Step 1: On the Jenkins dashboard, click on “New Item” to create a new job.
Step 2: Enter a name for your job and select the appropriate job type (e.g., Freestyle project, Pipeline, etc.).
Step 3: Configure the job by providing necessary details such as the source code repository, build triggers, build steps, and post-build actions.
Step 4: Save the job configuration.
Step 5: On the Jenkins dashboard, locate your newly created job and click on “Build Now” to trigger a build.
Step 6: Jenkins will execute the defined build steps and provide feedback on the build status and any issues encountered.
