Open source Jenkins is a popular tool for test automation and implementing shifting left through continuous integration and continuous deployment. Followed by two blogs introducing how to install Jenkins on Windows (click here) and on Ubuntu (click here), a third way is to install Jenkins with a WAR (Web application ARchive) file version of Jenkins. This option can be used on any Java-supporting platform or OS.

First, you will need to install JDK. Jenkins supports Java 8. If you don’t know how to install Java, look at this blog. Now that Java is installed, we can proceed with Jenkins.

Installing Jenkins

1. Click here to download the latest Jenkins WAR file.

2. Copy the jenkins.war file to the folder you want. I created a folder named Jenkins in the path C:\Program Files (x86) and copied the jenkins.war file to it.

8. To unlock Jenkins, paste the random password that you wrote down in the previous step or copy it from the user account folder, from the file C:\Users\<your_user_account_folder_name>\.jenkins\secrets\initialAdminPassword. Paste it in the Administrator password field and click on the “Continue” button.
