How to create a GitHub repository and push a sample Java 21 Maven Project

In this Jenkinsfile, you have a single stage named Build and you have a mvn clean package inside the sh step

Use the sh step to define any shell commands.

Push a 02-Jenkinsfile-maven-build file to the GitHub repository

Create the Pipeline named 02-hello-world-maven referring to your GitHub repository and enter Script Path as cicd/02-Jenkinsfile-maven-build

To create a pipeline follow these steps Click here

Build the pipeline and check the Console Output

First cicd/02-Jenkinsfile-maven-build is obtained from the GitHub repository

Then the mvn clean package command is executed

Finally, Jenkins creates a hello-world-1.0-SNAPSHOT.war file in the /var/lib/jenkins/workspace/02-hello-world-maven/target folder.

Important Tips

Tip

Workspace Cleanup: Jenkins does not automatically clean the workspace after a build. The target/ directory from a previous build might persist. Always use mvn clean to ensure a fresh build.

Note

Tool Availability: This example assumes mvn is in the PATH of the agent. In a real-world pipeline, you should use the tools block to explicitly define which Maven version to use.
