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jar文件来执行，这是用java和clojure实现的。这是我采取的步骤。

让我的java代码调用clojure代码

文件（ThingOne-1.0.0-SNAPSHOT-standalone.jar），它有clojure核心和我的clojure代码，我也可以得到一个类文件（HelloJava.class）使用clojure代码在jar文件通过跟随这个网站 - http： //walkwithouthrhythm.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

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

我可以运行此命令使用代码： / p>

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

创建一个jar文件

我创建了一个具有此结构的jar目录。

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

MANIFEST.MF的内容是

  Manifest-Version：0.1 
主类：HelloJava 
类路径：jar / ThingOne- 1.0.0-SNAPSHOT- jar 
  

我可以得到一个jar文件 jar cvfm hello.jar jar /但是，clojure jar文件（ThingOne-1.0.0-SNAPSHOT-standalone.jar）不是一个可执行文件

如何创建一个包含java类文件和clojure jar文件的jar文件？

解决方案

如果要创建一个包容性的jar，请使用以下工具：

• Jar Jar链接


• < a href =http://one-jar.sourceforge.net/ =nofollow> one-JAR™

如果您特意要打包jar文件，您需要一个自定义类加载器，例如：

• JarClassLoader

也就是说，我会考虑道文的建议，除非你有特定的需求，它不能满足。

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

Making my java code call clojure code

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/

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);
    }
}

I can run this command to use the code:

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

Making one jar file

I made one jar directory that has this structure.

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

The content of MANIFEST.MF is

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

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

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

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

解决方案

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

• Jar Jar Links
• one-JAR™

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

• JarClassLoader

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