Warnings related to clojure 1.11 clojure.core/parse- functions when using clojure 1.10.3

version

clj-kondo v2022.03.09

platform

Command line clj-kondo running on Linux archlinux 5.16.14-arch1-1 #1 SMP PREEMPT Fri, 11 Mar 2022 17:40:36 +0000 x86_64 GNU/Linux.

problem

clj-kondo generates warnings about functions like parse-long, parse-double as these are present in clojure 1.11. However, this also happens if a project uses earlier clojure versions (e.g 1.10.3), which do not have these functions.

repro

See sample repository. Supplied lint.sh can be used to build cache and lint.

src/kondo_test/core.clj:4:1: warning: parse-long already refers to #'clojure.core/parse-long
src/kondo_test/core.clj:8:1: warning: parse-double already refers to #'clojure.core/parse-double
src/kondo_test/core.clj:12:1: warning: parse-uuid already refers to #'clojure.core/parse-uuid
src/kondo_test/core.clj:20:13: error: Unresolved symbol: parse-int
linting took 7ms, errors: 1, warnings: 3

expected behavior

No warning should be generated for these functions.

Ah I see yeah. This is probably a won't fix as there is a list of clojure vars built-in independent of version and it's already bumped to 1.11. Just future-proof your repo using :refer-clojure :exclude [parse-long].
