Gradle 'ProjectName' project refresh failed - Error: Already seen Doctype

[MehdiBrandoMahdloo]

Hi guys!
Thank you for your amazing stuff!
I'm trying to open (tried also to import) the project to Android Studio 1.2.1.1 with Gradle 2.2, but what I got is this silly error!

Gradle 'ProjectName' project refresh failed
Error: Already seen Doctype

Thank you so much!

the problem might be your network.
i changed my vpn and it worked for me.

to solve this problem i use psiphon3 and local proxy ports setting :
http/https : 8088

and change gradle.properties file (project root directory) and add these options.
systemProp.https.proxyPort=8088
systemProp.http.proxyHost=127.0.0.1
systemProp.https.proxyHost=127.0.0.1
systemProp.http.proxyPort=8088

for me works fine.

i have the same problem, but i am sure that my network isn't the problem, because i can download android APIs using sdk manager through android studio, i also used your method mr r.anjirabi, nothing helped back.
