Jenkins, a widely used open-source automation server, allows users to extend its functionality through plugins. Jenkins plugin development offers the flexibility to integrate new features, automate processes, and improve overall CI/CD workflows.
Developing a Jenkins plugin requires familiarity with Java, the Jenkins API, and Maven for building the plugin. Here’s a detailed guide on Jenkins plugin development:
Before you start writing a Jenkins plugin, you need to set up your development environment.
Here are the prerequisites:
The simplest way to start a Jenkins plugin project is by using the Jenkins Plugin Parent POM. This is a template that provides basic configurations for building a Jenkins plugin using Maven.
Steps to create a plugin:
Step 1: Set up a new Maven project. You can use the Jenkins Plugin Archetype to create a new plugin skeleton quickly. This is done via Maven by executing the following command in your terminal:
mvn archetype:generate -Dfilter=io.jenkins.archetypes:plugin
This will generate the necessary files and directory structure for your plugin.
Step 2: Define Plugin Details. In the pom.xml file, you'll specify metadata like:
<groupId>com.example.jenkins.plugins</groupId>
<artifactId>my-first-plugin</artifactId>
<version>1.0-SNAPSHOT</version>
<packaging>hpi</packaging>
Here, the artifactId will be the name of your plugin.
A basic Jenkins plugin project structure typically looks like this:
src/
main/
java/
com/
example/
jenkins/
plugins/
MyFirstPlugin.java
resources/
META-INF/
MANIFEST.MF
pom.xml
To implement the functionality of your Jenkins plugin, you will typically extend certain Jenkins classes and implement the required interfaces. For example, if you're creating a simple post-build action, you would extend the Publisher class.
Here's an example of a basic plugin:
package com.example.jenkins.plugins;
import hudson.Extension;
import hudson.tasks.Builder;
import hudson.tasks.BuildStepDescriptor;
import hudson.model.Build;
import hudson.model.AbstractBuild;
import hudson.model.Result;
@Extension
public class MyFirstPlugin extends Builder {
@Override
public boolean perform(AbstractBuild<?, ?> build, hudson.Launcher launcher, hudson.model.BuildListener listener) {
listener.getLogger().println("Hello, Jenkins!");
return true;
}
@Override
public BuildStepDescriptor<?> getDescriptor() {
return (BuildStepDescriptor<?>) super.getDescriptor();
}
}
In this example:
Jenkins plugins need thorough testing before they can be released. You can use the Jenkins testing framework, which provides various ways to simulate a Jenkins environment.
Example of a test using JUnit:
@RunWith(JenkinsRule.class)
public class MyPluginTest {
@Rule
public JenkinsRule jenkinsRule = new JenkinsRule();
@Test
public void testPluginBehavior() throws Exception {
FreeStyleProject project = jenkinsRule.createFreeStyleProject();
project.getBuildersList().add(new MyFirstPlugin());
FreeStyleBuild build = project.scheduleBuild2(0).get();
assertEquals(Result.SUCCESS, build.getResult());
}
}
To build your plugin, you can use Maven. Run the following command from the project root:
mvn clean package
This command will compile your code, run tests, and package the plugin into an .hpi file. The .hpi file is the packaged plugin that can be uploaded to Jenkins.
After building the plugin, you can deploy it to your Jenkins instance:
If you want to share your plugin with the Jenkins community, you can publish it to the Jenkins Plugin Index.
To do this, you'll need to:
After publishing, it’s important to maintain the plugin:
