[Known Issue] Error: Failed to resolve: com.twitter.sdk.android:twitter:2.0.0 when syncing with Gradle

If you are upgrading a project to version 1.0.0 you may encounter the error Failed to resolve: com.twitter.sdk.android:twitter:2.0.0 when syncing your project with Gradle. Version 1.0.0 has added a new required configuration step. To resolve this issue you must add the Fabric repository to your repositories:

repositories {
    // ...
    maven { url 'https://maven.fabric.io/public' }
}

Adding this to readme will be better.

I had the same problem in 1.0.0 and solved it. I have an android app module with an android library module (authentication). The authentication module has dependency on firebaseUI. I received the error above and solved it by adding the repositories to both build.gradle files. Not sure why this works, but I hope it helps:

app/build.gradle:

android {

  repositories {
    maven { url 'https://maven.fabric.io/public' }
  }
...

authentication/build.gradle:

android {

  repositories {
    maven { url 'https://maven.fabric.io/public' }
  }
...
