New Build Job in Jenkins Freestyle Project : Step by Step Procedure:

Step 1:Login to Jenkins

• To create a Jenkins freestyle job, log on to your Jenkins dashboard by visiting your Jenkins installation path. Usually, it will be hosted on localhost at http://localhost:8080 If you have installed Jenkins in another path, use the appropriate URL to access your dashboard as shown in the below Jenkins job creation example.
  • 

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,
• Enter the name of the item you want to create. We shall use the “Hello world” for this demo.
• Select Freestyle project
• Click Okay

Step 4: Enter Project details

• Enter the details of the project you want to test.
  • 

Step 5: Enter repository URL

• Under Source Code Management, Enter your repository URL. We have a test repository located at https://github.com/kriru/firstJava.git
  • 
• It is also possible for you to use a local repository.
• If your GitHub repository is private, Jenkins will first validate your login credentials with GitHub and only then pull the source code from your GitHub repository.

Step 6: 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 Windows batch command” and add the commands you want to execute during the build process.
  • 
• Here, I have added the java commands to compile the java code.
• I have added the following windows commands:
• javac HelloWorld.java
• java HelloWorld
  • 

Step 7: Save the project

• When you have entered all the data,
• Click Apply
• Save the project.

Step 8: Build Source code

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

Step 9: Check the status

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

Step 10: 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 HelloWorld program hosted on GitHub. Jenkin pulls the code from the remote repository and builds continuously at a frequency you define.
