Cannot find Build Tools revision 25.0.0 rc1

[Dmitriy Ogirenko]

I try to build project from google samples - about rich content keyboard.

In app level build gradle:

android {
    compileSdkVersion 25
    buildToolsVersion "25 rc1"
    defaultConfig {
        applicationId "com.example.android.android.sampleapp"
        minSdkVersion 16
        targetSdkVersion 25
        versionCode 1
        versionName "1.0"
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    }
   

and this - build tools "25 rc1" cannot build
