Groovy script stuck on "Resolving dependency"

Question

I'm trying to run a simple groovy script for HTTP requests.

Using this dependecy:

@Grab(group='org.codehaus.groovy.modules.http-builder', module='http-builder', version='0.7.1')

Running from command line with this:

groovy -Dgroovy.grape.report.downloads=true script.groovy

I get this output:

Resolving dependency: org.codehaus.groovy.modules.http-builder#http-builder;0.7.1 {default=[default]}

And nothing else.

Groovy version:

Groovy Version: 2.3.6 JVM: 1.7.0_80 Vendor: Oracle Corporation OS: Linux
