We have a task to read the particular string from current job console output and send in mail.

I tried the below code to achieve this. This is written in Pipeline flow jenkinsfile from git.

import java.*
import java.lang.*
import hudson.*
import hudson.model.*
import jenkins.model.Jenkins

node() {

def binding = getBinding()
def manager = binding.getVariable("manager")
def log = manager.build.logFile.text
echo "${log}"
}

Always getting the below error.

groovy.lang.MissingPropertyException: No such property: manager for class: groovy.lang.Binding at groovy.lang.Binding.getVariable(Binding.java:63)
at groovy.lang.Binding$getVariable.call(Unknown Source)
at org.codehaus.groovy.runtime.callsite.CallSiteArray.defaultCall(CallSiteArray.java:48)
at org.codehaus.groovy.runtime.callsite.AbstractCallSite.call(AbstractCallSite.java:113)
 
 Detailed error are attached.

Jenkins version 2.19.1
