Proguard won't keep a class member's enums
提问by Jesse
I'm working on a library that is distributed as a java jar, and I'm running proguard on it in such a way as to only leave the required interfaces exposed. I have a configuration class with a bunch of member variables and some enum defines. My proguard script preserves the member variables fine, however, the enum definitions are being obfuscated. I've tried everything I can think of to force proguard to retain these internally defined and public enums, but I can't get it to work.
我正在开发一个作为 java jar 分发的库，并且我正在以这样的方式运行 proguard，以便只暴露所需的接口。我有一个包含一堆成员变量和一些枚举定义的配置类。我的 proguard 脚本很好地保留了成员变量，但是，枚举定义被混淆了。我已经尝试了所有我能想到的方法来强制 proguard 保留这些内部定义和公共枚举，但我无法让它工作。
Right now I'm using:
现在我正在使用：
-keep public class com.stuff.MyConfigObject {
public *;
}
-keepclassmembers enum * {
public static **[] values();
public static ** valueOf(java.lang.String);
}
If I try:
如果我尝试：
-keep public enum com.stuff.MyConfigObject.MyEnum
I get an ambiguous error: "Note: the configuration refers to the unknown class 'com.stuff.MyConfigObject.MyEnum'"
我收到一个模棱两可的错误：“注意：配置指的是未知类 'com.stuff.MyConfigObject.MyEnum'”
Thanks for the help!
谢谢您的帮助！

Try com.stuff.MyConfigObject$MyEnuminstead. The Proguard class specificationexpects $as the separator for inner classes.
试试吧com.stuff.MyConfigObject$MyEnum。Proguard类规范期望$作为内部类的分隔符。
Actually, for what you want maybe the best option is something like this:
实际上，对于您想要的，最好的选择可能是这样的：
-keep public enum com.stuff.MyConfigObject$** {
**[] $VALUES;
public *;
}
This will keep only the required members for all enums nested within MyConfigObject- the required members being the $VALUES[]array (see this questionfor an explanation) and any publicmembers of the enum. Any other members (e.g. private fields methods) will not be kept.
这将只保留所有enum嵌套在MyConfigObject其中的必需成员 - 必需成员是$VALUES[]数组（有关解释，请参阅此问题）和public枚举的任何成员。不会保留任何其他成员（例如私有字段方法）。
As noted by Jesse and myself in the comments - since you are processing a library, you must also add the -keepAttributesoption. From the reference guide:
正如 Jesse 和我自己在评论中指出的那样 - 由于您正在处理一个库，您还必须添加该-keepAttributes选项。从参考指南：
For example, you should at least keep the Exceptions, InnerClasses, and Signature attributes when processing a library.
例如，在处理库时，您至少应该保留 Exceptions、InnerClasses 和 Signature 属性。

to keep all internal enums try this:
要保留所有内部枚举，请尝试以下操作：
-keep class * {
public enum **;
}
it saves me from writing every of 123 enum in proguard config.
它使我免于在 proguard 配置中编写 123 个枚举中的每一个。
Also, don't forget -keepAttributesif you are processing a library
另外，不要忘记-keepAttributes您是否正在处理库
