Spring Groovy Dynamic Language fails compilation when using Ivy Grab

Script such as:

@Grab('org.apache.httpcomponents:fluent-hc:4.5.13')
import org.apache.http.client.fluent.Request

class GrabExample 

}

ivy is on the classpath.

Appears to be related to how the scripts are "detected":

Comment From: StephenOTT

It seems to work running in a typical gradle run. But does not run as a fat jar.

Comment From: snicoll

Would you be able to share a small sample. You mentioned ivy on the classpath, so it would be better for us to be able to reproduce with the same environment.
