Calling a Jenkins plugin from pipeline

[prasad...@globallogic.com]

Hi,

I have created a simple Jenkins plugin which prints a Hello world on Jenkins console. This plugin is working fine when configured through traditional approach of enabling it through Post Build jobs. Now I am trying to call that plugin through a pipeline code. Below is the code to call the plugin:

step([$class : ' TestExamplePublisher', applications:[name: 'Prasad', lastName: 'P']])

But when I build the job, using build now option. It gives an exception :

What am I missing?

You need to be in a node block for that to work 

node {

  Your step 

}

I have created a node and inside added the pipeline code:

     stage('Build and Run Tests') {
      steps {
  node {
      step([$class : 'TestExamplePublisher', applications:[name: 'PrasadP']])
  }
      }
  }

With this it gave me the following exception:

FSSCM.check completed in 559 milliseconds
Running in Durability level: MAX_SURVIVABILITY
org.codehaus.groovy.control.MultipleCompilationErrorsException: startup failed:

You are mixing declarative and scripted. What kind of pipeline do you want to create?

Example scripted:

https://github.com/jenkinsci/analysis-model/blob/master/Jenkinsfile.local

Example declarative:

https://github.com/jenkinsci/analysis-model/blob/master/Jenkinsfile.declarative

[prasad...@globallogic.com]

I want a declarative pipeline. I have a declarative pipeline configured already, so I would not want to change that.

[Ullrich Hafner]

What about

pipeline {
    agent 'any'
    stages {
        stage ('Build and Analysis') {
            steps {

                [$class : 'TestExamplePublisher', applications:[name: 'PrasadP']]
            }
        }
    }

}

You will get faster feedback for such pipeline questions on the users list.

My Complete pipeline looks like this:

import hudson.model.*

checkout filesystem(clearWorkspace: false, copyHidden: false, path: 'C:\\java-junit-sample-master\\java-junit-sample-master')

pipeline {

    agent any

    stages {

        stage('Build and Run Tests') {

            steps {

node {

    step([$class : 'TestExamplePublisher', applications:[name: 'PrasadP']])

}

            }

        }

    }

}

And the plugin which I am referring to is (https://github.com/pritic/testExample.git).

For Declarative, you would probably want this in a `post` block, and
you should add a `@Symbol` to your publisher.
