Gradle Project Build Failure: Internal Error, Could not normalize path

I am trying to build a gradle project in Windows 8 using IntelliJ. The build fails “because of an internal error”. It lists the following exception:

org.gradle.api.UncheckedIOException: Could not normalize path for file ‘C:\cygwin\home\philb_000\IdeaProjects\dsp-ui-jsf\src\main\webapp***.xhtml’.

This is then followed by about 100 or so issues.

My technical knowledge of this sort of thing is incredibly limited. Until now I have been running this project in a Linux virtual machine in order for it to work, but am having issues with that as well. I have just tried the same approach with cygwin as you can see.

Any insight is appreciated, thanks!
