I have followed all the instructions to set it up but when I run gradlew runClient I get that error. Also when I run it in eclipse a bunch of imports aren't resolved.

FAILURE: Build failed with an exception.

allprojects {
        repositories {
        mavenLocal()
            maven { 
                url 'https://libraries.minecraft.net/' 
        }

        maven { url 'https://files.minecraftforge.net/maven' }
        jcenter()
        //mavenCentral() //TODO: Update Gradle to use HTTPS by default
        maven {
            name 'maven_central'
            url 'https://repo.maven.apache.org/maven2/'
        }
    }
}

to the top of the build.gradle
