使用Eclipse for JAR文件自动创建清单文件 [英] Automatically Creating Manifest File with Eclipse for JAR Files

问题描述

如何为已经创建的一组JAR文件创建Manifest文件.

How can I create a Manifest file for a group of JAR file I have already created.

我使用Eclipse创建了JAR文件.

I used Eclipse to create my JAR file.

是否有更好的方法来创建具有Manifest的JAR文件?

Is there any better way of creating a JAR file that has a Manifest?

推荐答案

Eclipse提供了用于为Jar生成清单文件，将生成的清单保存到项目中或为清单使用指定文件的选项.

Eclipse provides options to generate a manifest file for the Jar, save that generated manifest into the project, or use a specified file for the manifest.

我有Eclipse 3.4.2，它在此过程的第四个屏幕上:

I have Eclipse 3.4.2 and it's on the fourth screen in this process:

右键单击项目->导出-> Java/JAR文件，下一步，JAR文件规范，下一步，JAR打包选项，下一步，JAR清单规范.

Right-click Project -> Export -> Java/JAR file, Next, JAR File Specification, Next, JAR Packaging Options, Next, JAR Manifest Specification.

默认情况是仅为JAR生成默认清单，而不是将生成的文件保存回项目，因此，如果打开JAR文件，它将具有清单，但仅包含以下内容: :

The default is to just generate a default manifest for the JAR, and not to save the generated file back to the project, so if you open up your JAR file, it will have a manifest, but it will just have something like:

Manifest-Version: 1.0

在其中.

如果要更改现有的JAR而不重新构建它们，最简单的方法可能就是按照mad-j的建议进行操作，并使用Zip工具打开它们并编辑现有的/META-INF/MANIFEST.MF文件.并将其保存回JAR.

If you want to change your existing JARs without re-building them, the easiest way is probably to just do as mad-j suggested and open them with a Zip tool and edit the existing /META-INF/MANIFEST.MF file and save it back into the JAR.
