My project was running fine till yesterday. I haven't upgraded my Android Studio. But when I am trying to build my project I am seeing the following error:

Could not find gradle-core.jar (com.android.tools.build:gradle-core:3.1.2)
Searched in he following locations:
    https://jcenter.bintray.com/com/android/tools/build/gradle-core/3.1.2/gradle-core-3.1.2.jar

  • It seems to be a temporary issue of the repository servers. Maybe you can try using Maven Central or the Google mirror as repositories as suggested in the linked duplicate. – Lukas Körfer May 28 '18 at 11:22

sort your repositories like this:

jcenter()
mavenCentral()
google()
