Jenkins: trigger build when changes occur to one branch, but fire script in another branch

Question

I have a Jenkins Pipeline Job that triggers when changes are pushed to a Git repository:

pipelineJob('MyJob') {
    definition {
        cpsScm {
            scm {
                git {
                    remote {
                        url('[email protected]:myorg/myproject.git')
                        credentials('jenkins-bitbucket')
                    }
                    branch('develop')
                    branch('master')
                    branch('release/*')
                    branch('hotfix/*')
                }
            }
        }
    }
    properties {
        triggers{
            bitbucketTriggers {
                repositoryPushAction(false,false,'develop')
            }
        }
        disableConcurrentBuilds()
    }
}

When the job triggers, I want to run a groovy script located in a different Git repository. Is that possible?

Answer 1

Yes there are two solutions,

1. Shared Libraries - url
2. This approach is more customized. You can create you own Java library and export as customlib.jar file. Ensure Java classpath appends the customlib.jar file you created. Then you can access the code directly in your JenkinsFile like import customlib.classname.*

Good luck!
