DevOps Classroom Series – 11/May/2020

Maven (Contd..)

Maven Plugins

• In maven what we give is a goal (mvn package)
• Maven works with plugins to acheive goals. General plugins
  • Create jar/war file
  • Compile code
  • unit testing code
  • Creating docs
  • Creating Reports
• If your org uses third party plugins for build activities add the following section to the pom.xml

  <build>
	<plugins>
	  <plugin>
			
	  </plugin>
    </plugins>
  </build>

Snapshots VS Releases

• If your build is not a release, then it is called as SNAPSHOT. See the version <version>1.0-SNAPSHOT</version> in pom below

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xmlns="http://maven.apache.org/POM/4.0.0"
  xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd">
  
  <modelVersion>4.0.0</modelVersion>
  <groupId>com.qualitythought.devops</groupId>
  <artifactId>hello-maven</artifactId>
  <version>1.0-SNAPSHOT</version>
  
  
  <dependencies>
	<dependency>
	  <groupId>com.google.guava</groupId>
	  <artifactId>guava</artifactId>
	  <version>29.0-jre</version>
	</dependency>
	
	
	<dependency>
		<groupId>junit</groupId>
		<artifactId>junit</artifactId>
		<version>4.13</version>
		<scope>test</scope>
	</dependency>

  </dependencies>
  
</project>

• If your version doesn’t have SNAPSHOT Term or if it has RELEASE TERM, It is considered to be release version, For the Release Version would be <version>1.1</version> or <version>1.1.RELEASE</version>

Test Results and Package Locations

• Generally Test results will be in target/surefire-reports/*.xml
• Package will be in target folder

Lets Try to Build Java Project in Jenkins and show test results

• Create a freestyle project with Build using Invoke top level maven targets
• After Build Navigate to workspace folder
• Lets archive the Package for every build
• Lets also show the test results to the user
  • Jenkins understands test results which are generated in Junit xml format or some users show html file
