This says import the File class from the package java.io
(ns test (:import (java.io.File)))
Try:
(ns test (:import java.io.File))
(let [filename (first *command-line-args*)]
(println filename)
(let [file (File. filename)])))
I get an
"Reflection warning, X:\workspace\ClojureTest\bin\test.clj:9 - call to
java.io.File ctor can't be resolved."
which I also don't understand.
Clojure relies on type hints to avoid reflection - introspecting Java
class types to figure out calls. If you add ^String in let binding for
filename, it should remove the warning:
(let [^String filename (first *command-line-args*)] ...
HTH?
