【问题描述】：
我在将 Android 4.1.2 更新到 4.2.2 后收到此错误消息，但在将我的 Android Studio 更新到 4.1.2 以上的任何版本后收到此错误
* What went wrong:
Execution failed for task ':core:kaptDebugKotlin'.
> A failure occurred while executing org.jetbrains.kotlin.gradle.internal.KaptExecution
> java.lang.reflect.InvocationTargetException (no error message)
查看构建错误时，我发现了这个错误
error: Cannot find setter for field. - size in java.util.ArrayList/Users/xxxxx/XXXXX.Core-Android/core/build/tmp/kapt3/stubs/debug/com/XXXXX/android/core/entities/user/User.java:91: warning: Primary key constraint on placeId is ignored when being merged into com.xxxx.android.core.entities.user.User
几乎没有其他与error: Cannot find setter for field. - size in java.util.ArrayList 语言相似的错误消息
我无法发布完整的课程，但我相信这些是相关部分。在这个类中 ArrayList 只使用一次
@Entity
data class User(
@PrimaryKey @JsonProperty("userId") var userId: Int = 0,
@JsonProperty("email") override var email: String?,
...
@JsonProperty("place") @Embedded var place: Place?,
@JsonProperty("thing") @Embedded var thing: ArrayList<Thing>? = ArrayList(),
...
) : UserType
检查我发现的 UserDao_Impl.java 时
final ArrayList<E> _tmpThing;
if (! (_cursor.isNull(_cursorIndexOfSize))) {
_tmpThing = new ArrayList();
_tmpThing.size = _cursor.getInt(_cursorIndexOfSize);
} else {
_tmpThing = null;
}
_tmpThing.size = _cursor.getInt(_cursorIndexOfSize); 出现错误，其他开发人员的构建中没有此部分
我相信它可能与@Embedded var thing: ArrayList<Thing>?有关
非常奇怪的是，另一个开发人员也将他们的 Android Studio 更新到了 4.2.2，并且能够很好地编译项目，所以我相信这是我的机器，但是在完全擦除之后我收到了这个错误我的机器和最小的安装，只是通过 Toolbox 安装的 Android Studio。
我尝试过的事情
- 将 Gradle 更新到 6.7.1 并将插件更新到
com.android.tools.build:gradle:4.2.2，同样的错误 - 为
thing: ArrayList<Thing>?创建类型转换器，同样的错误 - 将
thing: ArrayList<Thing>?更改为列表，Entities and POJOs must have a usable public constructor错误 - 将
kapt "androidx.room:room-compiler:2.3.0"更改为annotationProcessor "androidx.room:room-compiler:2.3.0"，编译并通过所有测试，但在调用任何数据库方法时我收到运行时崩溃 - 将我的 JDK 从嵌入式更改为 JDK 11，同样的错误
- 添加
kapt.use.worker.api=false，同样的错误

【问题讨论】：
-
没有
ArrayList<E>.setSize，也没有暴露的可赋值size字段，所以..developer.android.com/reference/java/util/ArrayList 那么，它是如何到达那里的呢？ :|
