I\'m trying to build my application using jenkins pipeline using shell command. Below is the command i\'m using to build the app.
sh \'xcodebuild -workspace proj
I have had a similar problem for weeks. Since updating to Xcode 10 every aspect of the build Jenkins did would be successful except I would get that error and the build would fail. Directly building, signing, etc. in Xcode was fine.
The solution in my case was the Xcode 10.1 update. The errors you list still exist in the Jenkins output. However it no longer causes Jenkins to fail the build.
Sadly I don't actually know what caused the failure so I don't have any further insight.
