Failure handling version ranges

[mfikes]

If a project specifies version ranges, you can end up with an error like

clojure.lang.ExceptionInfo: Unable to resolve org.clojure/clojure version: [1.2.0,)
{:lib org.clojure/clojure, :coord #:mvn{:version "[1.2.0,)"}}
 at clojure.tools.deps.alpha.extensions.maven$eval1008$fn__1011.invoke (maven.clj:54)
    clojure.lang.MultiFn.invoke (MultiFn.java:239)
    clojure.tools.deps.alpha$canonicalize_deps$fn__1351.invoke (alpha.clj:74)
...

Repro:

project.clj:

(defproject foo "1.0.0"
  :plugins [[lein-tools-deps "0.4.5"]]
  :middleware [lein-tools-deps.plugin/resolve-dependencies-with-deps-edn]
  :lein-tools-deps/config {:config-files [:install :user :project]})

deps.edn:

{:deps {net.cgrand/regex {:mvn/version "1.1.0"}}}

Then do lein deps. Note, that for this setup clj -Stree succeeds.

This regressed with the 1.10.1.455 release of Clojure tools.

If you instead use 1.10.1.447, you and do lein deps you will get

WARNING!!! version ranges found for:
[net.cgrand/regex "1.1.0"] -> [org.clojure/clojure "[1.2.0,)"]
Consider using [net.cgrand/regex "1.1.0" :exclusions [org.clojure/clojure]].

Note, to install and switch between different versions of the Clojure tools, I found this SO helpful: https://stackoverflow.com/a/55764594

Hi @mfikes,

Thanks for the report. I'm not quite clear on what you're saying though. Are you saying that by downgrading the command line tools version to 1.10.1.447 you fixed this issue; but running with 1.10.1.455 causes it to break?

i.e. is your point that this is not a bug with lein-tools-deps but with tools.deps itself, or are you saying this is a bug in lein-tools-deps?

@RickMoynihan I'm just saying that, if you depend on a project that uses version ranges, the ability to do lein deps broke. (Not saying where the error lies.) But, having said that, the ability to do clj -Stree continues to work.
