How add dependencies into groovy script? - groovy

Question

I try to add HttpBuilder into groovy script, but can do it only manually (Alt+Ctrl+Shift+S add dependencie). But when I start script I have error in line of creating new httpbuilder instance java.lang.ClassNotFoundException: org.apache.http.client.HttpClient. I manualy add HttpClient, butClassNotFoundException: net.sf.json.JSONObject and so on. But when I add Ini library it works fine.
I also tried to use #Grab
main()
def main() {
#Grab(group='org.codehaus.groovy.modules.http-builder', module='http-builder', version='0.7' )
def http = new groovyx.net.http.HTTPBuilder('http://www.codehaus.org')
And have compilation error
Error:Groovyc: While compiling GroovyTests: java.lang.RuntimeException: Error grabbing Grapes -- [download failed: net.sf.json-lib#json-lib;2.3!json-lib.jar]
And net in def http = new groovyx.net.http.HTTPBuilder('http://www.codehaus.org') is red and Cannot resolve a symbol 'net' error
will be glad to any help

Since you have now installed the groovy executables as per the comments, the following code:
#Grab('org.codehaus.groovy.modules.http-builder:http-builder:0.7')
import groovyx.net.http.HTTPBuilder
def http = new HTTPBuilder('https://jsonplaceholder.typicode.com')
def res = http.get(path: '/users')
println "Number of users: ${res.size()}"
should now run and print:
─➤ groovy solution.groovy
Number of users: 10
─➤
(tested on Groovy Version: 2.5.8 JVM: 1.8.0_232 Vendor: AdoptOpenJDK OS: Linux)
One thing that might be disrupting the artifact resolution is if you have a custom grapeConfig.xml file. This file (if it exists) should be under <user home dir>/.groovy/grapeConfig.xml and the default text that groovy uses if no grapeConfig.xml file is present can be found here:
https://github.com/apache/groovy/blob/master/src/resources/groovy/grape/defaultGrapeConfig.xml
In addition, if you need to debug grapes downloads, you should try the following flags (again as mentioned in the comments):
─➤ groovy -Dgroovy.grape.report.downloads=true -Divy.message.logger.level=4 yourGroovyScript.groovy
which should print information on what grapes are actually doing when the resolution fails.
What does your groovy -v look like? i.e. what version of groovy and what jdk are you on?
