Is there a Maven plugin that allows you to check if there is a newer version of Maven itself?
Say, you are using Maven 3.3.3 and now a new version of Maven 3.3.9 is released. I'd like to know that there is a new version available.
The question Maven check for updated dependencies in repository deals with showing any dependency updates. That is not this question. However, please see the comments for this question of how an answer in Maven check for updated dependencies in repository solves the problem.
