Trouble building a dependent repository that requires Carthage

Our project requires a private repo that requires Carthage to be bootstrapped. The main repo has a workspace that includes the main project file and the dependent project file. This is essentially what we’re trying to achieve:

  1. Clone the private repo with a github user key, checking out the same branch name as the main repo.
  2. Bootstrap Carthage for the dependent repo.
  3. Build the main repo.

Bootstrapping Carthage in the dependent repo can take upwards of 30 minutes, so ideally this needs to be cached (we’re using the technique described here: https://robots.thoughtbot.com/caching-carthage-con-circleci).

This is what our circle.yml file looks like:

machine:
  environment:
    LC_CTYPE: en_US.UTF-8
    XCODE_WORKSPACE: MyApp.xcworkspace
  xcode:
    version: "8.3.2"

checkout:
  post:
    - git clone -b $CIRCLE_BRANCH git@github.com:Foo/dependent-repo.git
    - mv dependent-repo ../dependent-repo

dependencies:
  override:
    - cd ../dependent-repo/Swift && bin/bootstrap-if-needed
  cache_directories:
    - "../dependent-repo/Swift/Carthage"

test:
  override:
    - set -o pipefail &&
      xcodebuild
        CODE_SIGNING_REQUIRED=NO
        CODE_SIGN_IDENTITY=
        PROVISIONING_PROFILE=
        -destination 'platform=iOS Simulator,OS=latest,name=iPhone 7'
        -workspace 'MyApp.xcworkspace'
        -scheme "MyApp Stage"
        clean build test |
      tee $CIRCLE_ARTIFACTS/xcode_raw.log |
      xcpretty --color --report junit --output $CIRCLE_TEST_REPORTS/xcode/results.xml

The build always fails during the cd ../dependent-repo/Swift && bin/bootstrap-if-needed step. It appears like ../dependent-repo/Swift exists, but is always empty.

I’ve even tried something like this, just to debug:
git clone -b $CIRCLE_BRANCH git@github.com:Foo/dependent-repo.git && mv dependent-repo ../dependent-repo && ls -l ../dependent-repo/Swift

It’s still empty, even though the repo was clearly just cloned. What’s going on? How do I fix this? And if we’re going about this the wrong way, what is the solution?

Hey,

Have you tried SSH-ing into your build and checking everything out yourself?
