Jenkins Build: Set Up Freestyle Project in Jenkins

January 25, 2022

Introduction

Jenkins is an open-source server used for automating software development and deployment. It allows developers to create repeatable jobs that contain all the code necessary to build an application.

In this tutorial, we will define what a Jenkins Freestyle Project is and show you how to set one up.

Prerequisites

What Is a Build Job?

A Jenkins build job contains the configuration for automating a specific task or step in the application building process. These tasks include gathering dependencies, compiling, archiving, or transforming code, and testing and deploying code in different environments.

Jenkins supports several types of build jobs, such as freestyle projects, pipelines, multi-configuration projects, folders, multibranch pipelines, and organization folders.

Note: Learn more about how Jenkins works in our Jenkins tutorial for beginners.

What is a Jenkins Freestyle Project?

Jenkins freestyle projects allow users to automate simple jobs, such as running tests, creating and packaging applications, producing reports, or executing commands. Freestyle projects are repeatable and contain both build steps and post-build actions.

Even though freestyle jobs are highly flexible, they support a limited number of general build and post-build actions. Any specialized or non-typical action a user wants to add to a freestyle project requires additional plugins.

How to Set up a Build Job in Jenkins

3. Enter the commands you want to execute in the Command field. For this tutorial, we are using a simple set of commands that display the current version of Java and Jenkins working directory:

java -version
dir

4. Click the Save button to save changes to the project.

Step 3: Build the Project

1. Click the Build Now link on the left-hand side of the new project page.

Use the Build Now link to build the a new project version

2. Click the link to the latest project build in the Build History section.

Click the link to open the latest build version

3. Click the Console Output link on the left-hand side to display the output for the commands you entered.

Click the link to open the build console output

4. The console output indicates that Jenkins is successfully executing the commands, displaying the current version of Java and Jenkins working directory.
