Jenkins Groovy script to set CredentialsId

jenkins-set-credis.groovy

import hudson.model.*
import hudson.maven.*
import hudson.tasks.*
import hudson.scm.*

def match_url = "http://svn.mycorp.com/svn/devops"

for(item in Hudson.instance.items) {
  hasClaim = false;
  if (item.scm instanceof SubversionSCM)
  {
      for(location in item.scm.locations) {
        
        if (location.remote.startsWith(match_url)) {
          println("\n@@@@@@@@@@@@@@@@@")
          println("\njob $item.name")
          println("\n@@@@@@@@@@@@@@@@@")
        
          println("\nlocation $location.remote")
          credid = location.credentialsId
         
          if (credid != null)
            println("\ncredid $credid")
         }
      }
  } 
}

Did you found a way to update the read-only credentialsId property?

import java.util.*
import hudson.model.*
import hudson.matrix.*
import hudson.tasks.*
import hudson.scm.*

def match_url = "http://svn.mycorp.com/svn/devops"

hudson.model.Hudson.instance.items.findAll{job -> job.isBuildable() && job instanceof SCMedItem}.each{
job ->

def scm = job.getScm()
if (scm instanceof hudson.scm.SubversionSCM) {

def locationToDelete = null
for (int i = 0; i < scm.locations.length; i++) {
  def location = scm.locations[i]
  if (location.remote.startsWith("match_url")) {
        println(job.name + " : " + location.credentialsId + " : " + location.remote + " : " + location.local)
            scm.locations[i]  = location.withCredentialsId("d9e7f567-0f02-4e4a-a305-f61114e4f2a7")
            println(job.name + " : " + scm.locations[i].credentialsId + " : " + scm.locations[i].remote + " : " + scm.locations[i].local)
  }
}

}
job.save()
}

@elhabibmed, your script works just fine. Thanks

There is a bug in this line :

if (location.remote.startsWith("match_url")) {

There is no $ before variable name. It should be :

if (location.remote.startsWith("$match_url")) {

Also, this check :

&& job instanceof SCMedItem

on Jenkins 1.580.1 LTS caused that only jobs created as "Multi-configuration project" were affected. After fixing bug with "$" and after removing above check from if, script works just fine and changes all jobs matching "$match_url".

Please post the code to set the 'credentials id' as I've been searching for quite sometime now. This code deals with fetching the 'credentials id' Thanks in advnace
