Building Code and Unit Testing Using Jenkins

• It depends on Technology (EcoSystem)
• Every Technology/Application has different set of build tools and unit testing
• In Jenkins Approach is
  • Install necessary tools
  • configure tools for Jenkins user
  • In the build section execute these commands

Example: Building Docker Image

• Even if you are not familiar with docker, we can still build this.
• First lets install Docker. Login as Jenkins user and do the following

curl -fsSL https://get.docker.com -o get-docker.sh
sh get-docker.sh
sudo usermod -aG docker jenkins
sudo service jenkins restart # when it is configured in jenkins
exit
# relogin
docker info

• Lets look at commands

git clone https://github.com/DevProjectsForDevOps/StudentCoursesRestAPI.git 
docker image build -t studentcourserestservice:1.0 .

• Create a free style Jenkins project, Select the Source Code Management Tab and give git details, and then to build section and Execute shell

docker image build -t studentcourserestservice:1.0 .

Build/Compile/test Java Using Maven.

• Building Java Code

  • Compiling Each and every .java file
  • archive (zip) all the generated .class files into war/jar/ear

• To do this build activity, there are many build tools

  • ANT
  • Maven
  • Gradle

• In this series we restrict ourselves to Maven

• Maven Installation on ubuntu

sudo apt-get update
sudo apt-get install maven -y
mvn -v
