问题描述

限时送ChatGPT账号..

我目前正在这样做:

<jar update="yes"
     jarfile="${pwd}/dist/${release}_installer.jar">
   <zipfileset src="${pwd}/dist/app.jar" includes="com/izforge/izpack/panels/**"/>
   <zipfileset src="${pwd}/dist/app.jar" includes="com/xyz/img/logo.png"/>
</jar>

我现有的安装程序 JAR 得到更新，以根据需要包含从应用 JAR 中提取的文件.

My existing installer JAR gets updated to include the files as needed, extracted from the app JAR.

到目前为止，一切都很好.

So far, so good.

但是，我想修改行为，使图像文件的路径与从中复制的路径不同:

However, I want to modify the behaviour such that the path of the image file is different than what is being copied from:

目前:

com/izforge/izpack/panels/MyIzPanel.class
com/xyz/img/logo.png

我想要的:

com/izforge/izpack/panels/MyIzPanel.class
blah/img/logo.png

所以我需要复制文件，但使用 和 这样我就可以修改目录结构了.

So I need to copy the files, but use <zipfileset> and <jar> in such a way that I can modify the directory structure.

有没有办法做到这一点，除了解压缩整个内容复制文件然后再次压缩它?

Is there a way to do this, apart from unzipping the entire contents copying file and then zipping it back up again?

推荐答案

您可以使用 fullpath 属性:

<zipfileset src="${pwd}/dist/app.jar"
    includes="com/xyz/img/logo.png" fullpath="blah/img/logo.img"/>

如果您需要复制多个文件，您可能需要查看 prefix 属性，例如:

If you need to copy several files you may want to have a look at the prefix attribute, e.g.:

<zipfileset src="${pwd}/dist/app.jar"
    includes="**/*.png" prefix="blah/img"/>
