path_not_posix

The path '{0}' isn't a POSIX-style path.

The analyzer produces this diagnostic when a dependency has a path key whose value is a string, but isn't a POSIX-style path.

The following code produces this diagnostic because the path following the path key is a Windows path:

name: example
dependencies:
  local_package:
    path: E:\local_package

Convert the path to a POSIX path.
