how to achieve Concurrency with groovy script used in freestyleproject

[Sivakumar Durairaj]

Hi All,


Can please help me on how to achieve concurrency using groovy script in 
Jenkins freestyleproject?.

I have tried to execute below script. But I am getting the following error 
"Caught: 
groovy.lang.MissingMethodException: No signature of method: main.parallel() 
is applicable for argument types: (java.util.LinkedHashMap) values: 
[[job1:main$_run_closure1$_closure2@776aec5c, 
job2:main$_run_closure1$_closure2@1d296da, ...]]

at main.run(main.groovy:23)" Script def jobsString = "job1,job2,job3"
ArrayList jobsList = jobsString.split('\\,')

def parallelJobs2Run = [:]
jobsList.each { job ->
    echo "Going to parallel for job ${job}"
    parallelJobs2Run["${job}"] = { ->
        echo "Calling job ${job}"
        jobResults=build job: "${pathJenkinsFolder}${job}",
        parameters: [
            string(name: 'param1', value: "${value1}"),
            string(name: 'param2', value: "${value2}")
        ],
        propagate: true,
        wait: true

        buildNumber = ${jobResults.number}
        echo "${job} Build number |${buildNumber}| result: 
|${jobResults.result}|"
        echo "See details on: |${jobResults.absoluteUrl}|"
    }
};
parallel parallelJobs2Run
