Playing with Plugins

In this lab we will explore various plugins of Jenkins :

• Create a day1 folder and move all your projects to that folder.
• Create a Maven type job to compile your project.
• Install Build Monitor view plugin to view the status of various jobs in one single place.
• Install Monitoring Plugin to visualize the health of Jenkins.
• Update Job to be invoked via REST API.
• Also enable the capability to fetch the branches dynamically.

Create a folder using the Folder plugin

• Go to the "New Item" and give the name "day1" and select job type "Folder"

• Go to all jobs which we have created till now and click on the down arrow on the right side of the job and select "Move" and provide the path of the new folder

Configuring a Maven Job

• Go to Manage Jenkins > Manage Plugins and click on the available tab.

• Search for maven-plugin and install it without restart

• Once the installation is done, restart Jenkins by URL.

http://your_jenkins_url:8080/restart

• Create a new job with the name <team_name>-maven-project-plugin and click on the maven project job type

• Go under the "Source Code Management" and select the Git option and provide the repository URL of the worked repo.

• Go to the "Build" section and change the values of Root POM to SampleJavaWebApp/pom.xml and "Goal and options" to clean package
