Jenkins custome pipline

This repo describes how to setup a Jenkins job with a custome pipeline to a Github repository.

Project setup

Add a file named Jenkinsfile to your root directory with the following code.

pipeline {
    agent any

    tools {
        maven 'Maven'
        jdk 'jdk-17'
    }

    stages {
        stage('Build') {
            steps {
                sh 'mvn clean install -DskipTests'
            }
        }
        stage('jenkins-custom-pipeline') {
            steps {
                sh 'mvn -Dmaven.test.failure.ignore=true test'
            }
        }
    }

    post {
        always {
            publishCoverage adapters: [jacocoAdapter('target/site/jacoco/jacoco.xml')]
            junit 'target/surefire-reports/*.xml'
        }
    }
}

Add the correct maven plugins to your POM file

			<plugin>
				<groupId>org.apache.maven.plugins</groupId>
				<artifactId>maven-surefire-plugin</artifactId>
				<version>2.22.2</version>
			</plugin>
			<plugin>
				<groupId>org.apache.maven.plugins</groupId>
				<artifactId>maven-surefire-report-plugin</artifactId>
				<version>2.22.2</version>
			</plugin>
			            <plugin>
                <groupId>org.jacoco</groupId>
                <artifactId>jacoco-maven-plugin</artifactId>
                <version>0.8.8</version>
                <executions>
                    <execution>
                        <id>prepare-agent</id>
                        <goals>
                            <goal>prepare-agent</goal>
                        </goals>
                    </execution>
                    <execution>
                        <id>report</id>
                        <phase>test</phase>
                        <goals>
                            <goal>report</goal>
                        </goals>
                    </execution>
                </executions>
            </plugin>

Pipline setup in Jenkins

1. First create a new Item and select Pipeline.

2. Preferably discard your builds. You can choose the maximum amount of builds.

3. Fill in the url to your repository

4. To schedual your builds use Poll SCM. In the example bellow the trigger is set to every 5 minutes

5. After this set the Pipeline script from SCM (Git). To add credentials you have to create a token. This you can do via Github usersettings > Developer settings > Personal token.

You also need to specify your branch. In the case of Github this will be main.

After this you are ready to go.
