Integration of common project construction tools
The front-end packaging tools generally use npm
Java project builder
Initialize a springboot project https://start.spring.io/
When maven goes to package, there will be an xml file called POM xml file, which defines the dependencies of the project through various structured data.
This is a process of generating maven test projects
Maven
Official website: http://maven.apache.org/download.cgi Maven is a project build dependency management tool. Usually there is a POM in the root directory of the project XML file (this file is used to define the dependent package information and build configuration of the project)
What we often have to do is how to package in the assembly line
Maven installation configuration
maven also relies on JDK, so you need to use Java first_ Home configured

Create a project in gitlab
If there is a local code, you can pass it on
Go to this directory and upload the code

Maven common commands
- mvn clean # clean up the build directory
- mvn clean # package (there will be a unit test process here)
- mvn clean install package deployment
- mvn clean test unit test
- mvn clean package -f ../pom.xml - f specifies the POM location\
- mvn clean package -DskipTests / -Dmaven.test.skip=true skip single test
- mvn deploy publish package to artifact Library
Many dependencies will be downloaded when packaging. Alibaba cloud maven source https://developer.aliyun.com/article/597934
The following is the modified plug-in source
[root@jenkins-master ~]# vim /usr/local/apache-maven-3.8.1/conf/settings.xml

<id>alimaven</id>
<mirrorOf>central</mirrorOf>
<name>aliyun maven</name>
<url>http://maven.aliyun.com/nexus/content/groups/public/</url>
</mirror>The packages downloaded by maven will be cached in the directory

Unit test
maven is sometimes not found here. Use the absolute path as follows
def buildTools = ["maven": "/usr/local/apache-maven-3.8.1"]
pipeline{
agent {label "build"}
stages{
stage("GetCode"){
steps{
script{
println("Download branch code----->${env.branchName}")

}
}
}
stage("UnitTest"){
steps{
script{
sh "${buildTools["maven"]}/bin/mvn test"

}
}
}The unit test has a report of the plug-in junit. The following is the directory of the test report
[root@jenkins-master devops-maven-service-master]# ls target/surefire-reports/ com.example.demo.DemoApplicationTests.txt TEST-com.example.demo.DemoApplicationTests.xml
The following path is relative to workspace
If the unit test fails, it will not be collected, so you need to add a post here
