Jenkins, Carthage and EearlGrey issue

Hi folks,

Im really struggling with this issue. Running Carthage with EarlGrey with Carthage under Jenkins, I get the following error
```
*** Building scheme "EarlGrey" in EarlGrey.xcodeproj
Build Failed
Task failed with exit code 65:
/usr/bin/xcrun xcodebuild -project /Users/doronkatz/.jenkins/workspace/Integration\ Test/Carthage/Checkouts/EarlGrey/EarlGrey.xcodeproj -scheme EarlGrey -configuration Release -derivedDataPath /Users/doronkatz/Library/Caches/org.carthage.CarthageKit/DerivedData/9.0.1_9A1004/EarlGrey/1.2.0 -sdk iphoneos ONLY_ACTIVE_ARCH=NO CODE_SIGNING_REQUIRED=NO CODE_SIGN_IDENTITY= CARTHAGE=YES archive -archivePath ./ SKIP_INSTALL=YES GCC_INSTRUMENT_PROGRAM_FLOW_ARCS=NO CLANG_ENABLE_CODE_COVERAGE=NO (launched in /Users/doronkatz/.jenkins/workspace/Integration Test/Carthage/Checkouts/EarlGrey)

This usually indicates that project itself failed to compile. Please check the xcodebuild log for more details: /var/folders/68/946ywfgx3jq3bwhy02std9tc0000gn/T/carthage-xcodebuild.pdeB5o.log
Build step 'Execute shell' marked build as failure
Finished: FAILURE
```

In my Cartfile, i have:
`github "google/EarlGrey" "master"`

If anyone has ant thoughts would be greatly appreciated!
