fastlane: Explicit provisioning_profile_path not used?

Original issue by @vittoriom - Imported from fastlane/gym#69

I’m using gym to build an enterprise version of our app. Just for this task it should use an explicitly provided provisioning profile and code signing identity, that override the ones defined in the project.

I’m building with the --verbose flag since after the first try I saw that it was using the wrong (as defined in the Xcode project) provisioning profile instead, but it looks like the generated build command doesn’t include any parameter for passing the specified provisioning profile.

Is there any step I’m missing?

Generated build command:

set -o pipefail && xcodebuild 
-scheme '[REDACTED]' 
-project './[REDACTED].xcodeproj' 
-configuration 'Release' 
-destination 'generic/platform=iOS' 
-xcconfig 'config/Debug.xcconfig' 
-archivePath '/Users/vmonaco/Library/Developer/Xcode/Archives/2015-08-27/[REDACTED] 2015-08-27 12.48.13.xcarchive' 
archive | xcpretty

The command I used is:

gym 
--xcconfig "config/Debug.xcconfig" 
--codesigning_identity "iPhone Distribution: [REDACTED]" 
--provisioning_profile_path: "../CodeSigning/Enterprise.mobileprovision" 
--scheme "[REDACTED]" 
--configuration "Release"
--verbose

After xcodebuild finishes, I got the following command:

/usr/bin/xcrun 
/tmp/PackageApplication4Gym 
-v /Users/vmonaco/Library/Developer/Xcode/Archives/2015-08-27/[REDACTED]\ 2015-08-27\ 12.48.13.xcarchive/Products/Applications/[REDACTED].app 
-o '/Users/vmonaco/Library/Developer/Xcode/Archives/2015-08-27/[REDACTED].ipa' exportFormat ipa --sign 'iPhone Distribution: [REDACTED]'

But nowhere I can see the embedded provisioning being set.
