I get the following warning for included files:

12:09:40,657 |-WARN in ch.qos.logback.core.joran.util.ConfigurationWatchListUtil@7c959fa1 - Null ConfigurationWatchList. Cannot add file:/D:/dev/.../logback-lilith.xml

Scanning is off.
I configure logback in the following way:

JoranConfigurator configurator = new JoranConfigurator();
configurator.setContext(loggerContext);
loggerContext.reset();
configurator.doConfigure(new ByteArrayInputStream(config.getBytes("UTF-8")));

The generated main configuration (variable config) contains mainly includes to files within the file system.
