False positive "unresolved namespace" warning in data_readers.clj

version

clj-kondo v2020.05.09

platform

Native, docker and JVM

problem

From https://clojure.org/reference/reader#tagged_literals

When Clojure starts, it searches for files named data_readers.clj at the root of the classpath. Each such file must contain a Clojure map of symbols, like this:

{foo/bar my.project.foo/bar
 foo/baz my.project/baz}

clj-kondo warns for unresolved namespaces and suggest adding a require.

repro

echo '{foo/bar my.project.foo/bar
 foo/baz my.project/baz}' > data_readers.clj
clj-kondo --lint data_readers.clj
data_readers.clj:1:2: warning: Unresolved namespace foo. Are you missing a require?
data_readers.clj:1:10: warning: Unresolved namespace my.project.foo. Are you missing a require?
data_readers.clj:2:10: warning: Unresolved namespace my.project. Are you missing a require?
linting took 8ms, errors: 0, warnings: 3

expected behavior

No errors/warnings about the foo namespace.

I'm not sure what's the expected behaviour for my.project.foo and my.project warnings. Either a) don't report them or b) check if those vars exist in the project and warn if they don't.

Or maybe just simply disable unresolved namespace linter if the file name is data_readers.clj?

Yes. We do exactly this for project.clj too.

Is there a workaround for this in the meantime, something I could put in my .clj-kondo/config.edn?

Ah, I figured it out. Posting here for anyone else who gets stuck on this:

{:output {:exclude-files ["src/data_readers.clj"]}}
