Selenium starts old chromedriver version

In my build.gradle file I have the following dependency:

compile group: 'org.seleniumhq.selenium', name: 'selenium-chrome-driver', version: '3.11.0'

However, whenever I start my tests, selenium seems to be using an old version of ChromeDriver, as it outputs in the console:

Starting ChromeDriver 2.31.488774 

Does anyone know why this is happening?
