how to capture wget command output inside groovy

Question

I am execution a wget command inside my groovy code, the command is like this:

cmd /c C:/wget.exe -q -O - <my-URL>

When i actually run this command from cmd or windows run util, it works fine. But when i try to run this from within my groovy code, I don't see the output. How can i capture the output of this within groovy.

Thanks!

groovy has a specific way of grabbing that content that is the more general java version — dstarh, Oct 06 '11 at 20:09

Instead of using wget why not just use groovy to get you the content:

def data = new URL(myUrl).getText()

"cmd /c C:/wget.exe -q -O - <my-URL>".execute().text

But new URL("<my-URL").text might be a better way to load an url without relying on wget.
