quarkus build and dev for uniform access to common build tasks no matter the underlying build system

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.
