The documentation for for the groovy http-builder module used to live here-ish: http://repository.codehaus.org/org/codehaus/groovy/modules/http-builder/http-builder
After codehaus shut down did http-builder and HttpClient get moved / did apache start maintaining them? I'm wondering if there's newer-than-2014 version anywhere and where I could find up to date documentation? Google is not being helpful so clearly I'm searching for the wrong things.
The classic HttpBuilder is located here
https://github.com/jgritman/httpbuilder/wiki
you could grab it from maven repository using following annotation in groovy code:
@Grab(group='org.codehaus.groovy.modules.http-builder', module='http-builder', version='0.7.1')
import groovyx.net.http.HTTPBuilder
...
There is also a newer fork HttpBuilder-NG referenced in the documentation above
