Jenkins Job Builder / JJB "wrappers" don't have any effect on generated jobs

Question

I'm currently trying to realize job timeouts, etc vi "wrappers" as described in the docs and some examples.

Regardless whether I apply wrappers directly on jobs or on job templates or defaults, I can't see any effect on the generated XML.

There is some bug report from a couple of years ago but despite it sounds quite similar I think the solution does not apply for me since the report is Jenkins specific but my generated config does not contain a <buildWrappers> section at all!

For example the following YAML should generate a timeout section:

- job:
    name: bla
    project-type: "pipeline"
    dsl: |
      sh("hello world")
    wrappers:
      - timeout:
          timeout-var: 'BUILD_TIMEOUT'
          fail: true
          elastic-percentage: 150
          elastic-default-timeout: 90
          type: elastic

Generated output:

<?xml version="1.0" encoding="utf-8"?>
<flow-definition plugin="workflow-job">
  <definition class="org.jenkinsci.plugins.workflow.cps.CpsFlowDefinition" plugin="workflow-cps">
    <script>sh(&quot;hello world&quot;)
</script>
    <sandbox>false</sandbox>
  </definition>
  <actions/>
  <description>&lt;!-- Managed by Jenkins Job Builder --&gt;</description>
  <keepDependencies>false</keepDependencies>
  <properties>
    <org.jenkinsci.plugins.workflow.job.properties.DisableConcurrentBuildsJobProperty/>
  </properties>
</flow-definition>

Any idea what I'm doing wrong here?

I'm using jenkins-job-builder v3.12.0 on Python 3.9

Ok, found it

    def gen_xml(self, xml_parent, data):
        if data.get("project-type", "freestyle") == "pipeline":
            logger.debug("Build wrappers skipped for Pipeline job")
            return

Looks like the documentation just didn't mention that wrappers don't work for the only job type I'm using :)
