Gradle Could not HEAD https://..pom > peer not authenticated

Change your repository syntax to one of the following

repositories {
    jcenter {
        url "http://jcenter.bintray.com/"
    }
}


repositories {
    maven  {
        url "http://repo1.maven.org/maven2"
    }
}

Current (2.1) gradle docs claims that

Warning: Be aware that the central Maven 2 repository is HTTP only 
and HTTPS is not supported. If you need a public HTTPS enabled 
central repository, you can use the JCenter public repository 
(see Section 51.6.3, “Maven JCenter repository”).

I think maven central went for https. If I use following syntax.

repositories {
    mavenCentral()
}

I get following error.

D:\tools\gradle-2.1-bin\bin\gradle.bat -q
