java.lang.IllegalArgumentException: Unable to resolve classname: URI

[Ilias Deros]

Getting this error on compilation. Here's my code:

; Import
:dependencies [[org.clojure/clojure "1.7.0"]
               [com.velisco/clj-ftp "0.3.12"]]

; Require
(:require [miner.ftp :as ftp])

; Code
(ftp/with-ftp [client "ftp://user:pwd@host/"]
  (println "Client:" client))

Any idea what is missing to run an ftp pull here?

Full error:

java.lang.IllegalArgumentException: Unable to resolve classname: URI, compiling:(store_worker/sync/products.clj:371:3)
Exception in thread "main" java.lang.IllegalArgumentException: Unable to resolve classname: URI, compiling: ***Line that contains (ftp/with-ftp [client "ftp://user:pwd@host/"]***

Sorry, I don't know what's wrong. URI should refer to java.net.URI, which comes with Java. Can you try to test the clj-ftp project on your machine? Download the project source and run lein test.

Running tests using a fresh project clone:

Ran 13 tests containing 34 assertions.
0 failures, 0 errors.

However, I could reproduce the error by changing the clojure version from 1.8 from 1.7:

Solution

Update project.clj's clojure version to >= 1.8:

[org.clojure/clojure "1.8.0"]
