Final answer:
To create a Groovy library, you can choose between Groovy 2 and Groovy 3 depending on your specific requirements and compatibility needs.
Step-by-step explanation:
To create a Groovy library, you can use Groovy scripting. There are two main versions of the Groovy scripting language: Groovy 2 and Groovy 3. The choice of which version to use depends on your specific requirements and compatibility needs.
Groovy 2 is the stable version that has been around for a longer time. It has broader library support and is widely used. If you have existing code that relies on Groovy 2, it would be best to stick with it to maintain compatibility.
Groovy 3 is the newer version that brings performance improvements and additional features. It is recommended for new projects or if you need specific features introduced in Groovy 3. However, it might not have the same level of library support as Groovy 2, so it's important to consider your project's dependencies.
