创建一个用于从 Java/Clojure 执行的 jar 文件 [英] Creating one jar file that for execution from Java/Clojure

问题描述

我想创建一个使用 java 和 clojure 实现的 jar 文件来执行.这是我采取的步骤.

I'd like to create one jar file to execute that is implemented with java and clojure. This is the step that I took.

我可以生成一个包含 clojure 核心和我的 clojure 代码的 jar 文件 (ThingOne-1.0.0-SNAPSHOT-standalone.jar)，我还可以获得一个使用 clojure 代码的类文件 (HelloJava.class)通过关注这个网站 - http://walkwithoutrhythm.net/blog/2012/03/26/how-to-call-clojure-1-dot-3-functions-from-java/

I could generate a jar file (ThingOne-1.0.0-SNAPSHOT-standalone.jar) that has clojure core and my clojure code, and I also could get a class file (HelloJava.class) that uses the clojure code in the jar file by following this site - http://walkwithoutrhythm.net/blog/2012/03/26/how-to-call-clojure-1-dot-3-functions-from-java/

java代码如下:clojure代码导入为ThingOne

The java code is as follows: clojure code is imported as ThingOne

import ThingOne.*;

public class HelloJava {
    public static void main(String[] args) {
        System.out.println("Hello from Java!");
        core.foo (12345);
    }
}

我可以运行这个命令来使用代码:

I can run this command to use the code:

java -cp 'ThingOne-1.0.0-SNAPSHOT-standalone.jar:.' HelloJava

制作一个jar文件

我制作了一个具有这种结构的 jar 目录.

Making one jar file

I made one jar directory that has this structure.

├── MANIFEST.MF
└── jar
    └── ThingOne-1.0.0-SNAPSHOT-standalone.jar

MANIFEST.MF 的内容是

The content of MANIFEST.MF is

Manifest-Version: 0.1
Main-Class: HelloJava
Class-Path: jar/ThingOne-1.0.0-SNAPSHOT-standalone.jar

我可以用 jar cvfm hello.jar jar/MANIFEST.MF HelloJava.class 得到一个 jar 文件.

I could get one jar file with jar cvfm hello.jar jar/MANIFEST.MF HelloJava.class.

但是，clojure jar 文件(ThingOne-1.0.0-SNAPSHOT-standalone.jar)并未包含在此 jar 文件中，而只是引用了.

However, the clojure jar file (ThingOne-1.0.0-SNAPSHOT-standalone.jar) is not included in this jar file, but just referenced.

如何制作一个包含java类文件和clojure jar文件的jar文件?

How can I make one jar file that contains the java class file and clojure jar file?

推荐答案

如果你想制作一个包罗万象的 jar，使用如下工具:

If you want to make an all-inclusive jar, use tools like:

• Jar Jar 链接
• one-JAR™

如果你特别想要打包 jar 文件，你需要一个自定义的类加载器，比如:

If you specifically want to package jar files, you need a custom classloader, like:

• JarClassLoader

也就是说，我会考虑道文的建议，除非您有它无法满足的特定需求.

That said, I'd consider Dao Wen's suggestion, unless you have a specific need it cannot meet.
