如何告诉ProGuard保持私有字段，而无需指定每个字段 [英] How to tell ProGuard to keep private fields without specifying each field

问题描述

这是我的类：

package com.tools.app.holiday;

public class Holiday {  

    private String name;

    private Calendar dateFrom = Calendar.getInstance();

    private Calendar dateTo = Calendar.getInstance();

    ...

我可以把我的ProGuard以下规则让这些私人领域的文件：

I can keep these private fields by putting the following in my ProGuard rules file:

-keepclassmembers class com.tools.app.holiday.Holiday {
    private java.lang.String name;    
    private java.util.Calendar dateFrom;
    private java.util.Calendar dateTo;
}

不过我倒是preFER不要有单独指定每个字段。我怎样才能做到这一点？

But I'd prefer not to have to specify each field individually. How can I do this?

P.S。我偷了其中的大部分来自 Proguard的保持classmembers 的，因为这个问题是接近我在问什么。

P.S. I stole most of this from Proguard keep classmembers because that question was close to what I'm asking.

推荐答案

根据 ProGuard的documenation 的通配符＆LT;场＆GT; 匹配任何领域。因此，它应该是这样的：

According to ProGuard documenation the wildcard <fields> matches any field. Thus it should be something like:

-keepclassmembers class com.tools.app.holiday.Holiday {
    private <fields>;    
}

如果你想在所有类preserve私有字段使用：

If you want to preserve private fields in all classes use:

-keepclassmembers class * {
    private <fields>;    
}
