尽管阅读了常见问题解答，但 ProGuard 失败并显示 "Warning: class [] unexpectedly contains class []"

Question

我需要缩小 Scala 库以便将其包含在小程序中，但我不断收到类似以下的错误：[Being$$anon.class] unexpectedly contains class [stayAway.Being$$anon]（目录中的每个 class 都出现类似的错误).

我查看了 ProGuard FAQ，它说这个错误意味着我的目录配置不正确。据我所知，它是。

我有 8 个 class 个文件；都是 stayAway 套餐的一部分。它的设置如下：

- stayAway
    - Being$$anon.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'

这是我第一次使用 ProGuard，所以我可能忽略了一些东西。如有任何帮助，我们将不胜感激。

Answer 1

看起来您的 class 文件需要位于名为 "stayAway" 的目录中以匹配包名称，但我认为该目录必须相对于输入目录。也就是说，我认为你的输入目录

C:\Users\Brendon\Desktop\stayAway

包含 class 个文件？但如果这是您的输入目录，则需要 class 文件位于

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 class 个文件放入

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