Jenkins is an open-source non-stop integration server written in java for orchestrating a sequence of actions to attain the continuous integration technique in an automated style. Jenkins helps the complete improvement lifestyles cycle of software program from constructing, testing, documenting the software program, deploying, and different stages of the software improvement existence cycle.
Jenkins is a widely used application around the world that has around 300k installations and growing day by day. By using Jenkins, software companies can accelerate their software development process, as Jenkins can automate build and test at a rapid rate.
It's far a server-based application and requires a web server like apache tomcat. The purpose Jenkins software program becoming so famous is that of its tracking of repeated responsibilities that arise throughout the development of a challenge. For example, in case your group is developing an undertaking, Jenkins will constantly take a look at your task builds and show you the mistakes in the early stages of your development.
Advantages of Jenkins:-

Disadvantages of Jenkins:-
Following are some cons of the Jenkins tool:
All plug-ins are not compatible with the declarative pipeline syntax.
Jenkins has many plug-ins in its library, but it seems like they are not maintained by the developer team from time to time. This is when it becomes very important that whatever plug-ins you are going to use; are getting a regular update or not.
Lots of plug-ins have a problem with the updating process.
It is dependent on plug-ins; sometimes, you can’t find even basic things without plug-ins.
Jenkins UI is not user-friendly in comparison to current UI Technologies. It cannot be very clear for the first-time user.
Managing of Jenkins dashboard is hard when we have too many jobs to be executed.
Changes made by a developer will not be visible to another developer of the team; only the manager can have its access. It makes tracking difficult in large projects.
Although many plug-ins are available, it does not provide the analytical support in the end to finish the deployment cycle. It leads to the creation of difficulties in the tracking of the project deployment.
The error message is not clear sometimes. It becomes hard to find out what went wrong.
You have to maintain your infrastructure by yourself.
It is not easy to install and configuration the Jenkins tool.
