将一个版本合并到一个 JAR 文件中的最简单方法 [英] Easiest way to merge a release into one JAR file

问题描述

是否有工具或脚本可以轻松合并一堆 JAR 文件成一个 JAR 文件?一个好处是可以轻松设置主文件清单并使其可执行.

Is there a tool or script which easily merges a bunch of JAR files into one JAR file? A bonus would be to easily set the main-file manifest and make it executable.

具体案例是Java重组文本工具.我想用类似的东西运行它:

The concrete case is a Java restructured text tool. I would like to run it with something like:

java -jar rst.jar

java -jar rst.jar

据我所知，它没有依赖项，这表明它不应该是一个简单的单文件工具，但下载的 ZIP 文件包含很多库.

As far as I can tell, it has no dependencies which indicates that it shouldn't be an easy single-file tool, but the downloaded ZIP file contains a lot of libraries.

如您所见，最好不需要手动执行此操作.

As you can see, it is somewhat desirable to not need to do this manually.

到目前为止，我只尝试过 AutoJar 和 ProGuard，这两个都相当容易运行.JAR 文件中的常量池似乎存在一些问题.

So far I've only tried AutoJar and ProGuard, both of which were fairly easy to get running. It appears that there's some issue with the constant pool in the JAR files.

显然 jrst 有点坏了，所以我会努力修复它.Maven pom.xml 文件显然也被破坏了，所以我我必须在修复 jrst 之前修复它......我感觉像个错误磁铁:-)

Apparently jrst is slightly broken, so I'll make a go of fixing it. The Maven pom.xml file was apparently broken too, so I'll have to fix that before fixing jrst ... I feel like a bug-magnet :-)

更新:我从来没有时间修复这个应用程序，但我检查了 Eclipse 的Runnable JAR 导出向导"，它基于一个胖 JAR.我发现这很容易用于部署我自己的代码.

Update: I never got around to fixing this application, but I checked out Eclipse's "Runnable JAR export wizard" which is based on a fat JAR. I found this very easy to use for deploying my own code.

其他一些优秀的建议可能更适合在非 Eclipse 环境中构建，oss 可能应该使用 蚂蚁.(Maven，到目前为止只是让我感到痛苦，但其他人喜欢它.)

Some of the other excellent suggestions might be better for builds in a non-Eclipse environment, oss probably should make a nice build using Ant. (Maven, so far has just given me pain, but others love it.)

推荐答案

Eclipse 3.4 JDT 的 Runnable JAR 导出向导.

Eclipse 3.4 JDT's Runnable JAR export wizard.

在 Eclipse 3.5 中，这已得到扩展.现在，您可以选择处理引用的 JAR 文件的方式.

In Eclipse 3.5, this has been extended. Now you can chose how you want to treat your referenced JAR files.
