Clojure 菜鸟。我无法获得:gen-class
工作的基本示例。
$ lein new app pizza-parlor
; project.clj
(defproject pizza-parlor "0.1.0-SNAPSHOT"
:description "FIXME: write description"
:url "http://example.com/FIXME"
:license {:name "EPL-2.0 OR GPL-2.0-or-later WITH Classpath-exception-2.0"
:url "https://www.eclipse.org/legal/epl-2.0/"}
:dependencies [[org.clojure/clojure "1.10.1"]]
:main ^:skip-aot pizza-parlor.core
:target-path "target/%s"
:profiles {:uberjar {:aot :all
:jvm-opts ["-Dclojure.compiler.direct-linking=true"]}})
; src/pizza_parlor/Deliverator.clj
(ns pizza-parlor.Deliverator
(:gen-class))
(defn -deliver [pizza]
(println "pipin' hot"))
$ lein repl
pizza-parlor.core=> (require 'pizza-parlor.Deliverator)
nil
pizza-parlor.core=> (def d (pizza-parlor.Deliverator.))
Syntax error (ClassNotFoundException) compiling new at (/tmp/form-init10318668819087633543.clj:1:1).
pizza-man.Deliverator
pizza-man.core=> (import pizza-parlor.Deliverator)
Execution error (ClassNotFoundException) at java.net.URLClassLoader/findClass (URLClassLoader.java:435).
pizza-parlor.Deliverator
我已经尝试了:aot
in 的选项project.clj
并运行lein compile
以在 中生成类target/default
,但我得到了同样的错误。
什么是定义 Java 类的正确方法gen-class
,然后在 repl 中与我的项目代码的其余部分一起使用它,或者我可以运行的测试是lein test
什么?
