quarkus dev
 

starts quarkus in devmode no matter where you are in the directory structure and no matter what build system (gradle,maven,jbang) you are using.

similarly
`quarkus build` will do the "right" thing for building the app no matter the underlying build system.

for more complex scenarioes users will fallback to the native build system - these are here to just make it simple and uniform for users but also makes it possible to unify ci scripts and documentation.
