我已经将kotlin-reflect库添加到了我的Android项目中，现在Proguard生成了数百行笔记，列出了所有具有名为OpenSSH_6.6.1, OpenSSL 1.0.1f 6 Jan 2014

的字段的类，其中当然包括每一个Kotlin { {1}}。
这只是Proguard输出的一小部分：
INSTANCE如您所见，它既包含我自己的object类，又包含Kotlin标准库中的许多类，并且还可以在任何其他库中找到这些字段（如果存在）。
答案 0 :(得分：1)
错误的第一行告诉我们这里出了什么问题，它发现无论Note: kotlin.reflect.jvm.internal.KClassImpl$Data$objectInstance$2 accesses a declared field 'INSTANCE' dynamically
Maybe this is program field 'co.zsmb.example.proguardkttest.MySingleton { co.zsmb.example.proguardkttest.MySingleton INSTANCE; }'
Maybe this is program field 'kotlin.UNINITIALIZED_VALUE { kotlin.UNINITIALIZED_VALUE INSTANCE; }'
Maybe this is program field 'kotlin.Unit { kotlin.Unit INSTANCE; }'
Maybe this is program field 'kotlin._Assertions { kotlin._Assertions INSTANCE; }'
Maybe this is program field 'kotlin.collections.EmptyIterator { kotlin.collections.EmptyIterator INSTANCE; }'
Maybe this is program field 'kotlin.collections.EmptyList { kotlin.collections.EmptyList INSTANCE; }'
Maybe this is program field 'kotlin.collections.EmptyMap { kotlin.collections.EmptyMap INSTANCE; }'
Maybe this is program field 'kotlin.collections.EmptySet { kotlin.collections.EmptySet INSTANCE; }'
Maybe this is program field 'kotlin.comparisons.NaturalOrderComparator { kotlin.comparisons.NaturalOrderComparator INSTANCE; }'
是什么，它都通过反射访问名为MySingleton的字段。 Proguard不能告诉您该代码访问哪个kotlin.reflect.jvm.internal.KClassImpl$Data$objectInstance$2字段，所以它会向我们警告每个带有该字段的类，以防万一。
如果我们查看source of KClassImpl，就会很快找到culprit：它包含一个名为INSTANCE的属性，该属性在某些情况下会调用Class#getDeclaredField方法，传入一个以值INSTANCE作为参数的常量。这就是Proguard正在检测的内容。
因此，除非您具有单例类，并且您正在通过其objectInstance访问其实例，如下所示：
"INSTANCE"您可以忽略将以下规则添加到KClass文件中的Proguard注释：
val instance = MySingleton::class.objectInstance
您也可以精确地以proguard-rules.pro结尾，但是库中的实现更改将来可能会更改该位置编号。这样，您就可以忽略关于-dontnote kotlin.reflect.jvm.internal.KClassImpl$Data$objectInstance**
属性及其实现的所有注释。
