If you are using an http proxy server, revise the following proxy settings in "gradle.properties" file in your project's root folder. If not using proxy server, just delete those entries.
systemProp.http.proxyPort=8080
systemProp.http.proxyUser=UserName
systemProp.http.proxyPassword=Passw0rd
systemProp.https.proxyPassword=Passw0rd
systemProp.https.proxyHost=proxy.abc.com
systemProp.http.proxyHost=proxy.abc.com
systemProp.https.proxyPort=8080
systemProp.https.proxyUser=UserName
