My system suddenly went off and I switched it on and I got Error:Failed to resolve: android.arch.core:common:1.1.0 error in my android studio. I have tried clean and rebuild project but it did not work. I have researched on the internet but none could solve my problem.
build. gradle(project)
// Top-level build file where you can add configuration options common to all sub-projects/modules.
buildscript {
repositories {
    jcenter()
}
dependencies {
    classpath 'com.android.tools.build:gradle:2.2.0'
    // NOTE: Do not place your application dependencies here; they belong
    // in the individual module build.gradle files
}
}

I don't know what could be the cause of the problem.
