kandi X-RAY | groovy Summary
Groovy is a powerful multi-faceted programming language for the JVM platform. It supports a spectrum of programming styles incorporating features from dynamic languages such as optional and duck typing, but also static compilation and static type checking at levels similar to or greater than Java through its extensible static type checker. It aims to greatly increase developer productivity with many powerful features but also a concise, familiar and easy to learn syntax. It integrates smoothly with any Java class or library, and immediately delivers to your application powerful capabilities, including scripting support, Domain-Specific Language authoring, runtime and compile-time meta-programming and functional programming.

QUESTION
I'm trying to understand the syntax and methods of the following groovy script used in a jenkins pipeline:
...ANSWER
Answered 2021-Jun-15 at 00:27This is a map that contains maps. [:] is the literal syntax for an empty map. Otherwise the map would be null and you couldn’t add anything to it. The map gets populated with 2 more maps. The argument you pass in decides which of the 2 maps is returned, if the argument doesn’t match either content1 or content2 the function returns null.
If you have groovy installed on your computer you can try your posted code out in groovyConsole and see what it does.

Vulnerabilities
Install groovy
You can use groovy like any standard Java library. Please include the the jar files in your classpath. You can also use any IDE and you can run and debug the groovy component as you would do with any other Java program. Best practice is to use a build tool that supports dependency management such as Maven or Gradle. For Maven installation, please refer maven.apache.org. For Gradle installation, please refer gradle.org .
