使用ProGuard混淆时露出内部类 [英] Exposing inner classes when obfuscating with ProGuard

问题描述

我使用Ant任务混淆库使用ProGuard。

I'm obfuscating a library with ProGuard using the Ant task.

我保持特定的类名和它们的方法名称时，他们有一个特别的注释（@ApiAll），我请求该InnerClasses属性保持：

I'm keeping particular class names and their method names when they have a particular annotation (@ApiAll) and I'm requesting that the InnerClasses attribute be kept:

  <keepattribute name="InnerClasses" />
  <keep annotation="com.example.ApiAll"/>
  <keepclassmembers annotation="com.example.ApiAll">
     <constructor access="public protected"/>
     <field access="public  protected"/>
     <method access="public  protected"/>
     <constructor access="protected"/>
    </keepclassmembers>

如果我检查的映射输出文件，我可以看到有注解我的内部类，它的成员都保持自己的名字是非模糊的。然而，当我看到在生成jar文件我找不到类。

If I check the mapping output file I can see that my inner class that has the annotation and it's members are keeping their names unobfuscated. However when I look in the generated jar file I can't find the class.

我缺少的东西吗？为什么映射告诉我这就是维持这个类时，它不是？

Am I missing something? Why is the mapping telling me it's keeping this class when it's not?

推荐答案

您需要指定要使用正确的符号，以保持内部类。
在ProGuard的说法，这意味着 -keep类my.outer.Class $ MyInnerClass 。这里的关键是使用美元符号（ $ ）的内部和外部类之间的分隔符。

You need to specify that you want to keep the inner class using the proper notation. In the proguard parlance, that means -keep class my.outer.Class$MyInnerClass. The key here is using the dollar-sign ($) as the separator between inner and outer class.

要做到这一点，你还必须指定 -keepattributes InnerClasses ，以便名称 MyInnerClass 不得到模糊处理。这两个设置在一起应该让你的内部类可保持不变。

To do this, you also have to specify -keepattributes InnerClasses, so that the name MyInnerClass doesn't get obfuscated. These two settings together should allow your inner classes to be kept intact.
