问题
I am trying to use DataBinding in my existing project. As per the documentation I added below lines in app module's build.gradle and compiled the project.
dataBinding {
enabled = true
}
I got the below error:
Could not resolve all dependencies for configuration ':app:devDebugCompileClasspath'.
Could not find com.android.databinding:baseLibrary:3.0.0-alpha3. Searched in the following locations: file:/C:/Users/incnayak/AppData/Local/Android/sdk/extras/m2repository/com/android/databinding/baseLibrary/3.0.0-alpha3/baseLibrary-3.0.0-alpha3.pom file:/C:/Users/incnayak/AppData/Local/Android/sdk/extras/m2repository/com/android/databinding/baseLibrary/3.0.0-alpha3/baseLibrary-3.0.0-alpha3.jar file:/C:/Users/incnayak/AppData/Local/Android/sdk/extras/google/m2repository/com/android/databinding/baseLibrary/3.0.0-alpha3/baseLibrary-3.0.0-alpha3.pom file:/C:/Users/incnayak/AppData/Local/Android/sdk/extras/google/m2repository/com/android/databinding/baseLibrary/3.0.0-alpha3/baseLibrary-3.0.0-alpha3.jar file:/C:/Users/incnayak/AppData/Local/Android/sdk/extras/android/m2repository/com/android/databinding/baseLibrary/3.0.0-alpha3/baseLibrary-3.0.0-alpha3.pom file:/C:/Users/incnayak/AppData/Local/Android/sdk/extras/android/m2repository/com/android/databinding/baseLibrary/3.0.0-alpha3/baseLibrary-3.0.0-alpha3.jar https://jcenter.bintray.com/com/android/databinding/baseLibrary/3.0.0-alpha3/baseLibrary-3.0.0-alpha3.pom https://jcenter.bintray.com/com/android/databinding/baseLibrary/3.0.0-alpha3/baseLibrary-3.0.0-alpha3.jar https://jitpack.io/com/android/databinding/baseLibrary/3.0.0-alpha3/baseLibrary-3.0.0-alpha3.pom https://jitpack.io/com/android/databinding/baseLibrary/3.0.0-alpha3/baseLibrary-3.0.0-alpha3.jar https://maven.fabric.io/public/com/android/databinding/baseLibrary/3.0.0-alpha3/baseLibrary-3.0.0-alpha3.pom https://maven.fabric.io/public/com/android/databinding/baseLibrary/3.0.0-alpha3/baseLibrary-3.0.0-alpha3.jar Required by: project :app Could not find com.android.databinding:baseLibrary:3.0.0-alpha3.

回答1:
Add these lines to your module-level build.gradle as dependencies; Android Studio 3.0 changed the way it pulls in libraries that you previously downloaded via the SDK manager - https://developer.android.com/studio/build/dependencies.html#google-maven
implementation 'com.android.databinding:library:1.3.1'
implementation 'com.android.databinding:adapters:1.3.1'
You may not need the second line, depending on how you use data binding.
Instead of implementation, you can also use the old compile. Using implementation will avoid build warnings going forward; it's a part of the new Gradle Java library plugin that the Android Gradle plugin uses by default now.
You will also need to add something like the following (typically in your module-level build.gradle) if you don't have it yet - this adds Google's new Maven repository for Android dependencies:
repositories {
maven {
url 'https://maven.google.com'
}
}
