Groovy Scripting

Groovy Scripting

for Automation and Enterprise Development - 2 days

Practical Groovy Programming for Real-World Automation, Integration and DevOps

Groovy is widely used across enterprise environments for automation, CI/CD pipelines, build management, system administration, API integration, data processing, and JVM-based application development. Its concise syntax and seamless Java interoperability make it an ideal language for rapidly developing scripts and automation solutions without sacrificing access to the extensive Java ecosystem.

This intensive hands-on course focuses on practical Groovy development from the first session onward. Participants will spend the majority of the course writing code, building scripts, processing data, integrating with external systems, and implementing automation solutions.

The instructor brings over 30 years of industry experience and delivers real-world content based on current enterprise requirements rather than academic theory.
