Failed to resolve: support-core-ui

问题:

This is all I have as my project's repositories:

repositories {     jcenter()     google()     maven { url "https://maven.google.com" } } 

This is all I have as my project's dependencies:

dependencies {     compile 'com.google.android.gms:play-services:12.0.1'     compile 'com.android.support:support-v13:27.1.1'      compile 'com.android.support:support-core-ui:27.1.1'     compile 'com.android.support:support-core-utils:27.1.1'      compile 'com.google.android.gms:play-services-appinvite:16.0.0'     compile 'com.google.firebase:firebase-core:16.0.0'      compile 'com.google.android.gms:play-services-gcm:15.0.1'     compile "com.android.support:support-core-utils:27.1.1"     compile files('libs/dagger-1.2.2.jar')     compile files('libs/javax.inject-1.jar')     compile files('libs/nineoldandroids-2.4.0.jar')     compile 'com.google.android.gms:play-services-ads:15.0.1'     compile 'com.android.support:multidex:1.0.1' }

I solved this issue by changing

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

into

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

in project level build.gradle file, i.e. first writing google().

This is the answer:

buildscript {     repositories {         google()         jcenter()     } }  allprojects {     repositories {         google()         maven { url "https://maven.google.com" }         jcenter()     }
