 git         


        

Answer 1

Yes, you can do that with the Pipeline script from SCM option in a pipeline job by specifying multiple repositories (click on Add Repository button), assuming you can watch the same branch for your 3 repositories, which seems to be your case.

With this configuration (and of course the Poll SCM option activated), a build will be triggered every time a change is made to one of your three repositories.

A few more hints about this solution:

1. You need a Jenkinsfile in each repository
2. If you commited on more than one project between two SCM polls the result will be unpredictable (either one of the two projects you just committed in could finally get built) so you should not depend on which project gets built.
3. To solve previous point and also avoid code duplication, you should probably just load a generic script from each of your Jenkinsfile, such as:

Jenkinsfile in abc/def/ghi:

node {
    // --- Load the generic pipeline ---
    checkout scm: [$class: 'GitSCM', branches: [[name: '*/master']], extensions: [], submoduleCfg: [], userRemoteConfigs: [[url: 'http://github/owner/pipeline-repo.git']]]
    load 'common-pipeline.groovy'
}()

common-pipeline.groovy script:

{ ->
    node() {
       git clone github.com/owner/abc.git
       git clone github.com/owner/def.git
       git clone github.com/owner/ghi.git            

       // Whatever you do with your 3 repos...
    }
}
