http-builder RESTClient dependencies

[Leo Dopson]

Hi Jaimie,

I'm hoping you can help pointing me in the right direction, I'm receiving this class dependency in my logs :

2013-03-27 11:24:40,153 http-bio-8081-exec-1 ERROR [webwork.util.ValueStack] METHOD: "promotedLinks", exception:

java.lang.NoClassDefFoundError: groovy/lang/GroovyObject

while using:

-----------------------

import groovyx.net.http.RESTClient

import groovy.util.slurpersupport.GPathResult;

import static groovyx.net.http.ContentType.URLENC

def myRC = new RESTClient("http://localhost/")

------------------------

I'm using the http-builder-0-1.7-20130216.204411-3.jar to access the RESTClient class.

I noticed that this class it's in the jar:

../META-INF/lib/groovy-all-1.8.5-scriptrunner.jar

Should I install groovy-all-1.0-jsr-06.jar to resolve this dependency? Or should this be picked up by your groovyrunner jar?

I decided to try apache's implementation instead, this script is called from another script and should really pass the rest_data parameter (needs to be cleaned up).

-rw-r--r-- 1 root root 115669 Mar 27 14:08 httpclient-cache-4.2.3.jar

-rw-r--r-- 1 root root 223571 Mar 27 13:53 httpcore-4.2.2.jar

-rw-r--r-- 1 root root 433070 Mar 27 13:51 httpclient-4.2.3.jar

Here is the script that eventually worked.

It's a bit of a pain using httpbuilder, because, although it is excellent and easy to use, the maven dependencies include a load of xml stuff and httpcommons that conflicts with other libraries in use.

I spent a couple of days trying to wade through those dependencies which eventually led to conflicting calls. After that, it just wasn't worth the effort.
