Jenkins – Initializing Jenkins 2.0 with pipeline in init.groovy.d script

groovyJenkinsjenkins-job-dsljenkins-pipelinejenkins-workflow

For automation, I would like to initialize a Jenkins 2.0 instance with a pipeline job. I want to create a Groovy script that is copied to the /usr/share/jenkins/ref/init.groovy.d/ folder on startup. The script should create a Jenkins 2.0 Pipeline job for processing a Jenkinsfile from SCM.

I cannot find the relevant Javadoc for the 2.0 pipeline classes or examples of how to do this.

Previously, using Job DSL to create a pipeline, I used a Groovy script to create a FreeStyleProject with an ExecuteDslScripts builder. That job would then be the Job DSL seed job.

One option is to use an init script to create a Job DSL seed job to create a Jenkins 2.0 pipeline. It just seems unnecessarily complex.

I am experimenting in this repo: https://github.com/martinmosegaard/vigilant-sniffle

With Job DSL 1.47 (to be released soon) you can use the Job DSL API directly from the init script without the need to create a seed job.

import javaposse.jobdsl.dsl.DslScriptLoader
import javaposse.jobdsl.plugin.JenkinsJobManagement

def jobDslScript = new File('jobs.groovy')
def workspace = new File('.')

def jobManagement = new JenkinsJobManagement(System.out, [:], workspace)

new DslScriptLoader(jobManagement).runScript(jobDslScript.text)

See PR #837 for details.

Jenkins – How to restart Jenkins manually

To restart Jenkins manually, you can use either of the following commands (by entering their URL in a browser):

(jenkins_url)/safeRestart - Allows all running jobs to complete. New jobs will remain in the queue to run after the restart is complete.

(jenkins_url)/restart - Forces a restart without waiting for builds to complete.

Php – How to show error messages in HTML page in PHP

I would prefer Jquery Validation or Ajax based Authentication. But still you can do it this way:

Put your Error Message in Session like this :

$_SESSION['Error'] = "You left one or more of the required fields.";

Than simple show it like this:

if( isset($_SESSION['Error']) )
{
        echo $_SESSION['Error'];

        unset($_SESSION['Error']);

}

In this case you can assign multiple messages in different Operations.
