Error:Cause: unable to find valid certification path to requested target

Answer 1

For me this worked:

buildscript {
    repositories {
        maven { url "http://jcenter.bintray.com"}
        maven {
            url 'https://maven.google.com/'
            name 'Google'
        }
    }
...
}

allprojects {
    repositories {
        mavenCentral()
        jcenter{ url "http://jcenter.bintray.com/" }
        maven {
            url 'https://maven.google.com/'
            name 'Google'
        }
    }
}
