Trouble using shared pipeline libraries

[Ramanathan Muthaiah]

Am running Jenkins v2.3x with Pipeline plugin running at v2.x

In the repo root, I have a Jenkinsfile from which shared library is meant to be used.

repo_root /
                 |_____ Jenkinsfile
                 |
                 |_____ vars /
                                     |
                                     |____ buildUtils.groovy

Within the buildUtils.groovy, this is the code snippet:

#!groovy

def call(body) {

    def config = [:]
    body.resolveStrategy = Closure.DELEGATE_FIRST
    body.delegate = config
    body()

    node('linux') {
        checkout scm
        def url = "https://github.com/jenkinsci/${config.name}-plugin.git"
        echo " == URL with repo name == "
        echo "${url}"
    }
}

With this setup in place, running Jenkins build job for this repo, fails with this error:

[Pipeline] End of Pipeline
java.lang.NoSuchMethodError: No such DSL method 'buildUtils' found among steps 

I have been scourging forums here, in SO, in Google but no real solutions seem to 
be available (atleast, it seems to escape my eyes).

What's going wrong here ?

TIA,

can you provide some more info, especially
* how does your Jenkisfile look like
* do you have global shared library configured or per folder?
* which version of the shared library do you adress? Is your script available in that version?
* do you have same script in the internal repo?

Regards, Torsten

Here are some details but am not confident about my setup based on what you're asking.
Maybe, you can help me to clarify what am doing incorrectly.

* how does your Jenkisfile look like

[Ram] : Jenkinsfile content is:

buildUtils("git")
 

* do you have global shared library configured or per folder?

[Ram] : Looks like am missing some configuration here but fail to understand what is it from the plugin docs ?
 

* which version of the shared library do you adress? Is your script available in that version?

[Ram] : Am not sure if understood your question. Shared Groovy library plugin installed is v2.5
 

* do you have same script in the internal repo?

[Ram] : Jenkinsfile and vars/buildUtils.groovy are in the same repo

TIA,
/Ram

Hi

try to separate your Jenkinsfile from the code of your shared library. Usually the shared library provides some global functions that you may re-use in some Jenkinsfile(s)
=> the library is shared code, the Jenkinsfile belongs to your project(s) using that library.

Than, make sure you know what version of the library you are using:
- configure it in Jenkins/manage Jenkins -> global shared library. Here you´ll have to setup repo, branch, credentials to your shared library.
You can also configure it on a per folder base and you may reference it using the annotation@Library('somelib')

It´s pretty well documented at https://github.com/jenkinsci/workflow-cps-global-lib-plugin/blob/master/README.md

Good luck!

Best regards, Torsten

Hi Torsten,

=> the library is shared code, the Jenkinsfile belongs to your project(s) using that library.

[Ram] : I did start writing the library with this separation ; after re-reading the documentation, moved this library has been moved to it's own repo.

Than, make sure you know what version of the library you are using:
- configure it in Jenkins/manage Jenkins -> global shared library. Here you´ll have to setup repo, branch, credentials to your shared library.
You can also configure it on a per folder base and you may reference it using the annotation@Library('somelib')

[Ram] : Updated this configuration too.

With these changes, global shared libs are now usable from the Jenkinsfile.
