This PR creates a new source set called
systemFileSystem
thatjvm
andnative
depend on, and makesFileSystem.SYSTEM
available there.We can't remove the existing
SYSTEM
declarations in the companion objects ofFileSystem
, and we can't introduce a companion object in the shared source set as it could not be further refined in more specific source sets.Therefore, this new declaration is added as an
expect
extension on the companion. This lets code targeting JVM and native platforms resolve to the extension in common code, while they will actually use the properties of the companions directly when compiled.To make this change easier to test, we add additional platforms to the
samples
project, and a sample function that exercises the new property.
