Pipeline plugins (a.k.a. preset plugins) are micro tools that allow you to enhance and refine the CI/CD workflow of your application by adding new features, integrating with external tools, and automating tasks.
Unlike custom scripts, preset plugins come bundled with specific variables and conditions that help you make the plugins work seamlessly with your CI/CD pipeline.
Some plugins are meant for pre-build/post-build, while some are meant for pre-deployment/post-deployment.
