[FIXED] How to run two Jenkins multi phase Jobs at the same time?

Issue

I have two groups of multi-phase jobs, parallel test 1 and parallel test 2; where I need to execute both the groups together at the same time.

Does multi job jenkins plugin has a hack for it? or any alternatives...

Note: I don't want all the 3 jobs in the same MultiJob Phase

Solution

Since you can't run those jobs in one multijob phase, as an alternative You could use Jenkins pipeline job (Pipeline docs). Parallel stages execution can be achieved by using declarative pipeline parallel block. A dummy example of how your MultiJob could be achieved with pipeline:

pipeline {
    agent any
    stages {
        stage('MultiJob like stage') {
            parallel {
                stage('Parallel Test') {
                    steps {
                        echo "Here trigger job: allure_behave. Triggered at time:"
                        sh(script: "date -u")
                        // build(job: "allure_behave")
                    }
                }
                stage('Parallel Test 2') {
                    steps {
                        echo "Here trigger job: allure_behave_new. Triggered at time:"
                        sh(script: "date -u")
                        // build(job: "allure_behave_new")
                        echo "Here trigger job: allure_behave_old. Triggered at time:"
                        sh(script: """date -u""")
                        // build(job: "allure_behave_old")
                    }
                }
            }
        }
    }
}

In this case, You have a Stage called MultiJob like stage which has substages Parallel Test and Parallel Test 2 just like in your MultiJob. The difference is that both of those sub stages are being executed in parallel.

To trigger other jobs from inside the pipeline job use build step:

build(job: "job-name")

Or if you need to run it with parameters then just add parameters build() option:

build(job: "${JOB_NAME}", parameters: [string(name: 'ENVNAME', value: 'EXAMPLE_STR_PARAM')])

[Pipeline] }

[Pipeline] }

Finished: SUCCESS

Is this alternative valid for your use case?
