Your project's build.gradle should have the content as below. All the Google specific dependencies are now hosted on their own Maven Repository.

If you still find it confusing, just create a new Project from scratch using Android Studio 3.0.1 and all the dependencies would be properly configured.

buildscript {

    repositories {
        google() // Speficically this entry
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.0.1'
    }
}

First of all, make sure to update your Android Studio. Second thing, make sure you import the Google maven repository into your project gradle file. Then, you should be able to install ConstraintLayout.

Here's the solution:

repositories {
maven {
    url 'https://maven.google.com'
}

} then add this line in dependencies:

compile 'com.android.support.constraint:constraint-layout:1.0.2' compile 'com.android.support.constraint:constraint-layout-solver:1.0.2'
