extends file location not correctly resolved on linux

[codemonstur]

When using this code:

public static void main(final String... args) throws IOException {
    final Path path = Paths.get("src/main/resources/page.pug");
    System.out.println(path.toAbsolutePath().toString());
    final String html = Pug4J.render(path.toAbsolutePath().toString(), new HashMap<String, Object>());
    System.out.println(html);
}

And referring to this path using extends: ../include/skeleton.pug. I get this error on debian (running in windows):

$ java -jar target/pug-1.jar
/mnt/c/Projects/test/pug/src/main/resources/page.pug
Exception in thread "main" class de.neuland.pug4j.exceptions.PugParserException: The template [../include/skeleton.pug] could not be opened. Maybe it is located outside the base path?

I setup some more testcases for the static PUG4J API and resolved some issues with file path handling. Please try 2.0.0-alpha4

Yes it now loads the extends file. I did notice however that when I call Pug4J.render(fullPath, new HashMap<>()); with a path that doesn't exist I get an NPE:

Please check alpha-5. There should be a FileNotFoundException now.

Yes it throws a FileNotFoundException now. Great!
