How to Create a New Build Job in Jenkins

Step by Step process to create job in Jenkins

Step 1) Login to Jenkins

To create a Jenkins freestyle job, log on to your Jenkins dashboard by visiting your Jenkins installation path. it will be hosted on localhost at http://localhost:8080

Step 2) Create New Item

Click on “New Item” at the top left-hand side of your dashboard.

Step 3) Enter Item details

In the next screen,

  1. Enter the name of the item you want to create. We shall use the “my_1_project” for this demo.
  2. Select Freestyle project
  3. Click Okay

Step 4) Enter repository URL

Under Source Code Management, Enter your repository URL. We have a test repository located at

Step 5) Tweak the settings

Now that you have provided all the details, it’s time to build the code. Tweak the settings under the build section to build the code at the time you want. You can even schedule the build to happen periodically, at set times.

Under build,

1. Click on “Add build step

2. Click on “Execute shell” and add the commands you want to execute during the build process.

Step 6) Save the project

When you have entered all the data,

  1. Click Apply
  2. Save the project.

Step 7) Build Source code

Now, in the main screen, Click the Build Now button on the left-hand side to build the source code.

Step 8) Check the status

After clicking on Build now, you can see the status of the build you run under Build History.

Step 9) See the console output

Click on the build number and then Click on console output to see the status of the build you run. It should show you a success message, provided you have followed the setup properly as shown in the below Jenkins create new job example.

In sum, we have executed a my_1_project program hosted on GitHub. Jenkin pulls the code from the remote repository and builds continuously at a frequency you define.
