Shortcomings of Jenkins

  • Jenkins is functional driven , so its not very to easy to use and has a lot of learning curve making it hard for beginners to understand
  • It lack analytics although there are plugins that can be used , it's still not enough which makes it a headache for production team
  • Although Jenkins has lot of plugins available , the very useful ones are a few and you will have to learn to use different plugins each time you need something.
  • Jenkins plugins also has a possibility of backdoor i.e. some plugins can be created by malicious attackers and if any developer installs it then it's going to become a major issue for the organization.
  • Changes made by a developer will not be visible to another developer of the team. It makes tracking difficult in large projects.
