Setting up IntelliJ with Scala and SBT - scala

Question

I am trying to setup intellij with scala and sbt for development. I have already installed scala and SBT plugins on the IDE. However, when I try to create a new scala and sbt project, the build.sbt file shows the following errors:
Cannot resolve symbol :=
Cannot resolve symbol name
Cannot resolve symbol version
Cannot resolve symbol scalaVersion
Here is my build.sbt file which was created by the IDE itself:
name := "setup"
version := "1.0"
scalaVersion := "2.12.2"
The following are the steps I followed for creating the project:
Step One: File -> New Project
Step Two: Choose Scala from the left hand side panel and choose SBT on the right hand side panel (i.e SBT-based Scala project) and click Next.
Step Three: Fill in the project details and click Finish. ( Scala version -> 2.12.2, SBT version -> 0.13.13)
IntelliJ version - IntelliJ IDEA 2017.1.3
Edit:
Whenever I am trying to create a new project, I get the following error :
Error:Error while importing SBT project:<br/>...<br/><pre> https://repo1.maven.org/maven2/org/fusesource/jansi/jansi/1.11/jansi-1.11.jar

the Log file has the following content:

So I think this is an issue with my proxy settings and I definitely need to use the proxy. Is there a way to solve this??
Any help would be appreciated. Thank you.
