问题：
Android Studio：未解析的java和javax导入引用，但项目编译
穆英飙
我正试图在Android Studio项目中创建自己的注释处理器。
我已经在Android Studio中为此创建了另一个模块。
我能够编译这个项目。我不能只使用自动完成和其他东西。在这种情况下，IDE将所有引用视为未解析的引用错误
我如何解决这个问题？
什么是重要的
当我创建新的库模块“autoadapter进程”时，默认情况下，Android Studio在构建中使用此实现创建了它。此模块的渐变：
implementation "org.jetbrains.kotlin:kotlin-stdlib-jdk7:$kotlin_version"
为了能够编译项目，我将其替换为：
implementation "org.jetbrains.kotlin:kotlin-stdlib-jdk8:$kotlin_version"
下面是我的项目结构：
以下是我对autoadapter处理器模块的Gradle配置：
apply plugin: 'java-library'
apply plugin: 'kotlin'
dependencies {
implementation fileTree(dir: 'libs', include: ['*.jar'])
implementation project(':autoadapter-annotations')
implementation "org.jetbrains.kotlin:kotlin-stdlib-jdk8:$kotlin_version"
}
这https://stackoverflow.com/a/61180376/104891这个问题和我的不一样，因为它是智能化的。它不是特定于Android Studio的。

看起来，Android Studio缓存了为新的Android Studio版本导入的一些以前的设置。我做了很长一段时间，可能是从3.1版开始更新-
因此旧的JDK版本似乎被缓存在JDK中。桌子xml文件
你可以在你的Android Studio选项文件夹中找到这个文件（在我的情况下，它是用户/库/首选项/Android Studio4.0/选项）
你可以删除它，让它再次创建正确的版本（这对我有效，是我问题的解决方案：https://stackoverflow.com/a/38067170/5434346
或者你可以尝试修改它（我没有尝试过）：https://stackoverflow.com/a/41531367/5434346
奇怪的是，它没有包含任何JDK 1.7参考：
