Jenkins 常用的项目构建工具集成 01 Maven
常用的项目构建工具集成
前端的打包工具，一般使用的都是npm
Java项目构建工具
初始化一个springboot项目 https://start.spring.io/
maven去打包的时候，下面都会有一个xml文件，叫pom.xml这个文件，这个文件就定义了项目的依赖项，通过各种结构化的数据来定义。
这样就生成了maven测试项目的一个过程
Maven
官网：http://maven.apache.org/download.cgi Maven是一个项目的构建依赖管理工具。通常项目的根目录会存在一个pom.xml文件（该文件用于定义项目的依赖包信息和构建配置）
经常要做的就是如何在流水线里面进行打包
Maven安装配置
maven也是依赖JDK的，所以要先将java_home配置好
[root@jenkins-master ~]# java -version
openjdk version "1.8.0_282"
OpenJDK Runtime Environment (AdoptOpenJDK)(build 1.8.0_282-b08)
OpenJDK 64-Bit Server VM (AdoptOpenJDK)(build 25.282-b08, mixed mode)
[root@jenkins-master ~]# tail -n6 /etc/profile
export JAVA_HOME=/usr/local/jdk8
export PATH=$JAVA_HOME/bin:$PATH
export GROOVY_HOME=/usr/local/groovy-3.0.7
export PATH=$GROOVY_HOME/bin:$PATH
export M2_HOME=/usr/local/apache-maven-3.8.1
export PATH=$M2_HOME/bin:$PATH### 下载
wget https://mirrors.bfsu.edu.cn/apache/maven/maven-3/3.8.1/binaries/apache-maven-3.8.1-bin.tar.gz
tar zxf apache-maven-3.8.1-bin.tar.gz -C /usr/local/
cd /usr/local/apache-maven-3.8.1/
pwd /usr/local/apache-maven-3.8.1
### 配置环境变量
vi /etc/profile
export M2_HOME=/usr/local/apache-maven-3.8.1
export PATH=$M2_HOME/bin:$PATH
source /etc/profile
### 验证
mvn -v

本地有代码了就可以传上去
来到这个目录下面将代码上传

resource文件夹里面存放着配置文件
Maven 常用命令
- mvn clean 清理构建目录
- mvn clean package 打包 (这里会有单元测试的过程)
- mvn clean install 打包部署
- mvn clean test 单元测试
- mvn clean package -f ../pom.xml -f指定pom位置\
- mvn clean package -DskipTests / -Dmaven.test.skip=true 跳过单测
- mvn deploy 发布包到制品库
打包的时候会下载很多依赖，阿里云maven源https://developer.aliyun.com/article/597934
下面是修改插件源
[root@jenkins-master ~]# vim /usr/local/apache-maven-3.8.1/conf/settings.xml
<mirror>
<id>alimaven</id>
<mirrorOf>central</mirrorOf>
<name>aliyun maven</name>
<url>http://maven.aliyun.com/nexus/content/groups/public/</url>
</mirror>maven下载的包都会缓存在目录当中
<!-- localRepository
| The path to the local repository maven will use to store artifacts.
|
| Default: ${user.home}/.m2/repository
<localRepository>/path/to/local/repo</localRepository>
-->
[root@jenkins-master repository]# ls
aopalliance backport-util-concurrent classworlds commons-codec commons-logging jakarta junit org
asm ch com commons-io io javax net这里多了一个target目录，最关键的就是这个应用包demo-0.0.1-SNAPSHOT.jar

Pipeline流水线构建
def buildTools = ["maven": "/usr/local/apache-maven-3.8.1"]
pipeline{
agent {label "build"}
stages{
stage("GetCode"){
steps{
script{
println("下载分支代码----->${env.branchName}")
checkout([$class: 'GitSCM', branches: [[name: "${env.branchName}"]], extensions: [], userRemoteConfigs: [[credentialsId: '823b86fe-2c1b-466e-b0c3-66ae6991449d', url: "${gitHttpURL}"]]])
}
}
}
stage("Build"){
steps{
script{
sh "${buildTools["maven"]}/bin/mvn clean package"
}
}
}
}
}单元测试
maven这里有时候会找不到，使用绝对路径，如下使用
def buildTools = ["maven": "/usr/local/apache-maven-3.8.1"]
pipeline{
agent {label "build"}
stages{
stage("GetCode"){
steps{
script{
println("下载分支代码----->${env.branchName}")
checkout([$class: 'GitSCM', branches: [[name: '*/master']], extensions: [], userRemoteConfigs: [[credentialsId: '823b86fe-2c1b-466e-b0c3-66ae6991449d', url: "${gitHttpURL}"]]])
}
}
}
stage("Build"){
steps{
script{
sh "${buildTools["maven"]}/bin/mvn clean package"
}
}
}
stage("UnitTest"){
steps{
script{
sh "${buildTools["maven"]}/bin/mvn test"
}
}
}
}
}单元测试有个插件junit的报告，下面是测试报告的目录
[root@jenkins-master devops-maven-service-master]# ls target/surefire-reports/
com.example.demo.DemoApplicationTests.txt TEST-com.example.demo.DemoApplicationTests.xml下面的路径是相对于workspace来说的
如果单元测试失败就收集不到了，所以呢这里需要添加一个post
def buildTools = ["maven": "/usr/local/apache-maven-3.8.1"]
pipeline{
agent {label "build"}
stages{
stage("GetCode"){
steps{
script{
println("下载分支代码----->${env.branchName}")
checkout([$class: 'GitSCM', branches: [[name: '*/master']], extensions: [], userRemoteConfigs: [[credentialsId: '823b86fe-2c1b-466e-b0c3-66ae6991449d', url: "${gitHttpURL}"]]])
}
}
}
stage("Build"){
steps{
script{
sh "${buildTools["maven"]}/bin/mvn clean package"
}
}
}
stage("UnitTest"){
steps{
script{
sh "${buildTools["maven"]}/bin/mvn test"
}
}
post{
success{
script{
junit 'target/surefire-reports/*.xml'
}
}
}
}
}
}
在企业里面会用nexus去搭建一个私服，那么就可以使用本地私服了，就不需要去拉取外网的包了。最后项目打包时候需要的参数找开发人员去要就行了。
