Gr8Conf US 2018: Add some Groovy magic to your Java project – why, where and how to leverage Groovy in a Java codebase

Given the fact that Groovy is such a powerful and flexible technology, with a very flat learning curve for Java developers, it is surprising how little it's used in Java projects and how many Java devs there are that have never coded a line of Groovy code. As a result, they are missing out on a very strong device in their programming toolbox. This talk is dedicated to all the Java developers interested in making their life easier by adding some Groovy goodness to their projects. I will present practical and easy ways of incorporating Groovy into any Java project, including such areas as tests, generating demo data, scripting, building your project and, finally, enhancing your Continuous Delivery infrastructure.
