如何建立与蚂蚁一个分发的JAR为Java项目有外部依赖的JAR [英] How to build a distributable jar with Ant for a java project having external jar dependencies

问题描述

我在Eclipse中类的Java项目 MainClass 具有封装主要方法：

I have a Java project in Eclipse with class MainClass having main method in package :

com.nik.mypackage. 

该项目还引用两个外部库，我在Eclipse中的 LIB 文件夹中复制，然后添加使用添加JAR 功能。该库是 one.jar 和 two.jar

The project also references two external libraries, which I copied in the lib folder in Eclipse and then added to build path using ADD JAR function. The libraries being one.jar and two.jar

本库在 LIB 在eclipse文件夹，并添加到构建路径。

This library is in lib folder in eclipse and added to the build path.

我要创建一个使用ant脚本的应用程序的可执行文件 JAR 。这样用户就可以访问我的使用命令的应用程序：

I want to create a executable JAR of the application using ant script. So that user can access my application using command:

c:>java -jar MyProject-20111126.jar

我知道这直接导出一个Java应用程序可运行 JAR 的Eclipse插件。但我想学蚂蚁和构建过程人工手动要创建的build.xm。

I know about the Eclipse plugin which directly exports a java application as runnable JAR. But I want to learn ant and the build process so manually want to create the build.xm.

推荐答案

您从您的build.xml两个选项。您可以不能解压缩的jar包，然后捆绑其内容编译为您的应用code。或者，你可以把文件系统中的jar包，并提供在MyProject的-2011126.jar文件的清单文件中类路径条目。

You have two options from your build.xml. You can either unjar the library jars and then bundle their contents with the code compiled for your application. Or, you can put the library jars on the filesystem and supply a ClassPath entry in the manifest file of the MyProject-2011126.jar file.

如果您设置的类路径在清单记住您提供的路径是相对于MyProject的-2011126.jar。

If you set the classpath in the manifest remember that the path you supply is relative to the MyProject-2011126.jar.
