How to load .groovy file relative to remote jenkinsfile?

[cdleonard]

The standard way to load a .groovy file next to the Jenkinsfile is like this:

node('node') {
 stage('load') {
    code = load 'common.groovy'
  }
}

This tries to load a .groovy file relative to the project source code which is different when using the remote-file-plugin. One way would be to find the path where the remote jenkinsfile repository is checked out (some ...@script) path but I can't seem to figure this out.

The RJPP_JENKINSFILE variable seems almost useful but it's a relative path.

I know that I could use a separate "jenkins library" but having shared .groovy code inside a repo with centralized Jenkinsfile seems like it should work.

Best solution I found is

void checkoutRemoteJenkinsSource(String path='remote-jenkins') {
  checkout scmGit(
    branches: [[name: env.RJPP_BRANCH]],
    extensions: [[
      $class: 'RelativeTargetDirectory',
      relativeTargetDir: path,
    ]],
    userRemoteConfigs: [[
      credentialsId: 'jenkins@gitea-token',
      url: env.RJPP_SCM_URL
    ]]
  )
}

But that still requires a secondary checkout
