AndroidX. Could not determine artifacts for androidx.multidex:multidex:2.0.0 - maven

Question

I try to migrate a project to AndroidX.
After 3 minutes of migrating it finished with error:
Gradle import

UPDATE
I updated all libraries in dependencies. Then in project's build.gradle I added
maven { url "https://jitpack.io" }
maven { url "https://maven.google.com" }
to repositories in both branches. After compilation I got:

Answer 1

I added in build.gradle (project) these lines:
maven { url "https://jitpack.io" }
maven { url "https://maven.google.com" }
So, it looks like:
buildscript {
repositories {
google()
jcenter()
maven { url "https://jitpack.io" }
maven { url "https://maven.google.com" }
}
dependencies {
classpath 'com.android.tools.build:gradle:3.4.1'
classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:1.3.40"
// NOTE: Do not place your application dependencies here; they belong
// in the individual module build.gradle files
}
}
allprojects {
repositories {
google()
jcenter()
maven { url "https://jitpack.io" }
maven { url "https://maven.google.com" }
}
}
task clean(type: Delete) {
delete rootProject.buildDir
}
Then synced gradle file. It downloaded some libraries from Maven. After compiling I got another error. Then I pressed Sync Project with Gradle files again.
See also https://developer.android.com/jetpack/androidx/migrate to understand what library and styles becomes what in AndroidX.
Strange, but after compiling and removing
maven { url "https://jitpack.io" }
maven { url "https://maven.google.com" }
back from build.gradle, the application run again.
