Ihave had the same problem. Finally I fixed it ussing an external gradle instalation. To make it you need to configure File->Settings->Build,Execution and deployments->Gradle Check -> Use local gradle distribution Select gradle home instalation.

If you are using an corporative connection, you also have to configure gradle proxy properties configuring or creating file gradle.properties in folder "/Users/user/.gradle":

#http proxy setup
systemProp.http.proxyHost=url
systemProp.http.proxyPort=port
systemProp.http.nonProxyHosts=*.nonproxyrepos.com|localhost

#https proxy setup
systemProp.https.proxyHost=url
systemProp.https.proxyPort=port
systemProp.https.nonProxyHosts=*.nonproxyrepos.com|localhost

That's all!
