During the current NetCAT game, I pointed out that division of projects into categories is not logical. While Ant based Java project resides under Java > Java Application (category > concrete project type), the Maven based one can be found under Maven > Java Application (Maven > concrete project type). I suggested to join both wizards and let user choose the build system in a new wizard step.

Jiří Kovalský (NetBeans quality manager) requested me to file an issue. I just did it. Issue #224999 [1]

If you want to second this, please feel free to vote for it.
