error: Cannot find setter for field. - size in java.util.ArrayList - Embedded ArrayList in Room unable to compile

Question

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 更新到高于 4.1.2[=26 的任何版本后收到此错误消息=]

* 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

几乎没有其他错误消息都与 error: Cannot find setter for field. - size in java.util.ArrayList 语言相似

我无法 post 完整 class 但我相信这些是相关部分。在这个class ArrayList只用了一次

@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 UserDao_Impl.java 时我发现

final ArrayList<E> _tmpThing;
            if (! (_cursor.isNull(_cursorIndexOfSize))) {
              _tmpThing = new ArrayList();
              _tmpThing.size = _cursor.getInt(_cursorIndexOfSize);
            }  else  {
              _tmpThing = null;
            }

_tmpThing.size = _cursor.getInt(_cursorIndexOfSize); 出现错误其他开发者的构建中没有此部分

我认为这可能与 @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 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，但我收到了这个完全擦除我的机器并进行最小安装后出现错误，只需 Android 通过工具箱安装 Studio。

我尝试过的东西

已将 Gradle 更新为 6.7.1 并将插件更新为 com.android.tools.build:gradle:4.2.2，同样的错误
正在为 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

Answer 1

我遇到了类似的问题，只需从位于实体中的 ArrayList 属性中删除注释“@Embedded”即可。

Answer 2

问题是 JDK 内置于更新版本的 Android Studio 和我们当前的 Gradle 设置中，尤其是这个块

android {
    kotlinOptions {
        jvmTarget = "1.8"
    }
}

Android Studio 包含的内置 JDK 冲突。一旦我将 Android Studio 指向 Java 1.8 JDK，它就会在我的机器和新机器上编译。

在我当前的机器上，我使用 SDKMan 安装了 AdoptOpenJDK 8.0.292.hs。在我之前的机器上，我使用 Homebrew

安装了 OpenJDK 1.8

然后我转到 File -> Project Structure -> SDK Location -> JDK Location 并将 JDK 指向新安装的 1.8，而不是内置 JDK。

对于 SDKMan，路径是 /Users/me/.sdkman/candidates/java/8.0.292.hs-adpt
