Failed To Resolve: Support-core-ui

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 depend

Solution 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().

Solution 2:

This is the answer:

buildscript {
    repositories {
        google()
        jcenter()
    }
}

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