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.

            This 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

            Apache Groovy provides extension methods to aid with creating temporary directories. Prior to this fix, Groovy's implementation of those extension methods was using a now superseded Java JDK method call that is potentially not secure on some operating systems in some contexts. Users not using the extension methods mentioned in the advisory are not affected, but may wish to read the advisory for further details. Versions Affected: 2.0 to 2.4.20, 2.5.0 to 2.5.13, 3.0.0 to 3.0.6, and 4.0.0-alpha-1. Fixed in versions 2.4.21, 2.5.14, 3.0.7, 4.0.0-alpha-2.
            A sandbox bypass vulnerability exists in Jenkins Groovy Plugin 2.1 and earlier in pom.xml, src/main/java/hudson/plugins/groovy/StringScriptSource.java that allows attackers with Overall/Read permission to execute arbitrary code on the Jenkins master JVM.

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 .
