Gradle 3.0 Alpha 2 throwing exception

[Jonas Hao]

When using gradle build tool 3.0.0-alpha2 in Android studio preview

dependencies {
       classpath 'com.android.tools.build:gradle:3.0.0-alpha2'
}

I got this error:

ERROR: 
...\app\build\intermediates\manifests\full\debug\AndroidManifest.xml:15 unknown element <library> found

Execution failed for task ':app:processDebugResources'.
> Failed to execute aapt

It seems that the library element in AndroidManifest.xml has problem in this gradle version.

<library
        android:name="@string/app_name"
        android:label="@string/app_name" />
