Using SW4STM32 version 2.0, I get the same error.
It happens after a “clean” command of the project too. It seems that this is still not fixed (or maybe in the IDE?).
I use CubeF4 version 1.16.0, the latest.
This happens to this project:
STM32Cube_FW_F4_V1.16.0\Projects\STM32F429I-Discovery\Applications\FatFs

I also have to compile about 3 times until it works.
The first time I get the same error:
Project->Build Project
Errors occured during build.
Errors running builder ‘CDT Builder’ on project .
Resource ‘/Debug/sources.mk’ does not exist.

The second time I get this error:
Project->Build Project
Errors running builder ‘CDT Builder’ on project
Resource ‘/Debug/Application/SW4STM32’ does not exist.

And after that, it finally builds properly.

It seems that on other projects (like building the official full demos of the boards) it works fine.
Hence I suspect that the fixes were made only for the demo projects and not for all projects. I would recommend doing it for all other projects too.
