It seems it is possible on mvnrepository.com to associate an icon and some tags to a project. Here, for instance, the page about JUnit, where the two elements are highlighted.
Do you know how to add this info to the project published in the repo ? Maybe something to the project pom.xml file should be added ?
Thanks in advance.
The icon question was meantime answered elsewhere on StackOverflow:

So the icon comes from SCM (github). Although, looking at the example project posted by Aurasphere in the above linked answer, the icon might have come from project website as well.
If icon comes from SCM site, perhaps tags do too. Chances are mvnrepository is crunching the available data in some way to reduce noise, so it might not be a 1:1 relationship.
