带有proguard的Kotlin AAR库:如何仅保留类和方法名称? [英] Kotlin AAR library w/ proguard: How to keep ONLY class and method names?

问题描述

我正在用Kotlin构建一个android库(aar文件).我需要以一种使第三方用户看到类和方法名称的方式来混淆代码，他必须能够使用它们(它们是pubilc)，但是我需要隐藏/混淆代码本身. 我尝试将此文件用于myLibrary \ proguard-rules.pro文件: https://github.com/mohitrajput987/android-实用程序/blob/master/preference/proguard-rules.pro

I am building an android library (aar file) with Kotlin. I need to obfuscate the code in a way that the 3rd party user will see the class and method names, he must be able to use them (they are pubilc), but I need to hide/obfuscate the code itself. I tried using this file for the myLibrary\proguard-rules.pro file: https://github.com/mohitrajput987/android-utility/blob/master/preference/proguard-rules.pro

但是每个类，方法和var都会更改，除了其中既包含Kotlin类别又包含Java类的目录之外，文件和目录名称均保持不变.

but every class, method and var is changed, except for a directory that has both a Kotlin and a Java class in it, both files and directory name remained the same.

如果这是我要寻找的东西，那么Kotlin必须更改什么?

If this is what I am looking for, what must be changed for Kotlin?

也许其他地方有问题吗?

Perhaps something else is wrong?

buildTypes {
    release {
        minifyEnabled true
        proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
    }
}

}

推荐答案

万一其他人对此问题感到困惑，在大多数情况下(当不尝试混淆本机方法时)，这应该可以解决问题:

In case anyone else struggle with this issue, this should do the trick in most cases (when not trying to obfuscate native methods):

-keepclasseswithmembernames class * {
     public <methods>; 
}
