Can you provide an example of what you are doing?

Thanks for the quick response!

I'm trying to use RESTClient. Example:

def http = new RESTClient('https://api.hipchat.com')
http.post(
path : '/v1/rooms/message',
body : postBody,
query : query,
requestContentType : URLENC )

The way I'm able to use it with Execute System Groovy Script is I execute a gradle build to pull the dependencies and Then I add: '${WORKSPACE}/libs/http-builder-0.7.2.jar:${WORKSPACE}/libs/xml-resolver-1.2.jar' to the System groovy script classpath. I can then import both: 'import groovyx.net.http.ContentType,
import groovyx.net.http.RESTClient'.

When I try the same thing in the E-Mail EXT PreSend script (Add the 2 jars to the classpath, add the imports) I get unable to resolve. I tried using @Grab but I got an IVY error (I believe that's a whole other issue).

Thanks for all the help!

Can you post the error you are getting?

org.codehaus.groovy.control.MultipleCompilationErrorsException: startup failed:
Script1.groovy: 2: unable to resolve class groovyx.net.http.RESTClient
@ line 2, column 1.
import groovyx.net.http.RESTClient
^

Script1.groovy: 1: unable to resolve class groovyx.net.http.ContentType
@ line 1, column 1.
import groovyx.net.http.ContentType

Are you adding the classpath at the project level, or in the local config?

I think the problem is that the classpath is never resolved for environment variables, so ${WORKSPACE} isn't getting replaced with the path to the workspace. I'll play around with this some more and verify that is what is happening.

Thank you. I haven't tried the full path either. I'll give it a go also, but it seems the most logical explanation.
