Can support the source directory can be configured？

[lanmolsz]

Maven project only supports one source directory, sometimes may need more than one source directory, such as maven-compiler-plugin generatedSourcesDirectory, can support it? Configure them by adding a parameter?

The current version only supports configuring additional packages via the dependencyPackagesList parameter, hoping to add this configuration in the next release.

I've never tried this myself but I see that context class loader is used and I expect it to work with multiple source directories.
Anyway, RAML generation is not top priority atm so please consider a PR.
