Gradle couldn't find com.android.databinding:dataBinder:1.0-rc0

Question

This is an old question which is irrelevant today. See Android developer's instruction. Applying Databinding to your projects is a lot easier now than four years ago.

As I am going over Android Data binding Guide from https://developer.android.com/tools/data-binding/guide.html. I have made sure I am running Android Studio 1.3 (canary version).

Following the guidelines, I get this error:

Gradle sync failed: could not find com.android.databinding:library:1.0-rc0 

Has anyone else have the same problem? Thanks for your help.

App build.gradle

buildscript {     repositories {         jcenter()     }     dependencies {         classpath 'com.android.tools.build:gradle:1.3.0-beta1'         classpath "com.android.databinding:dataBinder:1.0-rc0"     } }  allprojects {     repositories {         jcenter()     } }

Answer 1

I had this problem and solved it by adding "jcenter" under allprojects.repositories in my top-level build.gradle (I had been using mavenCentral).

buildscript {     repositories {         jcenter()     }     dependencies {         classpath 'com.android.tools.build:gradle:1.3.0'         classpath 'com.android.databinding:dataBinder:1.0-rc1'     } }  allprojects {     repositories {         mavenCentral()         jcenter() // <=== *** Adding this fixed it ***     } } 

Answer 2

I got errors when I sync build.gradle files.

Error:Failed to resolve: com.android.databinding:library:1.0-rc0

Error:Failed to resolve: com.android.databinding:adapters:1.0-rc0

And I finally found the solution.

dependencies {      // instead of the below pathes...     //classpath "com.android.tools.build:gradle:1.3.0-beta2"     //classpath "com.android.databinding:dataBinder:1.0-rc0"      // I used the following classpathes.... It works!     classpath "com.android.tools.build:gradle:1.3.+"     classpath "com.android.databinding:dataBinder:1.+"  }
