尽管阅读了常见问题解答，ProGuard 仍因“警告：类 [*] 意外包含类 [*]”而失败

【中文标题】尽管阅读了常见问题解答，ProGuard 仍因“警告：类 [*] 意外包含类 [*]”而失败

【英文标题】：ProGuard fails with "Warning: class [*] unexpectedly contains class [*]", despite reading the FAQ

【发布时间】：2015-05-08 10:28:58

【问题描述】：

我需要缩小 Scala 库，以便将其包含在小程序中，但我不断收到如下错误：[Being$$anon$1.class] unexpectedly contains class [stayAway.Being$$anon$1]（目录中的每个类都有类似的错误）。

我查看了 ProGuard 常见问题解答，它说这个错误意味着我的目录配置不正确。不过据我所知，确实如此。

我有 8 个类文件；都是stayAway 套餐的一部分。 它的设置如下：

- stayAway
    - Being$$anon$1.class
    - Being$.class
    - Being.class
    - MainFrame.class
    - NPC$.class
    - NPC.class
    - Player$.class
    - Player.class

使用以下配置（由 ProGuard GUI 生成）：

-injars 'C:\Users\Brendon\Desktop\stayAway'
-outjars 'C:\Users\Brendon\Desktop\scalaLibraryShrunk.jar'

-libraryjars 'C:\Program Files (x86)\Java\jre1.8.0_40\lib\rt.jar'
-libraryjars 'C:\Users\Brendon\Desktop\scala-library.jar'

这是确切的错误消息：

这是我第一次使用 ProGuard，所以我可能会忽略一些东西。 如有任何帮助，我们将不胜感激。

【参考方案1】：

看起来你的类文件需要在一个名为“stayAway”的目录中以匹配包名，但我认为这个目录必须是相对于输入目录的。 也就是说，我认为你的输入目录

C:\Users\Brendon\Desktop\stayAway

包含类文件？但是如果这是你的输入目录，你需要类文件在

C:\Users\Brendon\Desktop\stayAway\stayAway

同样，您可以将输入目录设置为

C:\Users\Brendon\Desktop\input

并将类文件放入

C:\Users\Brendon\Desktop\input\stayAway

【讨论】：

所以我只需要将它嵌套在另一个目录中？我会试试看（我真的希望你是对的，否则我必须将整个小程序翻译成 Java：/）

你是对的；添加额外的文件夹修复它。不过，ProGuard 现在正在弄乱库，因为它不允许加载小程序（但这超出了这个问题的范围）。谢谢。

不客气。我认为你在 Java 中也会遇到同样的问题。 ProGuard 期望您的文件夹结构镜像包结构，使用输入目录作为根目录。在原始示例中，所有类文件都位于“根”包目录中（在文件系统中恰好名为“C:\Users\Brendon\Desktop\stayAway”）。
