Jenkins : Build Freestyle job from a pipeline

Question

I've I have 2 Jenkins Job: A freestyle job 'A' and Pipeline 'B'

I want to build 'A' job inside 'B' in one of my stages.

I've tried building it this way inside my jenkins file:

stage('Running A') {
    agent none
     
    steps{
        build job: 'A'
    }
}

but it doesn't work. I get:

no item named 'A' found

Is there anyone who's familiar with this kind of method please guide me.

Answer 1

Instead of build job: 'A' I've changed it to build 'A'

That's how it worked for me.

Answer 2

It's possible that you're not using the correct job name.

Get the job name of A by REST API at the bottom left or updating the script to run echo env.JOB_NAME && exit 1 temporarily.
