常用的项目构建工具集成


Jenkins 常用的项目构建工具集成 01 Maven_git

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


Jenkins 常用的项目构建工具集成 01 Maven_maven_04

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
Apache Maven 3.8.1 (05c21c65bdfed0f71a2f2ada8b84da59348c4c5d)
Maven home: /usr/local/apache-maven-3.8.1
Java version: 1.8.0_282, vendor: AdoptOpenJDK, runtime: /usr/local/jdk8u282-b08/jre

OS name: "linux", version: "4.18.0-80.el8.x86_64", arch: "amd64", family: "unix"

gitlab里面创建一个项目 

Jenkins 常用的项目构建工具集成 01 Maven_apache_05

本地有代码了就可以传上去

Jenkins 常用的项目构建工具集成 01 Maven_jenkins_06

来到这个目录下面将代码上传

[root@jenkins-master ~]# cd devops-maven-service-master
[root@jenkins-master devops-maven-service-master]# ls

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,一般指定私服服务器的源

[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>
-->

 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

这个包就可以直接启动

Pipeline流水线构建


Jenkins 常用的项目构建工具集成 01 Maven_apache_09

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。
