Sharing can cause major issues if, for example, deployed files / folders are moved / renamed in one of the branch projects. Hence resolution to this problem was to provide an error message, which is what you're currently seeing. The workaround would be to assign deployment area to your main project / stream, or to some 'shared' stream, and then merge updates from branches into that stream and then deploy them.
This tool uses the concept of the ancestor file against which all other files (derivatives) are compared based on the output from 'GNU diff'. The resultant file of the merge operation is the target file which contains all text consistent across the files together with all the changes which been made in the derivative files with the exception of conflicts which have to be resolved by the user.
