Implementing Custom DSL with Groovy in 20 Minutes

Discover how to implement custom Domain-Specific Languages (DSLs) using Apache Groovy in this comprehensive tutorial. Learn to create fluent DSLs by building a Jenkins pipeline example from scratch, using only plain Groovy without additional libraries or build tools. Explore key concepts such as closure delegation, @DelegatesTo annotation for code completion, Groovy's "with" method, and various DSL classes. Master the implementation of pipeline steps, utilize @NamedParams and @ClosureParams annotations, and run the example with static compilation enabled. Gain practical insights into Groovy DSL development and enhance your programming skills in just 23 minutes.
