How do I import a class in gradle outside of build.gradle in a apply from: file

I am having a wired issue I am using gradle 1.9

I cannot seem to import a class from outside build.gradle

The following works

build.gradle

buildscript {
    repositories {
        mavenLocal()
    }
    dependencies {
        classpath(group: 'com.foo', name: 'gradle-local-eureka', version: '1.0-SNAPSHOT')
    }
}
  import com.foo.my.awesome.package.AwesomeService

The following errors out build.gradle

buildscript {
    repositories {
        mavenLocal()
    }
    dependencies {
        classpath(group: 'com.foo', name: 'gradle-local-eureka', version: '1.0-SNAPSHOT')
    }
}
  apply from: file('gradle/foo.gradle')

foo.gradle

import com.foo.my.awesome.package.AwesomeService
  // do stuff

I get an unable to resolve class error if I try to import a class outside of build.gradle, does anyone have any insight as to why that wouldn’t work?

Where exactly is ‘com.foo.my.awesome.package.AwesomeService’ defined?
