DEPRECATED! build Fuchsia and push to device
usage: fx build-push [ninja option,...] [target,...] Deprecated: This command is deprecated as it is misleading. Packages in Fuchsia are only cached, not installed, and the cache is updated on-demand when a component is launched from a fuchsia package URL. An attempt to "push" a package as implemented here only performs one of these resolutions, and may or may not influence what happens "next" if a user "runs" a component url. As such this command influences a poor mental model of the system and should be avoided. Build ALL targets. After building all the targets, push the ones that were supplied to this command. If no targets were specified push all of them. The packages are pushed to the device specified. If no device is supplied explicitly this will push to the single connected device. If multiple devices are connected and no device is specified, pushing will fail.
