Clojure Can';t使用Leiningen 2.5.2运行uberjar
我本想再次接Clojure,但一开始就绊倒了。我下载了lein,并复制了以下Clojure Can';t使用Leiningen 2.5.2运行uberjar,clojure,leiningen,Clojure,Leiningen,我本想再次接Clojure,但一开始就绊倒了。我下载了lein,并复制了以下project.clj和hello.clj,以确保我有一个最小的工作示例 project.clj: (defproject hello "0.1.0-SNAPSHOT" :description "FIXME: write description" :url "http://example.com/FIXME" :license {:name "Eclipse Public License"
project.clj
和hello.clj
,以确保我有一个最小的工作示例
project.clj:
(defproject hello "0.1.0-SNAPSHOT"
:description "FIXME: write description"
:url "http://example.com/FIXME"
:license {:name "Eclipse Public License"
:url "http://www.eclipse.org/legal/epl-v10.html"}
:dependencies [[org.clojure/clojure "1.7.0"]]
:uberjar {:aot :all}
:main hello.core
)
hello.clj:
(ns hello.core
(:gen-class)
)
(defn -main
"This should be pretty simple."
[]
(println "Hello, World!"))
当我运行“./lein uberjar”时,会收到以下警告:
Warning: specified :main without including it in :aot.
Implicit AOT of :main will be removed in Leiningen 3.0.0.
If you only need AOT for your uberjar, consider adding :aot :all into your
:uberjar profile instead.
Warning: The Main-Class specified does not exist within the jar. It may not be executable as expected. A gen-class directive may be missing in the namespace which contains the main method.
Created .../target/hello-0.1.0-SNAPSHOT.jar
Created .../target/hello-0.1.0-SNAPSHOT-standalone.jar
尝试使用/lein run
或java-jar./target/hello-0.1.0-SNAPSHOT-standalone.jar运行此操作会导致异常:
Can't find 'hello.core' as .class or .clj for lein run: please check the spelling.
Exception in thread "main" java.io.FileNotFoundException: Could not locate hello/core__init.class or hello/core.clj on classpath., compiling:(/private/var/folders/28/bk6d4xj123b0xvsvk91_1jg80009rn/T/form-init1007755193774766954.clj:1:125)
那么我这里的问题是什么呢?:uberjar{:aot:all}->:profiles{:uberjar{:aot:all}
然后将hello.clj移动到./src/hello目录,并将其重命名为core.clj更新:我甚至尝试了一个lein新应用程序
,并将main:app.core
添加到项目中。同样的结果。好的,谢谢!成功了。此外,应用程序模板缺少一个主函数和:gen类。现在我有了所有的拼图项目!
