triggering another jenkins job from jenkinsfile in pipeline

Question

I am trying to invoke a separate jenkins job whose direct job url is https://jenkins.example.com/job/jobName/. This job runs with one parameter name "branch", whose value is "Master".

Below is how I am giving in my Jenkinsfile, but when I run it, gives me error

ERROR: No item named https://jenkins.example.com/job/jobName found

if ("${params.buildParam}" == 'test' || !params.buildParam ){
  stage('Test') {
    def job = build job: 'https://jenkins.example.com/job/jobName/', parameters: [[$class: 'StringParameterValue', name: 'branch', value: 'Master']]
  }
}

Answer 1

The build step takes a job name as parameter, not a URL. So try

build job: '/jobName'

to refer using the absolute path. Depending on where your pipeline job is, you might use something like the following as well:

build job: '../../jobName/'

btw. you can avoid string interpolation here:

if (params.buildParam == 'test' ...)
