QtCreator will always re-parsing project while saving file

Hi,

I am using Qt Creator 4.9.0, and I open it with my old working project.

And when I saved file in creator, it will always "re-parsing" the whole project

QtCreator will always trigger re-parsing the whole project while saving file.

My previous Qt Creator version is 4.5.0, and it doesn't have this issue.

Thanks,

Jeremy
