Shared library command not working

Using Jenkins
1

Hey all,

I’m trying to make shared steps between two pipelines but it doesn’t seem to be properly loading1

What I tried to do (all the files in the same repository/clone):

// vars/submodules.groovy
def call() {
    sh 'git pull'
    sh 'git submodule update --init'
    sh 'git submodule status'
}

And my pipeline

// Jenkinsfile
pipeline {
   agent { ... }
   options { ... }
   stages {
      stage('Submodules') {
          steps {
              submodules()
          }
      }
   }
}

But every time the pipeline runs, I get an error about the submodules call:

java.lang.NoSuchMethodError: No such DSL method 'submodules' found among steps [archive, ...]

What’s the proper way to split steps this way? Is there a plugin that needs to be present to make this work automatically? We are using Jenkins 2.440.3.

1: Actually, I’m breaking my current pipeline into smaller calls to be reused in a new one.

you need the plugin Pipeline: Groovy Libraries installed.
You can configure a shared library to be loaded implicitly. See
Extending with Shared Libraries for more details

Hm… But I do have Groovy Libraries installed. And I’m following (I hope) what’s described in Defining Custom Steps.
