java command to start jenkins

To start Jenkins using the command line in Java, you will need to have the Jenkins WAR file installed on your system. The Jenkins WAR file is a self-contained package that contains all the necessary code and resources to run Jenkins as a standalone web application.

To start Jenkins using the command line, follow these steps:

1. Open a command prompt or terminal window.
2. Navigate to the directory where the Jenkins WAR file is located.
3. Run the following command:

java -jar jenkins.war

This will start the Jenkins web application and make it available at http://localhost:8080 by default. You can access the Jenkins dashboard and configure your Jenkins instance using a web browser.

Note that starting Jenkins using the command line like this is only suitable for testing or development purposes. For production environments, it is recommended to use a more robust method for running Jenkins, such as using a dedicated servlet container or deploying Jenkins as a standalone application using a system service.
