Plugin Information

View JenkinsLint on the plugin site for more information.

Detects whether your Jenkins configuration follows those best practices 

This plugin has mainly two goals:

  • To make it easier to detect issues in your Jenkins configuration that will cause Jenkins to blow up when you attempt to run those jobs.
  • To encourage discussion within the Jenkins community on the more subjective stuff. Having a set of checks to base discussion on helps drive out what we as a community think is good style.

Summary

Jenkins is an awesome Automation System, and there are a bunch of people using it in different ways, for example: developers, testers, automation, build engineers, release engineers, scrum master, product owner and so on. Unfortunately, as the number of jobs grows, maintaining them becomes tedious, and the paradigm of no using a predefined set of best practices falls apart.

The Jenkins Lint plugin attempts to solve this problem by allowing jobs to be evaluated with some predefined best practices. The goal is for your team to be able to define those best practices to be related to their project.

Manually reviewing those jobs wouldn't be too hard, but doing the same thing all over again for every new job or for a hundred other projects is where it gets difficult and tedious. This provides a much more powerful way of analyzing them.

Usage

You can find it under <jenkins_url>/jenkinslint or reach it via links in the sidepanel of the main page. You don't need to do anything else, just click on the Jenkins Lint link and those Lint checkers will be shown.

Property

Version

Notes

org.jenkins.ci.plugins.jenkinslint.JobLintAction.disabled

false

0.9.0

Deprecated since 0.10.0

 

By default you will see the below view:

 

If you disabled then:

Enable/Disable with Groovy script

You can easily disable/enable Checkers from the Script console, from version 0.10.0 onwards!

import org.jenkins.ci.plugins.jenkinslint.JenkinsLintGlobalConfiguration
import jenkins.model.GlobalConfiguration

// Disable Globally
JenkinsLintGlobalConfiguration.all().get(JenkinsLintGlobalConfiguration.class).setGlobalEnabled(false)

// Disable JobAction
JenkinsLintGlobalConfiguration.all().get(JenkinsLintGlobalConfiguration.class).setJobActionEnabled(false)

// Disable Lint
JenkinsLintGlobalConfiguration.all().get(JenkinsLintGlobalConfiguration.class).setCleanupWorkspaceCheckerEnabled(false)
 
// More properties in the JenkinsLintGlobalConfiguration class: https://github.com/jenkinsci/jenkinslint-plugin/blob/a97f3e17b14d7410164bb4bea50ba5968a3a97b8/src/main/java/org/jenkins/ci/plugins/jenkinslint/JenkinsLintGlobalConfiguration.java#L18-L45


API

You can retrieve jenkins lint defects by requesting the following URLs :

  • <jenkins/hudson_url>/jenkinslint/api/json?depth=2&pretty=true
  • <jenkins/hudson_url>/jenkinslint/api/xml?depth=2


And also you can retrieve lint defects per job/agents:

  • <jenkins/hudson_url>/job/<your_job>/jenkinslint/api/json?depth=2&pretty=true
  • <jenkins/hudson_url>/job/<your_job>/jenkinslint/api/xml?depth=2
  • <jenkins/hudson_url>/computer/<agent>/jenkinslint//api/json?depth=2&pretty=true
  • <jenkins/hudson_url>/computer/<agent>/jenkinslint//api/xml?depth=2

Workaround

There is already a known issue in the initial version 0.1.0 , Workspace Cleanup Plugin is a required dependency otherwise JenkinsLint will fail when analyzing those Jobs
