I got an issue with Xcode's Bot. It always returns the "User canceled the operation. Command /usr/bin/codesign failed with exit code 1" error string after running the command below:
/usr/bin/codesign --force --sign <MY_PRIVATE_KEY> --entitlements /Library/Developer/XcodeServer/Integrations/Caches/2cdd321641e8c114e4eba9819b017479/DerivedData/Build/Intermediates/MyApp.build/Debug-iphoneos/MyApp.build/MyApp.app.xcent /Library/Developer/XcodeServer/Integrations/Caches/2cdd321641e8c114e4eba9819b017479/DerivedData/Build/Products/Debug-iphoneos/MyApp.app
I can run this command in Terminal with sudo. I'm using Xcode 6.3.1 and OS X Server 4.1.53 in my Mac 10.10.4.
Thank for your help.
