Groovy Interactive Console
You can open an interactive Groovy console in any project including a Java one and use the console as a temporary file to write and evaluate your code.
If dependencies in your project contain a Groovy library then the specified Groovy library is used to launch the Groovy console. If the dependencies do not contain a Groovy library then the bundled Groovy library will be used.
From the main menu, select.
If you have more than one module in your project, click the project's name on the console toolbar and select a module from the list to change a classpath for the console.
The Groovy console starts in a separate tab in the editor.
Perform different actions inside the Groovy console
You can enter code, the coding assistance is available as you type, or paste code from a different file. Press Ctrl+Enter or click to execute code and view the results in the Run tool window.
You can refer to a class from the Groovy console. Type the name of the class you need, select it and press Ctrl+B to jump to its declaration.
If you have an import statement in your code, you can run a partial selection of code omitting the import statement. The Groovy console will include the omitted part during the execution.
