Cool, thanks for testing!

Can I specify version ranges in deps.edn for dependencies?

no

@janne.sauvala Yes, you can, but you shouldn't. The string used for the version in :mvn/version is just passed through to the underlying library, e.g.,

(! 1176)-> clj -Sdeps '{:deps {hiccup {:mvn/version "(,1)"}}}'
DEPRECATED: Libs must be qualified, change hiccup => hiccup/hiccup 
Downloading: hiccup/hiccup/1.0.0-SNAPSHOT/maven-metadata.xml from clojars
Downloading: hiccup/hiccup/1.0.0-SNAPSHOT/hiccup-1.0.0-20120218.070543-1.pom from clojars
Downloading: hiccup/hiccup/1.0.0-SNAPSHOT/hiccup-1.0.0-20120218.070543-1.jar from clojars
Clojure 1.10.1

Current version is 1.0.5 but you can get the highest version below that

(! 1177)-> clj -Sdeps '{:deps {hiccup {:mvn/version "(,1.0.5)"}}}'
DEPRECATED: Libs must be qualified, change hiccup => hiccup/hiccup 
Downloading: hiccup/hiccup/maven-metadata.xml from clojars

^ @vlaaad FYI

it's not actually passed through, it's resolved in canonicalization to the max in range

but a) version ranges have many known weirdnesses and b) as a non-specific version, they also break clj's caching (you will retain the same cached classpath even if newer versions become available)

Interesting to see it works, thanks @seancorfield! I realized I haven’t seen anyone using version ranges so I was wondering were those intentionally not supported

they are officially not supported

but unofficially handled because they exist in the wild, particularly with transitive deps

@alexmiller Good to know re: canonicalization -- I passed in a bad range and the exception came from Aether so I assumed it was just being passed through. My bad:

Unbounded version range (1,
org.eclipse.aether.resolution.VersionRangeResolutionException: Failed to resolve version range for hiccup:hiccup:jar:(1,: Unbounded version range (1,

	at org.eclipse.aether.internal.impl.DefaultRepositorySystem.resolveVersionRange(DefaultRepositorySystem.java:247)

> I haven’t seen anyone using version ranges Because they're bad and folks avoid them 🙂

well the resolution happens via aether

I think if you had more of stack, you'd probably see canonicalize in there somewhere

Yes. Too bad I have seen them used quite a lot in npm and python world. It is good that bad practice hasn’t polluted clojure community 🙂
