What's the matter with IntelliJ's Groovy console?

Question

When I try to use the groovy console it just doesn't seem to recognize and understand the previous stements entered. And code completion does not work either. Below is a VERY simple example that fails. Creating a list and trying to add an integer to that list. The created list isn't found!

> def list = []
[]
> list.add(10)
groovy.lang.MissingPropertyException: No such property: list for class: ideaGroovyConsole
Possible solutions: class

Answer 1

Don't def and you should be good.

> list = []
[]
> list.add(10)

The behaviour is more like groovyShell than groovyConsole.

Perhaps this link explains why: http://groovy-lang.org/groovysh.html#GroovyShell-Variables
