Curl request from command line and via Groovy script

问题:

I am facing an issue which i do not understand, I have written a simple groovy script that when called from the command line works as expected

#!/usr/bin/env groovy  def jsonParse(def json) {   new groovy.json.JsonSlurperClassic().parseText(json) }  def ticketNumbers = ["MYSTATS-2695", "MYSTATS-2694"]   ArrayList jiraLinks = new ArrayList();    for(int i =0; i 

so when i do groovy myscript.groovy

This will print out

[[MYSTATS-2695 ](https://jira.dev.org.co.uk/browse/MYSTATS-2695 ) - Jenkins build pipeline should ignore draft and pre-releases, [MYSTATS-2694 ](https://jira.dev.org.co.uk/browse/MYSTATS-2694 ) - Android Jenkins pipeline should populate the comscore SDK version automatically] 

So that is as expected.

What i then have is a groovy script which i call as part of a jenkins pipeline build

class Helpers {     def jsonParse(def json) {      new groovy.json.JsonSlurperClassic().parseText(json)    }    def createJiraLinks(def ticketNumbers) {      ArrayList jiraLinks = new ArrayList();     for(int i =0; i 

As part of my Jenkins build i have

def groovyMethod = load("${env.WORKSPACE}/groovy_scripts/release_pipeline.groovy") def jira = groovyMethod.createJiraLinks(ticketNumberCommits); echo "JIRA LINKAS ARE $jira" // $jira is always returned as empty string 

Am i misunderstanding anything here as i would have expected this to work? but it seems as if the curl request never gets anything back

Thanks

groovy String.execute() returns Process that could be still running (depends on system load and weather))

if you want to wait until process ended do like this:

def txt = "cmd /c dir c:\\".execute().with{     def output = new StringWriter()     def error = new StringWriter()     //wait for process ended and catch stderr and stdout      it.waitForProcessOutput(output, error)     //check there is no error     assert error.toString().size()==0: "$error"     //println it.exitValue() //we can do check with error code     //return stdout from closure      return output.toString() } 

for jenkins pipeline to avoid error java.io.NotSerializableException use the following code:

node {     def res = runAndWait("cmd /c dir c:\\")     echo res }  @NonCPS String runAndWait(Object cmd){     def proc = cmd.execute()     def output = new StringWriter()     def error = new StringWriter()     //wait for process ended and catch stderr and stdout      proc.waitForProcessOutput(output, error)     //check there is no error     assert error.toString().trim().size()==0: "$error"     //assert proc.exitValue()==0 //we can do check with error code     //return stdout from closure      return output.toString() }
