ANT 读取现有的 MANIFEST 版本并附加到它 [英] ANT read existing MANIFEST version and append to it

问题描述

我需要编写一个 ant 构建脚本，该构建脚本从 META-INF/manifest.mf 文件中读取现有版本并将其附加到该文件中.

I need to script an ant build which reads in the existing version from a META-INF/manifest.mf file and appends to it.

应该可以使用 ANT manifest 任务进行更新，但是我无法阅读现有版本.

The updating should be possible using the ANT manifest task, however I've had trouble reading the existing version.

由于清单条目使用 key: value 而不是 key= value 我无法读取它们使用 ANT 的 loadproperties 任务.

As the manifest entries are use key: value rather than key= value I cant read them in using ANT's loadproperties task.

有人这样做过/有什么想法吗?

Has anyone done this/ have any ideas?

谢谢

推荐答案

任务应该完全符合您的要求.它将新的 Manifest key=value 对附加到现有的 Manifest.知道为什么你不能使用它吗?

The <manifest> task should do exactly what you want. It will append new Manifest key=value pairs to an existing Manifest. Any idea why you can't use it?

您可以将 任务与各种过滤器阅读器一起使用，然后使用 任务加载结果.它需要一些肘部润滑脂，但它可能是一种以这种方式读取损坏 Manifest 文件的方法，获取值，然后用这些旧值重写一个新的 Manifest 文件.

You can use the <concat> task with the various filter readers, and then load the result with the <loadproperties> task. It takes a bit of elbow grease, but it might be a way to read in your damaged Manifest file this way, get the values, and then rewrite a new Manifest file with those old values.

我必须查看您现有 Manifest 的示例以及您要向其中添加的内容，以便准确确定您需要什么.

I'd have to see a sample of your existing Manifest and what you want to add to it in order to figure out exactly what you need.
