/*.edn manually to use the :git/tag and :git/sha for a release that also exists on Clojars. Then try to install-latest. That used to work and it would select a more recent git dep version. Now it finds the Clojars (`:mvn/version`) and says they are ambiguous.

Repro:

(!2010)-> cat ~/.config/clojure/tools/antq.edn
{:lib com.github.liquidz/antq,
 :coord {:git/tag "2.11.1269"
         :git/sha "9d78d7a"
         :git/url ""}}

(!2011)-> clojure -Ttools install-latest
Checking out:  at b35ee5b6defd5c3cf15ed052e0cd7a063c0e1379
Downloading: com/github/liquidz/antq/maven-metadata.xml from clojars
antq: Failed: Coord type is ambiguous: {:git/tag "2.11.1269", :git/sha "9d78d7a", :git/url "", :mvn/version "2.11.1276"}

I'll look into it

Can't think of anything even adjacent to that that's changed in a while

I typically run install-latest every week, so it must be a fairly recent change (and I update all my deps based on clojure -Tantq outdated at least once a week too). I was surprised to see it with clj-new because that hasn't been updated in ages.

I can repro this as far back as 1.12.4.1597 and I suspect it's related to the tools.tools update in that release with https://clojure.atlassian.net/browse/TDEPS-268 but I'll try to verify that tomorrow. I'm wondering if this is could be a flaw in the installation/update of the ~/.clojure/tools/tools.edn where an old version is retained? is this the windows installer from deps.clj or one of the linux or mac installers?
