I'd rather not to pass `this` reference to this method, especially if the
only thing we need is a couple of properties from 'locations' object
(`this.locations.platformWww` and `this.locations.www` at L120). Maybe just
pass these properties as an arguments, or revert to previous signature?
> Preparing platforms should skip copying files which haven't changed

> Key: CB-11117
> URL: https://issues.apache.org/jira/browse/CB-11117
> Project: Apache Cordova
> Issue Type: Improvement
> Components: Android, iOS, Windows
> Reporter: Jason Ginchereau
> Assignee: Jason Ginchereau
>
> Many cordova CLI commands include a "prepare" operation, including 'cordova
> build', 'cordova run', 'cordova plugin add', and more. Every time each of
> those commands runs, the target platform is "prepared", which involves
> copying all files from the [<project>/www,
> <project>/platforms/<platform>/platform_www, <project>/merges/<platform>] to
> the platform's target www folder, as well as copying a bunch of icons and
> splash screens to platform-specific locations.
> For the very first prepare of a platform, all that file copying is necessary.
> But most of the time after that most of the files being copied have not
> changed and therefore don't really need to be copied again. So the typical
> developer inner loop (edit a few source files, build and run the app, repeat)
> is a lot slower than it could be for a Cordova project, especially one that
> includes a significant number of source files or resources.
> Instead, Cordova should be smart enough to skip copying of files that haven't
> changed, based on their last-modified timestamp. (But also there should still
> be a way to force a clean/full/non-incremental build if desired.)
