Groovy way to remove file extension? [duplicate]

Question

I'm wondering if there is a "Groovy" way to remove the file extension from a filename.

The current solution relies on the apache commons io package:

import org.apache.commons.io.FilenameUtils

String filename = '/tmp/hello-world.txt'
def fileWithoutExt = FilenameUtils.removeExtension(filename)

You can do something like this:

filename[0..<filename.lastIndexOf('.')]

To remove everything after the last . in the String.

Or the slightly prettier:

filename.take(filename.lastIndexOf('.'))

NB: if a file haven't an extension it will be not matched
