Using Jenkins to build Maven Projects
Jenkins configuration
- Install jenkins
- jdk 17
- Install and configure maven in Jenkins (Master Node)
- Lets build spring petclinic Refer Here
- software requirements
- jdk 17
- maven
- software requirements
- Create a free style project to build spring petclinic
- Free style project sections
- General: This represents the project information
- Source Code Managent: This represent the code to be used for ci/cd pipelines
- Build Triggers: This represent when to build
- Build Periodically: If the project has to be build based on schedule, write cron expression into this Refer Here
- Poll SCM: this represents jenkins polling scm (asking git) and the cron expression represents how frequently should it ask
- Build Environment: This represents the environmental configuration
- Build Steps: These are actual activities that are performed during execution.
-
Post Build actions: Actions to be performed after completion of build
-
Now we can wait for the trigger to call the job or trigger build manually
- In Jenkins we can have multiple versions of java, maven etc and we can handle these by configuring jenkins
- To fix the maven 3.6.3 issue we had install 3.9 and used full path for package
- Test results
Jenkins Terms
- Jenkins Home: Jenkins home is a folder where jenkins stores all of is configuration. In the above case the workspace is
/var/lib/jenkins. If you want to change the workspace deal withJENKINS_HOME - Backup of Jenkins is backup of Workspace
- Project: This contains the actvity that needs to be performed on triggers.
- This project is stored as xml file in workspace
- Types:
- Freestyle project: This is UI based configuration
- Pipeline: This is instructions expressed in some code format.
- Build: This represents the execution of project. Every build for a project has a running number called as Build id
- Node: This represents the machine on which build can be executed.
- Each Node can be configured to handle multiple builds by executors.
