【问题描述】：
我正在尝试采用 MVVM 结构创建一些类以在 repo 的帮助下使用 repo 类获取 local 数据，我还使用 DI 来简化流程
JDK版本：
java version "1.8.0_201"
Java(TM) SE Runtime Environment (build 1.8.0_201-b09)
Java HotSpot(TM) 64-Bit Server VM (build 25.201-b09, mixed mode)
我使用的 java 8 定义在：build.gradle
minSdkVersion 21
targetSdkVersion 28
compileOptions {
targetCompatibility JavaVersion.VERSION_1_8
sourceCompatibility JavaVersion.VERSION_1_8
}
kotlinOptions {
jvmTarget = JavaVersion.VERSION_1_8
}
编译时异常：

我无法找出错误是什么？我进行了很多搜索，但仍然没有找到相关的答案。这是 Android Studio 错误还是 kotlin 错误或 JDK 错误或 eny 代码相关错误
