如何使用proguard混淆除公共方法名称和属性之外的所有内容？

Question

我正在构建一个android框架,我需要对jar进行混淆和缩小以将其发送给用户.

我正在使用android SDK中包含的proguard工具,我对输出jar有以下要求:

• 保留输入jar中包含的所有类,但对它们进行模糊处理.
• 不要混淆`AndroidManifest.xml中调用的类的类名
• 不要混淆所使用的类的类名和公共方法名/属性具有用户的接口,但是对其内容执行此操作.

为此,我使用以下配置:

-optimizationpasses 5
-dontusemixedcaseclassnames
-dontskipnonpubliclibraryclasses
-dontpreverify
-verbose

-keep, allowobfuscation class com.company.*
-keepclassmembers, allowobfuscation class * {
    *;
}


-keepnames class com.company.MyClass { *; }
-keepclassmembernames class com.company.MyClass {
    public <methods>;
    public <fields>;
    #!private *; also tried this but it didn't work
}

但是,即使内容被混淆,我的私有类名称和属性仍然具有相同的名称.我在通配符中遗漏了什么吗？

玩了一下之后,我发现以下内容正在发挥作用

-optimizationpasses 5
-dontusemixedcaseclassnames
-dontskipnonpubliclibraryclasses
-dontpreverify
-verbose

-keep, allowobfuscation class com.company.*
-keepclassmembers, allowobfuscation class * {
    *;
}

-keepnames class com.company.MyClass
-keepclassmembernames class com.company.MyClass {
    public <methods>;
    public <fields>;
    #!private *; also tried this but it didn't work
}

配置中的错误是选项{ *; }末尾的存在-keepnames.

我使用了以下课程:

package com.company;

public class MyClass {
  public static void main(String[] args) {
    int longVariableName = publicStaticMethod();
    String abcxyz = privateStaticMethod("abc", "xyz");
    System.out.println("longVariableName: " + longVariableName);
    System.out.println("abcxyz: " + abcxyz);
  }

  public static int publicStaticMethod() {
    return 9000;
  }

  private static String privateStaticMethod(String first, String second) {
    return first + second;
  }
}

反编译的结果类是这样的:

package com.company;

import java.io.PrintStream;

public class MyClass {
  public static void main(String[] paramArrayOfString) {
    paramArrayOfString = publicStaticMethod();
    String str = a("abc", "xyz");
    System.out.println("longVariableName: " + paramArrayOfString);
    System.out.println("abcxyz: " + str);
  }

  public static int publicStaticMethod() {
    return 9000;
  }

  private static String a(String paramString1, String paramString2) {
    return paramString1 + paramString2;
  }
}
