Lar*_*kin 6 android kotlin android-room
我在将 Android 4.1.2 更新到 4.2.2 后收到此错误消息，但在将 Android Studio 更新到 4.1.2 以上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)
在查看构建错误时，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与该error: Cannot find setter for field. - size in java.util.ArrayList语言相似
我无法发布完整的课程，但我相信这些是相关的部分。在这个类中ArrayList只使用一次
* 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)
在检查 UserDao_Impl.java 时我发现
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
出现错误“_tmpThing.size = _cursor.getInt(_cursorIndexOfSize);其他开发人员在其构建中没有此部分”
我相信这可能与@Embedded var thing: ArrayList<Thing>?
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该项目，所以我相信这是我的机器，但在完全擦除我的机器后我收到此错误最小安装，只需通过 Toolbox 安装 Android Studio。
我尝试过的事情
com.android.tools.build:gradle:4.2.2，同样的错误thing: ArrayList<Thing>?，同样的错误thing: ArrayList<Thing>?为列表，Entities and POJOs must have a usable public constructor错误kapt "androidx.room:room-compiler:2.3.0"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kapt.use.worker.api=false，同样的错误相关梯度部分

问题在于较新版本的 Android Studio 中内置的 JDK 以及我们当前的 Gradle 设置，尤其是此块
android {
kotlinOptions {
jvmTarget = "1.8"
}
}
Android Studio 内置的 JDK 存在冲突。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进行编译。
在我当前的计算机上，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
然后我将File -> Project Structure -> SDK Location -> JDK LocationJDK 指向新安装的 1.8，而不是内置的 JDK。
对于 SDKMan 来说，路径是/Users/me/.sdkman/candidates/java/8.0.292.hs-adpt
