我有一个使用jpackage (Java 14) 打包的桌面 Java 应用程序。

Windows 安装程序

我想知道如何修改/覆盖 jpackage wix默认值，以便在环境变量中捕获安装位置。

我尝试使用 WiX Cookbook 中描述的方法添加环境变量（到 jpackage 创建的默认 main.wxs）：https ://learning.oreilly.com/library/view/wix-cookbook/9781784393212/ch13s02.html

<Component Id="cmpEnvironmentVariable" 
           Guid="{313075B5-BF2C-4012-9A6E-2F4E2C461306}"  
           KeyPath="yes">
     
  <Environment Id="myEnvironmentVariable"   
               Name="MyVariable" 
               Value="some value" 
               Action="set" 
               System="yes" />
 
</Component>

我还尝试向 jpackage 创建的 overrides.wxi 文件添加一个环境变量，我不认为这是正确的做法。

这两种尝试都导致 jpackage 失败。

我还花时间浏览了 WIX 文档，但发现它相当难以理解。

因此，任何提示、建议或示例将不胜感激。
