Let's compare how are reported a pipeline job and a freestyle job when they are triggered as parametrized build in the Post-Build section.

In my example I have a freestyle job :

test-parametrizedPlugin-main-job that calls 2 jobs one freestyle and one pipeline :

• test-parametrizedPlugin-called-pipeline-job
• test-parametrizedPlugin-called-freestyle-job

1- In the status page of the job we see in the Downstream Projects part, the pipeline job is missing

2- In the console log the called pipeline job is not reported but started
