Hi, all
I always get a exception when Eclipse auto-build after cleaning all projects.
But if I touch the file and save it, the triggered auto-build is always  successful.

It really bothers me.

I'd need to recreate this to dig into it - is it by any a public project? Can you trim down your project to a smaller one that exhibits the same problem?  I can stick in a guard but it will likely have unexpected consequences.  Compilation results shouldn't forget the source file they came from.
