Fix broken build on Windows OS if the schema contains references to other schema files

Fix broken build on Windows OS if the schema contains references to other schema files. The same project configuration works under Linux without issues.
This is because the ${project.basedir} maven variable contains \ in the string representation and this causes the resolve of referenced schema files.

@wing328 Thanks, I removed the tabs.

[wing328]

did you test this fix locally to confirm it's working for your use cases on Windows?

[akuhtz]

Yes, I built it locally and tested it with my project before I created the PR.

[wing328]

ok. let's give it a try
