Xcode agent JOB fails if generate IPA

[Tech GOFAR]

I have the same problem as described here
https://community.atlassian.com/t5/Bamboo-questions/xcodebuild-fails-with-xcodebuild-error-is-not-a-workspace-file/qaq-p/652566

However, topic is dead over there.

User defaults from command line:
16-May-2018 11:05:02	IDEArchivePathOverride = /Users/me/Desktop/Builds/iOS-2.xcarchive
16-May-2018 11:05:02
16-May-2018 11:05:02	Build settings from command line:
16-May-2018 11:05:02	SDKROOT = iphoneos11.3
16-May-2018 11:05:02
16-May-2018 11:05:02	xcodebuild: error: '' is not a workspace file.

Failing task since return code of [/usr/bin/xcrun -sdk iphoneos11.3 xcodebuild -workspace  -scheme Staging -sdk iphoneos -configuration Staging archive -archivePath /Users/me/Desktop/Builds/iOS-2.xcarchive]


As you can see the line from logs does include -workspace key word. However, I do not use workspace ;/ I do use xcodeproj file.
That's what I have specify in my JOB.

It does work if I won't generate an IPA file. If I do select to generate IPA file it fails on this line
