问题描述
我在将Android 4.1.2更新到4.2.2之后收到此错误信息，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)
查看生成错误时发现此错误
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
几乎没有与error: Cannot find setter for field. - size in java.util.ArrayList语言完全相似的其他错误消息
我不能发布完整的课程，但我相信这些是相关的部分。在此类中，ArrayList仅使用一次
@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UserDao_Impl.java时发现
final ArrayList<E> _tmpThing;
if (! (_cursor.isNull(_cursorIndexOfSize))) {
_tmpThing = new ArrayList();
_tmpThing.size = _cursor.getInt(_cursorIndexOfSize);
} else {
_tmpThing = null;
}
在_tmpThing.size = _cursor.getInt(_cursorIndexOfSize);上出现错误，其他开发人员的内部版本中没有此部分
我相信可能与@Embedded var thing: ArrayList<Thing>?
非常奇怪的是，另一位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，但我在彻底擦除我的机器和最小安装后收到这个错误，只是通过Toolbox安装了Android Studio。
我已尝试的内容
- 已将Gradle更新为6.7.1，并将插件更新为
com.android.tools.build:gradle:4.2.2，相同错误 - 为
thing: ArrayList<Thing>?创建类型转换器，相同错误 - 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收到运行时崩溃 - 将我的JDK从嵌入式更改为JDK 11，相同错误
- 添加
kapt.use.worker.api=false，相同错误

推荐答案
问题是内置于更新版本的Android Studio和我们当前的Gradle设置中的jdk，特别是这个挡路
android {
kotlinOptions {
jvmTarget = "1.8"
}
}
Android Studio附带的内置JDK冲突。一旦我将Android Studio指向Java1.8JDK，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。在我的前一台计算机上，我使用Homebrew安装了OpenJDK 1.8然后我转到File -> Project Structure -> SDK Location -> JDK Location，将JDK指向新安装的1.8，而不是内置的JDK。
对于SDK Man，路径为/Users/me/.sdkman/candidates/java/8.0.292.hs-adpt
