Android Studio 3 Beta 1のNullPointerException

Question

AndroidスタジオにCanary 9からBeta 1に更新しました。プロジェクトを開いたときにこのエラーが発生しました。

キャッシュを無効にして再起動しましたが、運が良かったです。

私のGradleファイル：

buildscript { 
    ext.kotlin_version = '1.1.3' 
    repositories { 
     google() 
     jcenter() 
     maven { url 'https://maven.fabric.io/public' } 
    } 
    dependencies { 
     classpath 'com.android.tools.build:gradle:3.0.0-beta1' 
     classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version" 
     classpath 'io.fabric.tools:gradle:1.+' 

     // NOTE: Do not place your application dependencies here; they belong 
     // in the individual module build.gradle files 
    } 
} 

allprojects { 
    repositories { 
     google() 
     jcenter() 
     mavenCentral() 
     maven { url "https://jitpack.io" } 
    } 
} 

task clean(type: Delete) { 
    delete rootProject.buildDir 
}
