The Vaadin Gradle plugin has a clear landing page with the documentation: https://github.com/vaadin/vaadin-gradle-plugin/

However, the official Vaadin Maven Plugin has no documentation page at this point:

• https://github.com/vaadin/maven-plugin is a Vaadin 8 plugin, or something deprecated
• The sources are at https://github.com/vaadin/flow/tree/master/flow-maven-plugin but there is no documentation
• Search for "maven" at https://vaadin.com/docs/index.html returns nothing usable
• There is a bit of documentation at https://vaadin.com/docs/v14/flow/production/tutorial-production-mode-basic.html

A succinct page describing all goals and pointing to example project is much needed.
