This course by kodestree is built for those who already work with Java or JVM systems but need Groovy to stop being a mystery.
Across live instructor-led sessions, in this program, you will write closures, build custom DSLs, automate CI/CD pipelines,
and test with Spock – the same tasks hiring managers look for in Groovy developer roles. By the end of the
course, you’ll complete a portfolio-ready project, not just theory-based exercises.
Prerequisites
There is no specific prerequisites required to enroll in this course, but it is designed for learners who already have
some programming experience. You will benefit most if you have:
- Basic familiarity with Java syntax or any object-oriented programming language.
- A working understanding of build tools such as Maven, Gradle, or Ant.
- Comfort using the command line and Git for version control.
- No prior Groovy experience is required – the course starts with the fundamentals.
Course Objectives
- Understand where Groovy fits within the JVM ecosystem and why organizations use it alongside Java.
- Write idiomatic Groovy using closures, GStrings, the safe navigation operator, and the Elvis operator.
- Build and extend Domain-Specific Languages (DSLs) for automation and configuration.
- Automate builds with Gradle and create Jenkins pipelines using Groovy DSL and shared libraries.
- Test Groovy and Java applications using Spock with mocking, stubbing, and data-driven testing.
- Apply metaprogramming techniques including Categories, ExpandoMetaClass, and AST transformations.
- Package a complete Groovy or Grails application and prepare for certification assessments.
What You Will Learn
- Groovy fundamentals including variables, collections, ranges, and dynamic versus static typing.
- Closures and higher-order functions for writing concise, functional-style code.
- Working with GPath, GString, regular expressions, and operator overloading.
- Dependency management using Grape, including the Maven-backed engine in Groovy 6.
- Object-oriented programming and the Groovy Meta-Object Protocol (MOP).
- Builders such as MarkupBuilder and SwingBuilder for generating XML, HTML, and UI components.
- Gradle build scripts, custom tasks, and multi-module project configuration.
- Jenkins scripted and declarative pipelines along with reusable shared libraries.
- Grails fundamentals including domain classes, GORM, controllers, and the MVC architecture.
- Unit and integration testing using Spock with data tables and interaction-based testing.
- Debugging, performance optimization, and static type checking using
@CompileStaticand@TypeChecked.
