How to catch GroovyShell output?

Question

I create a groovy engine with the GroovyShell class. Then I run a bunch of statements with the "evaluate" method.
Is there a way to catch the output of the engine so I can get "println" calls output?
Currently it goes to stdout although it is a swing application.

You can just assign your custom Writer (eg. StringWriter) to out property in the binding and pass it to the GroovyShell.

def binding = new Binding();
binding.setProperty("out", new YourWriter())
new GroovyShell(binding);
