Issue with Groovy script
Hi all,
I'm trying to run a simple groovy script in ExecuteScript processor to make
a HTTP GET request (I understand their are processors get this but I'm just
exploring Groovy at the minute).
import groovyx.net.http.HTTPBuilder
> flowFile = session.get()
> def http = new HTTPBuilder('https://google.com')
> def html = http.get(path : '/search', query : [q:'waffles'])
> log.warn(html)
> session.transfer(flowFile, REL_SUCCESS)
Ive included the http-builder jar as a dependency but I'm getting the error:
[image: Inline images 1]
I'm not new to NiFi but new to using Groovy. I've tried import
org.apache.http.* but that doesn't help. I'm assuming that the missing
class library is a default library in Groovy?
Any help much appreciated,
Mike

Thanks both - I assumed if I included the root directory that would not
only pick up the http-builder.jar but also the dependencies. Including the
dependencies directory fixed the issue.
Much appreciated,
Mike

Mike,
To follow up on Andy's question, you will likely need more than just
the http-builder JAR, I don't believe it is shaded (aka "fat JAR"). I
have the "http-builder-0.7-all.zip" unzipped to a folder, and it has
the http-builder-0.7.jar at the root level, but then a "dependencies"
folder as well. If you have something similar, you will want to add
the JAR and the dependencies folder to the Module Directory property.
Regards,
Matt

Mike,
When you say you’ve “included the http-builder jar as a dependency” do you mean you provided the location of the directory containing that JAR as the Module Path in the ExecuteScript processor?
