I created a Jenkins folder which has multiple jobs in it. I've also defined some variables in the folder itself. How can I check if the folder has a variable defined? I tied

import jenkins.model.*

private def getBuildJob(final String folder) {
  def jobFolder = null
  for (f in Jenkins.instance.getAllItems(AbstractItem.class)) {
    if (f.fullName == folder) {
      jobFolder = f
      break
    }
  }
  return jobFolder
}

node("linux-ubuntu") {
    stage("test") {
        def folder = getBuildJob("MyFolderName")
        println folder.hasVariable("MY_VARIABLE")
    }
}

But I get

hudson.remoting.ProxyException: groovy.lang.MissingMethodException: No signature of method: com.cloudbees.hudson.plugins.folder.Folder.hasVariable() is applicable for argument types: (java.lang.String) values: [MY_VARIABLE]

If you are using the folder-properties plugin you can use the following script.

@NonCPS
def checkVar() {
  def folderName = "Folderycr" 
  def propToCheck = "YCRPROP"
  def folderItem = Jenkins.instance.getAllItems(com.cloudbees.hudson.plugins.folder.AbstractFolder.class).find{ (it.name == folderName) }

  println folderItem.getProperties().each { prop ->
    if(prop instanceof com.mig82.folders.properties.FolderProperties){
      prop.getProperties().each{
        if(it.key == propToCheck) {
          println "Prop is available. Vale is : " + it.value
        }
      }
    }
  }
}

node("linux-node") {
  stage("Run test") {
    checkVar()
  }
}
