我将项目迁移到AndroidX，在构建项目时遇到了这些错误：
[TAG] Failed to resolve variable '${project.groupId}'
[TAG] Failed to resolve variable '${project.version}'
[TAG] Failed to resolve variable '${project.groupId}'
[TAG] Failed to resolve variable '${project.version}'
[TAG] Failed to resolve variable '${project.groupId}'
[TAG] Failed to resolve variable '${project.version}'
我已经尝试了几种可能的解决方
enableJetifier设为false--refresh-dependencies添加到编译器设置这是我的项目gradle文件：
buildscript {
repositories {
jcenter()
maven {
url 'https://maven.google.com/'
name 'Google'
}
google()
maven {
url 'https://maven.fabric.io/public'
}

allprojects {

maven {

maven {

我运行gradlew assembleDebug --stacktrace --debug --info，这里有更多信息：
...

Caused by: java.lang.RuntimeException: Failed to transform 'C:\Users\me\.gradle\caches\modules-2\files-2.1\com.google.dagger\dagger-compiler\2.2\e411f732e5cd9697cdb291f6073b0d6ee2352023\dagger-compiler-2.2.jar' using Jetifier. Reason: The type does not support '.' as package separator! Received 'java.lang.Object;Ljava.lang.Class'.. (Run with --stacktrace for more details.) To disable Jetifier, set android.enableJetifier=false in your gradle.properties file.
因此看起来更喜欢和匕首是原因，但是对于迁移到AndroidX是必要的，并且我不想删除匕首。
如果我设置android.enableJetifier=false我有超过50个关于DataBinding的问题。

迁移到androidx后，Android Studio无法解析dagger-android和dagger-android-support类，如DaggerAppCompatActivity。 Issue link
我一直都有相同的问题，只需在Gradle和Sync Again中添加一些内容，问题就解决了，我认为这是来自Android Studio的错误
还有一个原因是Jetifier试图让图书馆满足于它所没有的假设。从Android gradle插件3.3.0-rc01和3.4.0-alpha04开始，有一种解决方法可以通过将指定库添加到gradle.properties的逗号分隔列表来禁用指定库：
android.jetifier.blacklist=byte-buddy,guava
解决方案是here
我通过将build.gradle（Module）中的变量更改为其版本来解决此错误，例如我更改了
implementation "androidx.room:room-rxjava2:$version"
至
implementation "androidx.room:room-rxjava2:2.1.0-alpha03"
并解决了:)
我使用的是Androidx，但是在升级Android Studio之前一切都运行良好。
我所做的就是File - Invalidate Caches/Restart。
<provider
android:name="android.support.v4.content.FileProvider"
android:authorities="@string/authorities"
android:exported="false"
android:grantUriPermissions="true"
>
<meta-data
android:name="android.support.FILE_PROVIDER_PATHS"
android:resource="@xml/filepaths" />
</provider>
当我遇到这个问题时，我通过删除.gradle /下的所有文件来解决。然后我又打开了android studio并再次构建。它得到了解决。
