本文主要演示一下如何用jenkinsfile来编译java服务

安装jenkins

这里使用docker来安装jenkins

docker run --name jenkins-docker \
--volume $HOME/jenkins_home:/var/jenkins_home \
-p 8080:8080 jenkins/jenkins:2.416

之后访问http://${yourip}:8080，然后输入admin密码继续安装

jenkinsfile

pipeline {agent anytools {// Install the Maven version configured as "M3" and add it to the path.maven "M3"}stages {stage('Build') {steps {// Get some code from a GitHub repositorygit 'https://github.com/jglick/simple-maven-project-with-tests.git'// Run Maven on a Unix agent.sh "mvn -Dmaven.test.failure.ignore=true clean package"// To run Maven on a Windows agent, use// bat "mvn -Dmaven.test.failure.ignore=true clean package"}post {// If Maven was able to run the tests, even if some of the test// failed, record the test results and archive the jar file.success {junit '**/target/surefire-reports/TEST-*.xml'archiveArtifacts 'target/*.jar'}}}}
}

这里定义了Build，它先是git拉取代码，然后执行mvn进行编译，最后在post部分在状态为success时使用junit显示测试报告，并归档jar包

小结

jenkins2.x提供了pipeline as code的功能，可以通过jenkinsfile(类似gitlab ci yaml)，使用dsl来定义流水线，这个相比于在界面上配置更为易用和清晰，也容易进行版本化管理。
