Whenever I do anything with gradle I get an exception error

Hey guys, I keep getting this error whenever I do anything with gradle. It started when I tried to build a mod and the build failed. Now, I'm trying to build a new workspace and I keep getting the same exact ever. I'm not sure what to do.

 

This is what I keep getting:

 

FAILURE: Build failed with an exception.

 

* What went wrong:

A problem occurred configuring root project 'NightmareCreatures'.

> Could not resolve all dependencies for configuration ':classpath'.

  > Could not resolve net.minecraftforge.gradle:ForgeGradle:1.2-SNAPSHOT.

    Required by:

        :NightmareCreatures:unspecified

      > Unable to load Maven meta-data from http://files.minecraftforge.net/maven/net/minecraftforge/gradle/ForgeGradle/1.2-SNAPSHOT/maven-metadata.xml.

        > Could not GET 'http://files.minecraftforge.net/maven/net/minecraftforge/gradle/ForgeGradle/1.2-SNAPSHOT/maven-metadata.xml'. Received status code 403 from server: Forbidden

 

* Try:

Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output.

 

BUILD FAILED

Thank's man, it really did turn out to be a server problem!
