Introduction to Install Jenkins
Jenkins is a Continuous Integration and delivery tool. It helps the developers in their development process. There is always a huge demand for some improvement and multi-tasking applications. Jenkins is one such tool that can help developers with code integration and delivery facilities altogether.
So, as we know that developers are working on code development and there is a repository allocated for their work to store and share among the team. This repository can be Git, VSO, Jira or any other tool. Jenkins will make sure that whatever the latest commits that happen to the repository do not get spoiled, it runs then and checks if everything is fine or not. If there is any kind of issue related to builds, it has a feature to report the concerned person via email notification.
Jenkins is developed in Java and it is an open source tool. Users who want Jenkins in their system – download Java (either JDK or JRE) in your system before.
