[xwiki-devs] [Idea] Use Jenkins 2.0 and the pipeline setup

Hi guys, I saw that at devoxx fr and it seems a great way of working with Jenkins. So I’ve done some POC over the week end, following: * https://jenkins.io/doc/ * https://github.com/jenkinsci/pipeline-plugin/blob/master/TUTORIAL.md Here are the features we could use: * Commit a Jenkinsfile in the SCM (in each branch we use) —> Solves a big part of the issue of saving the jenkins setup + version it (we know who’s modified what and when and it’s in sync with the branches). * Jenkins can automatically create jobs when a Jenkinsfile is noticed. So for example on my local machine I’ve configured a special job for the xwiki-contrib org on github and whenever a project there adds a Jenkinsfile, a job is created (and executed) on jenkins * It’s very visual and very powerful. You program the jenkinsfile in groovy and you have a great DSL to control fully all the steps to execute. * It’s possible to create some reusable libraries so that we don’t duplicate Jenkinsfile content across modules. I still need to finish my research on how to do that. There’s a readFile() API but I need to check how to package them so that they’re not on the FS. For ex this is what I got locally: * https://www.evernote.com/l/AHdeHR61ufBJxrWGIz6FOLtxvwdFf6LXBic * With this simple jenkinsfile: ———— #!groovy node (){ stage "Checkout" env.PATH = "${tool 'Maven 3'}/bin:${env.PATH}" checkout scm stage "Build" def pom = readMavenPom() def projectName = pom.name def projectVersion = pom.version echo "Building ${projectName} - ${projectVersion}" sh 'mvn clean package' stage "Collect Results" step([$class: 'ArtifactArchiver', artifacts: '**/target/*.jar', fingerprint: true]) try { step([$class: 'JUnitResultArchiver', testResults: '**/target/surefire-reports/TEST-*.xml']) } catch (all) { } } ———— Some examples: * https://github.com/jenkinsci/pipeline-examples * https://gist.github.com/chinshr/aa87da01ec28335e3ffd * https://github.com/cloudbees/zendesk-java-client/blob/master/Jenkinsfile Thanks -Vincent
