In Maven, you can use “mvn site” to generate a documentation site for your project information.
mvn site
The generated site is under your project “target/site” folder.

mvn site example

See a list of files generated via “mvn site” command.

Note
Personally, i do not like this feature much, because it didn’t bring much benefits, who want to know the project information?
