Question

在将Proguard与Kotlin反射一起使用时，我在运行时遇到问题。基本上，当我打电话给KClass.declaredMemberProperties时，我得到：

Incomplete hierarchy for class FieldBoundObject, unresolved classes [com.example.test.classes.DisposableObject]
kotlin.reflect.jvm.internal.components.RuntimeErrorReporter.reportIncompleteHierarchy

这是相关的堆栈跟踪：

这是Fieldbinder.kt中的相关呼叫：

class FieldBinder(receiver: Any) {

    private fun bindFields(receiver: Any, classToCheck: Class<*>) {
        for (property in classToCheck.kotlin.declaredMemberProperties) {
            //...
        }
    }

    // ...
}

这是“缺失”类DisposableObject

的签名

package com.example.test.classes

open class DisposableObject : ScopeProvider, Dispose {

    //...
}

我认为这与名称混淆有关。我尝试在实际的类本身上使用@Keep，并在Proguard文件中的类本身上使用-keep class。但是，解决此问题的方法是将名称保留在Proguard中：

-dontobfuscate

或

-keepnames class com.example.test.classes.DisposableObject

名称混淆和Kotlin反射是否存在问题？我在Java反射方面没有相同的问题。还是有解决此问题的更好方法？谢谢！

使用Proguard进行Kotlin反射-类的等级不完整
