How Do I Integrate Groovy with Java? In many scenarios, Groovy is ideal for the task at hand—such as in rapid prototyping or when building modular applications that can be extended with macros or plug-ins. Such extensions can be built with Groovy and seamlessly embedded in your application without requiring a long and tedious development and deployment cycle. These applications can benefit greatly from Groovy’s expressiveness, brevity, and powerful features. In other situations, however, Groovy might not be the best solution.
