This is absolutely necessary. We're currently mainly using https://github.com/BestSolution-at/maven-osgi-plugin to run Equinox-based applications like PDE does.
Unfortunately, the following issue bndtools/bnd#4031 was closed.
I think it would be cool to have something like PDE's run configurations directly within bnd/bnd-maven-plugin to launch projects from target/classes instead of packaging everything into jar files first.
