Android Studio:未解析的Java和Javax导入参考，但项目已编译 [英] Android Studio: unresolved reference for java and javax imports, but project compiles
本文介绍了Android Studio:未解析的Java和Javax导入参考，但项目已编译的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我正在尝试在Android Studio项目中创建自己的注释处理器.
I am trying to create my own Annotation processor in Android Studio project.
我已经在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功能和其他功能.在这种情况下，IDE会将所有引用视为未解决的引用错误
I am able to compile the project. I can't just use autocomplete and other stuff. IDE treat all the references as unresolved references error in that case
如何解决此问题?
重要事项
当我创建新的库模块"autoadapter-process"时，默认情况下，Android Studio使用以下实现在build.gradle中为此模块创建了它:
When I created new libary module "autoadapter-process" by default Android Studio created it with this implementation in build.gradle for this module:
implementation "org.jetbrains.kotlin:kotlin-stdlib-jdk7:$kotlin_version"
为了能够编译该项目，我将其替换为:
To be able to compile the project I replaced it to:
implementation "org.jetbrains.kotlin:kotlin-stdlib-jdk8:$kotlin_version"
以下是我在项目结构(Android Studio)中的JDK设置:
Below is my JDK setup in Project Structure (Android Studio):
下面是我的项目结构:
这是我对自动适配器处理器模块的Gradle配置:
And here is my Gradle configuration for autoadapter-processor module:
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"
}
此 https://stackoverflow.com/a/61180376/104891 问题不是我的类似问题，因为它是IntelliJ IDEA规范.它不是特定于Android Studio的.
推荐答案
似乎，Android Studio缓存了一些为新的Android Studio版本导入的先前设置.当我可能从3.1版进行更新时，我已经做了很长时间了. 3.2-> 3.4-> ...-> 4.0
It seems, that Android Studio cache some previous settings imported for the new Android Studio version. I was doing it pretty much for long time when updating probably from versions 3.1 -> 3.2 -> 3.4 -> ... -> 4.0
因此，旧的JDK版本似乎已缓存在 jdk.table.xml 文件中
So the old JDK version seemed to be cached inside jdk.table.xml file
只要找到Android Studio选项文件夹(在我的情况下是User/Library/Preferences/AndroidStudio4.0/options)，您都可以在此文件中找到该文件
You can find this file inside whenever your Android Studio options folder is located (in my case it was User/Library/Preferences/AndroidStudio4.0/options)
您可以删除它，然后使用适当的版本重新创建它(对我有用，是解决我的问题的方法: https://stackoverflow.com/a/38067170/5434346
You can either delete it and let it be created again with proper versions (which worked for me and is the solution for my problem: https://stackoverflow.com/a/38067170/5434346
或者您可以尝试对其进行修改(我没有尝试过): https://stackoverflow.com/a/41531367/5434346
Or you can try to modify it (I did not tried that): https://stackoverflow.com/a/41531367/5434346
奇怪的是它没有包含任何JDK 1.7参考:
What is strange it did not contained any JDK 1.7 references:

但是，当我尝试在项目内部创建新模块时，Android Studio仍然使用错误的配置和JDK7设置来创建它:
However, when i try to create new module inside my project Android Studio still create the it with I think wrong configuration and JDK7 setup:
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，我可以将对javax的引用导入
But inside that module I am able to import my references to javax
