fastlane: Scan hangs when getting build settings

New Issue Checklist

Updated fastlane to the latest version
I have read the Contribution Guidelines

Issue Description

Scan hangs when getting the build settings:

xcrun xcodebuild -showBuildSettings -workspace './App.xcworkspace' -scheme 'AppTests'

A couple things to note:

I thought that it was related to https://github.com/fastlane/fastlane/issues/1844 since it was the last command showing up in the logs, but after looking at the stacktrace when I force quite fastlane, it seems that it’s actually hanging on showBuildSettings.
I can reproduce the freeze by running the -showBuildSettings command manually, though it only happens one time out of five, something like that.
It happens consistently when running in a CI environment (circleci 7.3)
It started happening after I removed all files in the App target from the AppTests target. Instead, I now have @testable import App everywhere. This change required to modify my Podfile to have different pods for the AppTests target (see below)
DerivedData is relative to my project directory.

Complete output when running fastlane, including the stack trace and command used

Please note that I modified fastlane_core’s sources to show the build settings command, which is why it shows up in the logs. If I hadn’t, only the -list command would appear.

Note that the command above doesn’t exit (1 time out of 5), I have to force kill it.

Thanks @fcy! I’m going to bump that pull request internally so we can hopefully merge soon 👍

@TKBurner I can see this issue on several App and Library projects. That leads to a hanging build server. PR #5188 solves the issue. What’s the reason not to accept it? I don’t want to remove fastlane from our projects, but that workaround is currently under discussion in my team.

We hit this again in a different project, again running on Jenkins. Trying all these things fixed it;

Unticking show on all of the schemes that aren’t actively used (for example, all the pods)
Unticking Shared on all the shared schemes
Reticking Shared on all the shared schemes
Changing some of the Scheme settings (like the targets that should be built)

It seems that sometimes the project / scheme files just needs something to change to fix this, these steps above seem to somehow kick it into action.

Hi all, gym 1.9.0 💪 and scan 0.12.0 🔍 have been released to pick up these fastlane_core improvements.

To get updated and try them out, please run [sudo] gem update gym scan 🚀

mfurtak on Sep 8, 2016

Thanks for merging! It works 😃

hotbott on Sep 8, 2016

Hi all, we’ve shipped a workaround (#5626) and timeout/retry solution (#5188) as part of fastlane_core 0.51.0 🚀

Thanks very much for your help! Please let us know how it looks 👍

mfurtak on Sep 7, 2016

@ilsinszkibal thanks for sharing your workaround, unfortunately it does not work with my projects 😢

Xcode 8 beta 4 still has the same problem #5163
PR #5188 seems to fix the issue

hotbott on Aug 3, 2016

@ilsinszkibal Was it just the last message in your log or you performed some debugging? I found out that the real command in my case was xcrun xcodebuild -showBuildSettings ... despite that last message was xcodebuild -list -workspace .... (lack of logging). For me it’s still an annoying issue with frequent CI build failures but I’ve added a check call to xcodebuild with small timeout to get those errors faster.

FWIW we don’t use rvm/rbenv, we use the system Ruby. And we keep OS X up to date.

fcy on Jul 26, 2016

Any updates on this? I am also seeing this happen once we upgraded to Xcode 7.3.1

arunks on Jul 26, 2016

Any news or plans to create a new PR?

hotbott on Jul 21, 2016

@bencollier Thanks for documenting your fix!
