Jenkins Using checkout scm to clone repo from Github

Question

Overview:

• I am trying to checkout the github code in my multi-configuration jenkins pipeline:

   package checkout void call() { println "checkout stage..." node { deleteDir() checkout scm } }

• I am using JTE (Jenkins Template Engine)

ISSUE:

But jenkins complains error Step checkout from the library checkout does not have the method call(GitSCM) after building the pipeline. Please find the stacktrace below:

As I am new in groovy and Jenkins, I would appreciate it if you could share any genuine solution or idea.

Answer 1

I found my issues and will post it here to be used by newbies like me:

I needed to do following changes and rerun the jenkins build to fix the issue:

1. Move the node keyword to the template jenkinsfile in /templates/jenkinsfile

    node('<executer node>') { scm_checkout() }

2. Update the pipeline_config.groovy file in /templates/ directory:

    libraries { merge = true scm_checkout }

3. Update the library directory name to scm_checkout. the directory and file name should be different form checkout to avoid referring the checkout(scm) to the wrong lib.

4. The checkout lib should in libraries/scm_checkout/scm_checkout.groovy and the content is like below:

    void call() { println "checkout stage..." deleteDir() def checkout = checkout(scm) }
