In Android Studio, Error in Gradle: HttpRequestException: Could not HEAD '..kxml2-2.3.0.jar'

Question

I am new to android development, am using Android studio.

getting the following error after I've just created my new project.

have checked proxy settings using the Settings --> HTTP proxy --> check connection and I am able to connect properly. Since that is ruled out. I took a look at the idea.log

I am getting an exception which seems very much like its not able to download the jar: 'https://jcenter.bintray.com/kxml2/kxml2/2.3.0/kxml2-2.3.0.jar'

Caused by: org.gradle.internal.resource.transport.http.HttpRequestException: Could not HEAD 'https://jcenter.bintray.com/kxml2/kxml2/2.3.0/kxml2-2.3.0.jar'.
at org.gradle.internal.resource.transport.http.HttpClientHelper.performRequest(HttpClientHelper.java:80)
at org.gradle.internal.resource.transport.http.HttpClientHelper.performRawHead(HttpClientHelper.java:58)
at org.gradle.internal.resource.transport.http.HttpClientHelper.performHead(HttpClientHelper.java:62)

when I launch the url it says the jar is not available: shows a JSON with a 404 error message.

Is there any way that I can change the URL to one that works or just download it from other sources and skip this step altogether?

Please help me out.
