binary-only dependencies don't have a version file for --cache-builds

[mdiep]

• carthage version: 0.21

Cartfile

binary "https://some/my-project.json"

Carthage Output

*** No cache found for my-project, building with all downstream dependencies

Evidently this wasn't covered by #1850. 😞

@mdiep hmm—quite strange! I tested that version files are being outputted. See below:

$ mkdir TestBinary
$ cd TestBinary

$ carthage version
0.21.0

$ echo 'binary "https://www.mapbox.com/ios-sdk/Mapbox-iOS-SDK.json"' > Cartfile

$ carthage bootstrap
*** No Cartfile.resolved found, updating dependencies
*** Downloading binary-only framework Mapbox-iOS-SDK at "https://www.mapbox.com/ios-sdk/Mapbox-iOS-SDK.json"
*** xcodebuild output can be found in /var/folders/9s/rl0z7g591cs9frc53y6cbpzm0000gq/T/carthage-xcodebuild.gSiAcr.log

$ carthage build --cache-builds
*** xcodebuild output can be found in /var/folders/9s/rl0z7g591cs9frc53y6cbpzm0000gq/T/carthage-xcodebuild.NiXbi0.log

$ ls -al Carthage/Build

  ],

  "watchOS" : [

  "tvOS" : [

}

Is there something I'm missing—perhaps another example binary project to try that doesn't perform like this?

Hmm… It looks like the issue is that I just ran carthage build and not carthage bootstrap.

So I guess we can chalk this up to state from a pre-0.21 checkout.
