Jenkins is an Open Source automation server which is written in java. It helps us to automate the software development with Continuous integration. It does compile the code if he finds any error it reports to the development team by doing this it’s reducing the code compile time of development team.
It increases the software delivery process as if codes fails at some moment it sends the report to developer team to see the issues. If any changes comes in software it starts complies them.
