What Is the Proper Project Configuration for the N Developer Preview?

The docs claim a build.gradle like this works:

android {
  compileSdkVersion 'android-N'
  buildToolsVersion 24.0.0
  ...

  defaultConfig {
     minSdkVersion 'N'
     targetSdkVersion 'N'
     ...
  }
  ...
}

That gives me failed to find Build Tools revision 24.0.0, when using 'com.android.tools.build:gradle:1.5.0' for the Android Plugin for Gradle and Gradle 2.5.

If I look in build-tools/ in my Android SDK installation, I see 24.0.0-preview, not 24.0.0. However, if I switch my build.gradle to use buildToolsVersion "24.0.0-preview", I get Invalid revision: 24.0.0-preview.

So, what combination of build.gradle values works to build a project to compile against the N Developer Preview SDK?
