How to start a job from another job in a declarative pipeline?

[Idan Adar]

Hi,

Lets assume there are two job:

1. a job for a micro-service repository

2. a job for end-to-end tests

I'd like, in specific cases, to start the end-to-end tests job from the micro-service job.

For example, after introducing a change that even though passed unit testing and integration testing, it needs further testing, available in the end-to-end tests job.

I'd like for the developers to make a commit with a specific phrase, e.g. "[e2e]" and to use it as follows (just pseudo code for now).

pipeline {
    ...
    ...
    stages {
        ...
    }    


    post {
        success {
            if (BRANCH_NAME == "develop") {
                result = sh (script: "git log -1 | grep '.*\\[e2e\\].*'", returnStatus: true)
                if (result == 0) {
                    // start the d2d job
                }
            }
        }
    ...
    ...
    }
}

This is how I do this, should be easy enough -

pipeline {

stages {

        stage ('xxx') {

            steps {

...

...

                build job: '<job-name-here>', parameters: [

                    string(name: 'PARAM1', value: "xxx"),

                    string(name: 'PARAM2, value: "yyy")

                ]

            }

      }

}

Yep, found "build" as well. I thought maybe it's done differently in declarative pipelines...

Ended up with the following, however despite this, it did not start.

post {
   // Run end-to-end tests, if requested
   success {
      script {

         if (BRANCH_NAME == "develop") {
            result = sh (script: "git log -1 | grep '.*\\[e2e\\].*'", returnStatus: true)
            if (result == 0) {

               build job: '****', wait: false
            }
         }
      }
   }
}

The following was logged: 

+ git log -1
+ grep '.*\[e2e\].*'
    Run tests [e2e]
[Pipeline] build (Building ****)
Scheduling item: ****

But when visiting that job's Stages View, there is no build running.

Could this be because the end-to-end job is also scheduled to run at specific time? Its Jenksinfile has the following specified: 

pipeline {
    triggers {

        cron ('0 12,16,20 * * 1-4,7')
    }
    ...

(run everyday except Friday and Saturday, at 12:00, 16:00 and 20:00).

I should mention that both jobs are multi-branch jobs...

should the job name also somehow incorporate the branch name? i.e. "develop"

[Idan Adar]

That was it... just had to specify the branch. d'oh.

 build job: '****/master', wait: false
