Android Studio : unresolved reference for java and javax imports, 但项目编译

标签 android android-studio kotlin gradle

我正在尝试在 Android Studio 项目中创建自己的注释处理器。
我在 Android Studio 中为此创建了另一个模块.
我能够编译该项目。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 Unresolved 引用错误

我该如何解决这个问题？
什么是重要的
当我默认创建新的库模块“autoadapter-process”时，Android Studio 在 build.gradle 中为这个模块创建了这个实现:

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"
下面是我在项目结构 (Android Studio) 中的 JDK 设置:

下面是我的项目结构:
enter image description here
这是我的自动适配器处理器模块的 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"
}
这个 https://stackoverflow.com/a/61180376/104891 问题与我的不同，因为它是 IntelliJ IDEA 特定的。它不是 Android Studio 特定的 .

最佳答案

看来，Android Studio 缓存了为新的 Android Studio 版本导入的一些先前设置。当我可能从版本 3.1 -> 3.2 -> 3.4 -> ... -> 4.0 更新时，我已经做了很长时间了
所以旧的JDK版本似乎缓存在里面jdk.table.xml 文件
只要找到您的 Android Studio 选项文件夹，您就可以在其中找到此文件(在我的情况下，它是 User/Library/Preferences/AndroidStudio4.0/options)
您可以删除它并使用正确的版本再次创建它(这对我有用并且是我的问题的解决方案:

或者你可以尝试修改它(我没试过):https://stackoverflow.com/a/41531367/5434346
奇怪的是它没有包含任何 JDK 1.7 引用:

无论如何，新文件看起来像这样，现在我没有遇到我的问题(由于正文限制，我无法直接在此处发布内容)
https://pastebin.com/EdDKpZAT
但是，当我尝试在我的项目中创建新模块时，Android Studio 仍然使用我认为错误的配置和 JDK7 设置来创建它:
apply plugin: 'java-library'
apply plugin: 'kotlin'

dependencies {
    implementation fileTree(dir: 'libs', include: ['*.jar'])
    implementation "org.jetbrains.kotlin:kotlin-stdlib-jdk7:$kotlin_version"
}

sourceCompatibility = "1.7"
targetCompatibility = "1.7"
但是在该模块中，我可以导入对 javax 的引用

关于Android Studio : unresolved reference for java and javax imports, 但项目编译，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/62485630/
