Dependency [de-dupe "0.2.2"] not found

[jiangts]

I included [de-dupe "0.2.2"] as a dependency in my project.clj and got

Could not find artifact de-dupe:de-dupe:jar:0.2.2 in central (https://repo1.maven.org/maven2/)
Could not find artifact de-dupe:de-dupe:jar:0.2.2 in clojars (https://clojars.org/repo/)
This could be due to a typo in :dependencies or network issues.
