1) Upgrade to latest gradle wrapper which works with Java 11 and drop findbugs plugin
2) Upgrade sass package to the latest version
3) The method getClass().getClassLoader() does not yield a URLClassLoader,
so the cast failed. Revise to call method getResource() to fetch the
MANIFEST.MF file. Must be tested with Java 8 to ensure compatibility. I checked the API docs and it should work.
