Gradle项目同步在Android Studio 3.1中失败

Question

my gradle.build contains

buildscript {

repositories {
    google()
    jcenter()
}
dependencies {
    classpath 'com.android.tools.build:gradle:3.1.0'


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

allprojects {
repositories {
    google()
    jcenter()
}
}

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

and upon syncing project with gradle files is showing error as connection refused:connect . There is a problem with Apply script build.gradle Not able to resolve dependencies of classpath

Log file showing the below error

Answer 1

Try using invalidate caches and restart in File Menu. Most of the time it works when studio have a new update.

Answer 2

Goto "File > Project Structure > SDK Location" menu and Check "Use embedded JDK(recommended)". It may be your JDK version problem.
