Description

In Alloy, the "Resources" directory is essentially recreated on every build via compiler plugin. In order for the generated "Resources" directory to reflect changes made in the Alloy "app/assets" directory (added/removed files), we need to delete then re-create the "Resources" directory each time. Alloy maintains the platform-specific folders in "app/assets", so generally this isn't an issue. The problem arises when a developer would want to import an Alloy project that has no "Resources" folder already in it. From an Alloy developer's perspective, the "Resources" folder is unnecessary baggage since all things that would be contained in it can be found throughout the "app" directory. It would likely be common that Alloy projects in version control won't even keep the "Resources" directory. When a developer imports an Alloy project without a "Resources" directory, or has an existing Alloy project and manually deletes the "Resources" directory, then attempts to run on any platform, they will encounter the following errors:

The reason this seems to occur is that the above validation is happening before the compiler plugin has a chance to repopulate the Resources directory. Is it possible for the compiler plugin to run before this validation? If not, a more complex method of tracking differences between the changes in the "app" directory and the "Resources" directory will need to be maintained by Alloy.

Steps to Reproduce

Create a new Titanium mobile project with the Alloy template

Delete the "Resources" directory

Attempt to run for android or ios

To note, placing an empty "iphone" or "android" folder, depending on the build target of course, will cause the build to execute as normal. There doesn't need to be anything else in the folders, so it seems as though it is unnecessary to have this validation before the compiler plugin processes. Unfortunately I can't do anything on the alloy side until the compiler plugin fires, but it is never reached.

bump, would be nice to get a fix version or something on this one. The Resources directory is hidden in Alloy projects now, but it still needs to exist or the CLI will crash attempting to create the app.
