We annotated a method of an external library as @NotNull using external annotation, so we won't need to use "!!" on the returned value. When compiling with intelliJ this works fine, however when running gradle build we get:

warning:Annotations path entry points to a non-existent location:  
Only safe (?.) or non-null asserted (!!.) calls are allowed on a nullable receiver of type …?  
Execution failed for task ‘:compileKotlin’.

it looks like grade isn’t aware of the external annotations file?

10x,

Hi, If you want to add annotations for some of your libraries, you should add the following line to your build.gradle file:

> kotlinOptions.annotations = file('\<path to annotations\>')

Annotations for JDK should be configured automatically. Here is a [link](http://kotlinlang.org/docs/reference/using-gradle.html#using-external-annotations)

Is this still valid? I cannot find it. Has it been moved?
