Regular expression for the file name without extension in Groovy

Are you willing to get rid on the file extension in groovy, but don't know how to do that ? This post is for you. If you are a programmer, you will not certainly want to read many useless lines before getting what you.
This line is for you:

file.name.replaceFirst(~/\.[^\.]+$/, '')
