xcodebuild doesn't see my new 'source trees' setting

Question

I have a change in my xcode preferences "Source Trees", but the command-line build tool 'xcodebuild' does not pick it up. It pick up the previous value. (The project inside xcode itself does build with the new value).

I think I need to delete an xcode preference file somewhere..... Does someone know where the preferences are stored? But perhaps something else is needed.... Who can help me out?

Answer 1

It seems that deleting the file ~/Library/Preferences/com.apple.dt.Xcode.plist did the trick.
