jenkins - Jenkinsfile with two git repositories

Question

I'm using the Jenkins pipeline plugin with a Jenkinsfile.

In one repository, called vms.git, I have the Jenkinsfile and an application it builds.

I have another repository called deploy.git, which contains scripts I want to use to deploy the application in vms.git.

At the moment my Jenkinsfile just looks like this

node {
  stage 'build'
  checkout scm

and I am defining the vms.git repo in the job configuration.

So what I would like to do is check out both repositories, then use the Jenkinsfile in vms.git to define the rest of the build. I want to reuse the deploy.git scripts in other pipelines so I don't want to put a Jenkinsfile in there.

You can checkout multiple directories using checkout, but you have to specify directory where you want checkout this. You can generate snippets using jenkins (Snippet generator bellow script field). Choose checkout, next git repository and in Additional Behaviours choose: checkout into sub directory.

When you will have 2 repositories you can load script from repository you want usin load. Example:

node {
    // first repository
    checkout([$class: 'GitSCM', branches: [[name: '*/master']], doGenerateSubmoduleConfigurations: false, extensions: [[$class: 'RelativeTargetDirectory', relativeTargetDir: 'subdirectory1']], submoduleCfg: [], userRemoteConfigs: [[url: 'repo1.git']]])
    // second repository
    checkout([$class: 'GitSCM', branches: [[name: '*/master']], doGenerateSubmoduleConfigurations: false, extensions: [[$class: 'RelativeTargetDirectory', relativeTargetDir: 'subdirectory2']], submoduleCfg: [], userRemoteConfigs: [[url: 'repo2.git']]])
    // run first script
    load 'subdirectory1/Jenkinsfile'
    // run second script
    load 'subdirectory2/Jenkinsfile'
}
