Scripted Pipeline
Scripted Pipeline is a domain-specific language (DSL) based on Groovy for defining continuous integration and delivery (CI/CD) pipelines in Jenkins, an open-source automation server. It allows developers to write pipeline logic as code using a flexible, imperative scripting approach, enabling complex workflows with conditional logic, loops, and custom functions. This method provides fine-grained control over the build, test, and deployment processes, making it suitable for advanced automation scenarios.
Developers should learn Scripted Pipeline when they need to implement complex, dynamic CI/CD workflows in Jenkins that require custom logic beyond what Declarative Pipeline offers, such as handling multiple branches, integrating with external systems, or performing advanced error handling. It is particularly useful in environments where pipeline behavior must adapt based on runtime conditions or when reusing code across multiple projects through shared libraries. Use cases include automating multi-stage deployments, running parallel jobs with dependencies, or integrating with custom tooling and APIs.
