在Eclipse中生成包含外部库的jar [英] Generating a Jar in Eclipse including external library

问题描述

我有一个我在eclipse中编写的java应用程序。它工作正常。

它可以从导出它的目录中的命令行运行正常。在该目录中是另一个目录，其中包含两个应用程序需要的jar文件，并且清单文件具有指定它们的Class-path选项。

我想要一种方法使用eclipse生成必需的文件来打包这个应用程序以在另一台机器上运行。那可能吗？

如果我选择创建可执行的jar文件，它会创建这个巨大的文件;它解压缩并重新包装了两个库，我知道这是一个方法来实现它们的功能。如果他们作为自己的罐子留下来，我实际上会喜欢它，但是我不确定eclipse可以做到这一点。更令人讨厌的事实是，可执行的jar文件选项将我的eclipse项目中的大量文件放入该jar文件。我没有看到可以选择什么包含在那里，虽然我确实看到一个地方在项目属性中输入包含和排除规则，这些在这里应用吗？还有别的地方去选择什么和做什么没有包含在可执行jar中？

如果我选择创建jar（ins创建可执行jar），我看不到有哪些选项包括这两个jar文件在任何地方，也许没有地方可以包含他们可以使用的地方。

如果可能，我不想使用Ant，我不想使用Maven，我不想下载另一个工具，在我看来，Eclipse已经拥有所有这些信息，我怀疑它已经可以做到这一点，而不用去学习另一个漂亮的工具。 p>

解决方案

Eclipse有自己的Jar导出向导，用于生成包含所需库的可运行jar或将文件夹中所需的库放在jar旁边。

进入文件--->导出，然后选择Java - Runnable Jar

然后，您可以选择如何打包和如何处理库：

你也可以保存蚂蚁脚本供以后修改或使用...

I have a java application I've written in eclipse. It works fine there.

It works fine run from a command line in the directory where I export it to. In that directory is another directory containing two jar files that I need for the application, and the manifest file has a Class-path option specifying them.

I want a way to use eclipse to generate the necessary file(s) to package this application to run on another machine. Is that possible?

If I choose "create executable jar file", it creates this huge file; it does unpack and repack the two libraries, which I know is one way to get their functionality included. I would actually prefer it if they were left as their own jars somehow, but I am not certain eclipse can do that. More annoying is the fact that the executable jar file option puts lots of files from my eclipse project into that jar file. I don't see an option to choose what gets included there, though I do see a place to enter inclusion and exclusion "rules' in the project properties. Do those apply here? Is there somewhere else I go to select what does and does not get included in the "executable jar"?

If I choose "create jar" (ins of "create executable jar"), I don't see where there's an option to include these two jar files anywhere. Perhaps there is no place to include them where they could be used.

If possible, I do not want to use Ant, I do not want to use Maven, I do not want to download another tool. It seems to me that Eclipse already has all this information and I suspect it can already do this without having to go and learn yet another "nifty" tool.

解决方案

Eclipse has its own Jar export wizard for generate a runnable jar packed with required library or with the required library in a folder aside the jar.

Going in File ---> Export then choose Java - Runnable Jar

You can then choose how pack the jar and how handling libraries :

You can also save the ant script for later modification or use ...
