Answer 2

If you use VPN | Proxy on your system then use your proxy info in the gradle.properties file in your project like the following lines of code:

# HTTP Proxy
systemProp.http.proxyHost={Host Address}
systemProp.http.proxyPort={Port Number}
systemProp.http.proxyUser={Proxy Username}
systemProp.http.proxyPassword={Proxy Password}
systemProp.http.nonProxyHosts={NonProxy Hosts Address} # like: 127.0.0.1,localhost

# HTTPS Proxy
systemProp.https.proxyHost={Host Address}
systemProp.https.proxyPort={Port Number}
systemProp.https.proxyUser={Proxy Username}
systemProp.https.proxyPassword={Proxy Password}
systemProp.https.nonProxyHosts={NonProxy Hosts Address} # like: 127.0.0.1,localhost

Now just replace {.....} in the above code with appropriate data

Just to share infomation, I got same problem and the solution was different.

In my case, proxy server was used and it causes the problem. I needed to configure https proxy settings, as discussed in gradle behind proxy in Android Studio 1.3.

Maybe this help

allprojects {
    repositories {

    }
}

Answer 5

Add:

repositories {
   mavenCentral()
}

to the build.gradle. Now you have repositories defined only in build script which resolves dependencies only for the buildscript itself not for the project.

Answer 6

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

// mavenCentral() }
