I have a run script build phase that is trying to do custom code signing of a helper tool after it has been copied into the app package, so I have set both input and output files to the same thing, ${CONFIGURATION_BUILD_DIR}/$CONTENTS_FOLDER_PATH/Helpers/V40SSApp. But when I try to build, I get an error
invalid task ('PhaseScriptExecution Run\ Script /mypath/Debug/installer.build/Script-BED5B762297F4C4C00C96242.sh') with mutable output but no other virtual output node
I would guess that the "mutable" bit has something to do with the input and output being the same, but I don't get what it's complaining about.
