Open GROOVY File
GROOVY is a powerful, flexible and lightweight scripting language designed for the Java platform. GROOVY scripts (.groovy files) utilize simple, Java-like syntax that enables developers to write Java applications more efficiently and effectively.
GROOVY Script Files
GROOVY scripts commonly have a .groovy extension. These are plain text files with codes that adhere to the GROOVY scripting language. Normally, the .groovy extension is opened using a text editor like Notepad++, Emacs, or Sublime Text. But for an ideal programming experience, it's best opened with an Integrated Development Environment (IDE) like IntelliJ IDEA or Eclipse. You can download IntelliJ IDEA from here or Eclipse here.
GROOVY with Jenkins
One of the popular uses of the GROOVY language is writing scripts for the Jenkins automation server. Jenkins uses the GROOVY Scripting Language as its primary interface for programmatically configuring jobs. If you have .groovy files specifically for Jenkins, you open and use them in the built-in GROOVY script console with Jenkins. You can learn more about Jenkins from the official documentation here.
GROOVY with Gradle
The gradle build tool uses GROOVY as its default scripting language. A developer defining a project can use .groovy files to create dependencies, plugins, tasks, etc. In this case, you open and use the .groovy files using the Gradle Daemon that comes with the Gradle installation. Visit the Gradle User Manual here for more information.
"GROOVY File Important Information"
The .groovy file extension is primarily associated with the GROOVY programming language. While they're indeed ordinary plain text files that can be opened with any text editor, it's best to use an IDE for better GROOVY syntax highlighting and code completion. Also, take note that .groovy files used for specific platforms like Jenkins and Gradle may often require those specific platforms to be opened and utilized correctly.
