react-native run-android => Could not resolve all dependencies for configuration ':classpath'

I insert java_home in environment correctly and test it in cmd. I am connecting to the internet with the proxy and can download react-native packages. adb devices run correctly on cmd, but when running "react-native run-android" command I give below error:

Make sure you have an Android emulator running or a device connected and 
have
set up your Android development environment:
https://facebook.github.io/react-native/docs/getting-started.html

Even I add Google() to build.gradle in allprojects{} It doesn't work again. and still giving that error. By the way, I am using JDK version 9 and gradle version 2.3.3

Unfortunately, Jcenter blocks requests from Iran due to US sanctions. You can use Hotspot Shield to connect to Jcenter, other VPN's providers may not work correctly. and i suggest you to update your gradle by this changes:

1- change gradle version to classpath 'com.android.tools.build:gradle:3.1.1' in android/build.gradle

2- change distributionUrl from android/gradle/wrapper/gradle-wrapper.properties to distributionUrl=https\://services.gradle.org/distributions/gradle-4.4-all.zip

3- add repository to android/build.gradle like this: 

repositories {
        mavenLocal()
        google()
        jcenter()
        maven { url "https://jitpack.io" }
        maven { url 'https://maven.google.com' }
    }

4- start Hotspot Shield and build project.

I hope this may help you.
